About This Document
This document describes preparation, operation and maintenance of the XYR 6000 Wireless Corrosion
Transmitters. Mounting, installation and wiring are covered in other documents.
Honeywell does not recommend using devices for critical control where there is a single point of failure or where
single points of failure result in unsafe conditions. OneWireless is targeted at open loop control, supervisory
control, and controls that do not have environmental or safety consequences. As with any process control solution,
the end-user must weigh the risks and benefits to determine if the products used are the right match for the
application based on security, safety, and performance. Additionally, it is up to the end-user to ensure that the
control strategy sheds to a safe operating condition if any crucial segment of the control solution fails.

operation and maintenance.

•
Details of topics that relate uniquely to the Honeywell XYR 6000 Corrosion Transmitter,
•
This manual does not cover installation, mounting, or wiring. See XYR 6000 Transmitter Quick Start
Guide (document 34-XY-25-21).
OneWireless network overview
OneWireless is an all digital, serial, two-way communication mesh network that interconnects industrial
field sensors to a central system.
OneWireless has defined standards to which field devices and operator stations communicate with one
another. The communications protocol is built as an "open system" to allow all field devices and
equipment that are built to OneWireless standard to be integrated into a system, regardless of the device
manufacturer. This interoperability of devices using OneWireless technology is to become an industry
standard for automation systems.
1.4
About the transmitter
The XYR 6000 SmartCET Corrosion Transmitter is furnished with OneWireless interface to operate in a
compatible distributed OneWireless system. The transmitter will interoperate with any OneWirelessregistered device.
The transmitter includes OneWireless electronics for operating in a 2.4GHz network. It features function
block architecture.
The transmitter measures the process corrosion and transmits a digital output signal proportional to the
measured variable. Its major components are an electronics housing as shown in Figure 1.
The XYR 6000 transmits its output in a digital OneWireless protocol format for direct digital
communications with systems.
The Process Variable (PV) is available for monitoring and alarm purposes.
The sample time can be configured to calculate the corrosion variables every 30 seconds, or every 1, 2, 3,
4, 5 minutes. This parameter is independent of the publish rate, which has a configuration time of 30
seconds. If the sample time and publish rate are both set to 30 seconds, the corrosion transmitter will
continuously calculate corrosion measurements and publish a new measurement (all four variables) at each
publish rate interval (every 30 seconds). This configuration will result in minimal battery life but provides
almost real time corrosion information. If the sample time is set for five minutes, all four corrosion
variables will be calculated and published within the next 30 second publish rate interval, however the
transmitter corrosion measurement will then go to sleep for 4.5 minutes, until it is time to start the next
sample. This configuration will result in maximum battery life and is the default configuration.
Figure 1 shows a block diagram of the XYR 6000 SmartCET Corrosion transmitter’s operating functions.

Installation
Refer to the XYR 6000 Transmitter Quick Start Guide (document 34-XY-25-21) for installation, mounting
and wiring of your XYR 6000 SmartCET transmitter.
3.2
Configuration
The XYR 6000 SmartCET Transmitter contains the electronics interface compatible for connecting to the
OneWireless network. An operator uses the Wireless Builder application to configure blocks, to change
operating parameters, and to create linkages between blocks that make up the transmitter’s configuration.
These changes are written to the transmitter when it is authenticated by a security key.
3.3
Connecting to network
Use Authentication Device to connect your transmitter to the OneWireless network. See page 28.
3.4
Calibrating the transmitter
Overview
The transmitter is calibrated at the factory. User calibration is unlikely to improve calibration and is not
recommended.
However, calibration is available if desired. For all calibration methods, Wireless Builder must first be
used to prepare the channel for calibration. For access to all calibration methods, refer to Wireless Builder.

Block description
Block types
Blocks are the key elements that make up the transmitter’s configuration. The blocks contain data (block
objects and parameters) which define the application, such as the inputs and outputs, signal processing and
connections to other applications. The XYR 6000 SmartCET Transmitter contains the following block
types.
Block Type
Function
Device
Contains parameters related to the overall field device rather than a
specific input or output channel within it. A field device has exactly one
device block.
AITB
Contains parameters related to a specific process input or output
channel in a measurement or actuation device. An AITB defines a
measurement sensor channel for an analog process variable
represented by a floating-point value. There is one AITB per sensor.
Radio
Contains parameters related to radio communication between the
transmitter and the multimode(s).

Transmit a key to the transmitter. See page
28.
NOT CONN
Transmitter is in between discovery attempts.
If Transmitter does not make a connection
within five minutes, do the following:
• Check that Key is correct for the network
you are trying to join.
• Check that Multinode(s) in the local area
are turned on and are already a secure
part of the network.
• Check if KeyServer is active.
• Check the KeyServer Event Log to see if
the Transmitter is actively trying to join.
Errors in the Event Log show that the
Transmitter is trying to join but that there
are problems. Consult the OneWireless
Wireless Builder documentation for
troubleshooting errors.
DISCOVER
Transmitter has not made a connection to a
Multinode and is in discovery (searching for a
connection to a Multinode). Transmitter will
automatically enter a power saving mode if it
cannot make a connection and will retry later.
Wait for connection. If Transmitter does not
make a connection within five minutes, see
NOT CONN in this table.
SECURING
Transmitter has connected with the network
and is validating its key.
Wait for connection. If Transmitter does not
make a connection within five minutes, see

Step
Action
If the PDA contains no keys, obtain new security keys from the PC
application Key Server Manager.
To do this, select Receive Security Keys. Keys can be received either
through Infrared (by aiming PDA at the infrared dongle) or through an
ActiveSync/USB connection. See Key Server Communication Method
under Advanced options on page 33 for details.
Important: The Comm Method settings must match in the PC’s Key Server
Manager and in the Authentication Device (both must be set to Infrared or
both to ActiveSync) in order for your PDA to receive security keys. See Key
Server Communication Method under Advanced options on page 33 for
details.
When the Authentication Device has valid unexpired keys, aim it at the
transmitter and transmit a key to the transmitter. The transmitter will validate
the key and then use it to make a connection to the OneWireless Network.
The Transmitter may continue to show the diagnostic message “NO KEY” for
a brief time while it validates the key before showing the “DISCOVER”
message.
To verify your transmitter has been authenticated, see the Connection prompt
on the Read Node Info screen (page 31).
To decommission your transmitter from the OneWireless network, select Clear Key and Restart Node.
This clears the transmitter’s key, network and security configurations, and resets the transmitter to its
factory default settings. perform the following steps.
Select Clear Keys from Handheld (under Advanced Options) when:

Note 2.
Note 1: Corrosion rate maximum will depend on the material constants and surface area entered. From a
measurement perspective, it relates to the absolute value of the polarization resistance of the working
electrode. If the polarization resistance is very low (<10 ohms), the instrument will be close to current
saturation. For optimal operation it is preferable to maintain the polarization resistance of the working
electrode at values of >100 ohms. This may be achieved to some extent by changes to the surface area
of the working electrode, thereby optimizing the span of the corrosion measurement.
Note 2: Items shown in brackets are general statements. No specific value can be provided.
Note 3: An exact zero value will not be achieved. It will be almost zero or very small, for example, 0.001
mpy.
Under conditions when general corrosion is prevalent on the material being monitored, the measured
corrosion rate observed as the primary variable (PV) may be expected to show evidence of being stationary
for a short term. In these cases the corrosion rate will tend to exhibit only slight variation in the short term,
perhaps over periods of hours or longer. Any slight process change, such as temperature variability is
often reflected in the corrosion rate behavior. Larger excursions in the corrosion rate may be experienced
if there are more pronounced changes to the environment, for example due to flow rates or changes in
composition.
The secondary variable, Pitting Factor, will typically exhibit a low value under these conditions (for
example, <0.01), although it may exhibit some short term response to abrupt changes in the environment,
for example sudden changes in temperature, flow rate or fluid composition.
The tertiary variable (the B value) will usually fall in a range of 0.010 to 0.030 volts, and will be stable.
The quaternary variable (Corrosion Mechanism Indicator) is largely dependant on the type of material
being studied, but generally, if active corrosion is being observed (>5mpy), it will tend to be significantly
larger than the case for very low corrosion rates.

6. Troubleshooting
6.2. General troubleshooting procedures
If low general corrosion rates are being observed, which are close to instrument baseline (< 0.05 mpy), the
Pitting Factor may appear artificially high (for example, > 0.01).
When localized corrosion is occurring, the observed general corrosion rate values may be in the range 0.1
to 10 mpy or higher, depending on the material and the environment. The Pitting Factor will tend to
exhibit higher magnitude peaks of activity during pit initiation events, whereas propagating pits may be
associated with a general increase in the observed corrosion rate and lower levels of Pitting Factor (<0.1).
The general corrosion rate in the case of propagating pits often exhibits short term variation and is
noticeably less stable than the case for general corrosion. Pitting is often accompanied by increased
variability in the B value. With increasing degrees of pit propagation, the CMI values will also tend to
increase.
6.2
General troubleshooting procedures
The XYR 6000 SmartCET transmitter is designed to operate over a broad range of corrosion rates.
However, most problems associated with the corrosion rate calculation arise when the actual corrosion rate
is extremely high, and there is likelihood that the instrument is approaching or exceeding its stated
operating limits. In some circumstances, this can be remedied by using sensors with a smaller surface
area.
Another factor to be considered is severe diffusion limiting or mass transport control of the corrosion
processes. In this case the B value determination may become difficult, and erratic behavior with very
high values may be observed. Troubleshooting procedures that deal with this condition and general
situations are shown in Table 13.

Symptom
Corrosion rates are very high,
Pitting Factor very low, and B
values are very low.
Possible cause
This problem could be due to a
shorting condition between
probe sensing elements
Action
1a. Disconnect probe and the
corrosion rate should fall.
1b. Remove probe and
physically check for electrode to
electrode contact.
1c. May be caused by the
presence of conductive
corrosion deposits for example,
iron sulfide (B value very low).
2. Use probe with smaller
surface area.
Corrosion rate switches
abruptly from high to very low
levels, Pitting Factor is very
high, and the B value goes to
the current default value.
All corrosion variables are very
unstable exhibiting one or more
of the following:
Corrosion rate unstable, may
drop to very low values
Pitting Factor low when
corrosion rate high and vice
versa.
B values unstable switching
between -20 and 100.
CMI unstable switching from
very low value 0, to large value
for example, > 5000.
36
This situation is symptomatic of
when the (internal) polarization
resistance calculation has
apparently gone to a negative
value, with the result that the
corrosion rate is indeterminate
and a default low value is
returned. Apparent negative
polarization resistances may
occur in situations where the
corrosion rates are very high
and the electrode area is
incorrect for the process
situation.
The electrodes could be too
large. Investigate using
electrodes with a smaller area.
These symptoms are typically
caused by high and variable
corrosion rates in the process
environment, hard diffusion
limiting processes, and/or
electrode surface areas being
too large for the application.
Disconnect probe. Corrosion
values should return to baseline
levels.
Another possible cause may be
due to an asymmetrical
response of the electrodes, for
example due to crevice
corrosion occurring on one of
the electrodes. The electrodes
should be inspected in this
case.
All the variables (corrosion rate,
Pitting Factor, B value and CMI)
are suspect and could be in
error. Consult with the factory
for additional information.
Check with test cell, transmitter
should give a standard
response.
Electrode surface area could be

7.1
Overview
The XYR 6000 SmartCET corrosion transmitter outputs four corrosion measurements.
•
General Corrosion Rate - average or general corrosion rate, and is generally expressed in mils per year
(mpy) or millimeters per year (mmpy).
•
Pitting Factor - dimensionless number that indicates the presence of a pitting (localization) corrosion
environment.
•
B value - expressed in millivolts per decade, and is commonly also known as the Stern Geary constant.
•
Corrosion Mechanism Indicator – indicator representing health of the probe in regard to fouling or
wear.
The values are all updated every 30 seconds, which is the total measurement cycle time of the instrument.
The values for the General Corrosion Rate, the Pitting Factor and the Corrosion Mechanism Indicator are
set to output the most recent values.
7.2
General corrosion rate
The Linear Polarization Resistance (LPR) technique is used to calculate the General Corrosion Rate. This
calculation is usually the prime variable of interest since it reflects the overall rate of metallic corrosion.
Corrosion may be directly related to operational parameters such as temperatures, flow, chemical
composition, etc.
The XYR 6000 SmartCET uses three electrodes that are referred to as the working, counter and reference
electrodes. A low frequency sinusoidal voltage excitation is applied to the working electrode with respect
to the reference electrode, and the current is measured and analyzed (on the counter electrode)
synchronously with the applied signal.
Given a sinusoidal pattern, the working electrode becomes positively charged and then negatively charged
(in other words, polarized positively and negatively). It is a DC voltage applied in a sinusoidal pattern and
resembles an AC pattern. The peak-to-peak value of the sinusoidal wave is 50mV.
Strictly, this is a measurement of the real part of the low frequency impedance of the working electrode.
This method of analysis is selected due to its superior noise rejection, which is particularly useful when
studying corroding systems since they exhibit varying degrees of intrinsic noise. The result is equivalent to
measuring the linear polarization resistance of the working electrode. With this measurement, the corrosion
current (hence, the corrosion rate) is inversely proportional to the polarization resistance.
This measurement also employs the Stern-Geary approximation where the Stern-Geary constant (or B
value) is the proportionality constant. In practice, with no prior knowledge of the system, the “default”
value of B for this type of measurement is typically chosen to be in the range 25 to 30 mV; in reality, the
value of B is system-dependent.
Use of the default B value may result in the absolute corrosion rate being somewhat in error, but in some
instances, it is the general trend of the corrosion rate that could be of interest instead of the absolute value.
Working method summary
There are three electrodes in use, which are designated working electrode (WE), counter electrode (CE)
and reference electrode (RE). A sinusoidal DC voltage is applied on the WE (voltage is varied).

7. Corrosion measurements
7.3. B value
In turn, the current response is measured between the CE and WE. The ratio of voltage to current provides
the polarization resistance. The polarization resistance is not a true resistance in the traditional sense, but
can be treated as such in describing the LPR technology.
The corrosion current is inversely proportional to the polarization resistance. How does an electrical
model represent a corrosion process? What makes corrosion look like an electrical system?
Corrosion comprises an anodic process and a cathodic process, i.e. electrochemical processes that occur at
anodic and cathodic sites on the metal surface. When corrosion is occurring, there is an increase of ionic
flow between the anodic and cathodic sites (i.e. Faradaic process). A non-corrosive system would not
exhibit any ionic flow.
Table 15 shows the relationship between corrosion rate, environment characterization and the
recommendation for getting accurate General Corrosion Rate measurements.

Comments

This could be at upper level of XYR 6000 accuracy
range. If used in this environment, electrodes with small

Use correct probe type according to process application.

Low conductivity or passive

Electrodes with large area should be used (for example,

<0.01mpy
Extreme passivity or low
conductivity (for example,
organic medium)
This could be at lower level of XYR 6000 accuracy
range. If used in this environment, electrodes with large
area should be used (for example, 10cm2).
7.3
B value
The B value represents a correction factor ‘constant’ that is determined by the mechanism and kinetics of
the corrosion process. In a dynamic process, research has shown that the B value is not constant. For
example, the B value for a sour system with a microbiological influence on corrosion activity could be
4mV. The average “industry-accepted” default B value is typically between 25 and 30mV. Houston tap
water gives a B value of 15mV. A severely scaled system (i.e. inorganic scale deposits on the metal
surface) would show a B value of around 100 mV.
By evaluation of the non-linearities in the current response from the LPR measurement, it is possible to
determine a B value for the system being studied. This involves the analysis of the higher order harmonic
content of the current response, and computation of a value of B for the system being studied.
With knowledge of the B value it is possible to refine the LPR-generated corrosion rate estimate, since the
uncertainty regarding the standard (default) B value is removed. The B value is directly related to the
mechanistic properties of the component anodic and cathodic corrosion processes.
The anodic process is essentially the metal oxidation and the cathodic process is, for example, the oxygen
reduction or hydrogen evolution. These are essentially non-linear processes, and the current will typically
(but not always) have a logarithmic dependence on the applied voltage.
The B value is a composite of the individual anodic and cathodic Tafel slopes.

The B value is calculated using the following equation: B = ba*bc/2.303*(ba+bc)
So these individual slopes are representative of non-linear processes. In the calculation of the general
corrosion rate, the B value approximation assumes that the processes are essentially linear for a small
applied potential, for example: 10 – 20 mV away from the corrosion potential and only takes into account
the first order (linear) processes. The harmonic distortion analysis takes into account the second and third
order processes, i.e. it is similar to fitting a polynomial to x3, but we use the higher frequency harmonic
components to analyze rather than trying to fit a polynomial – it’s a much better analysis route.
XYR 6000 SmartCET uses Harmonic Distortion Analysis (HDA) to calculate the ‘true’ B value. With an
accurately computed B value, the default B value used in the LPR calculation can be changed thus
enabling a more accurate corrosion rate calculation to be made.

Pitting factor
The Pitting Factor is a measure of the overall stability of the corrosion process, and is obtained from a
measurement of the intrinsic current noise of the working electrode, and comparing this measurement to
the general corrosion current obtained from the LPR measurement (for example, general corrosion rate
calculation).

7.5. Corrosion mechanism indicator
General corrosion processes typically have low levels of intrinsic noise, with the ratio of noise to the
general corrosion current typically being ≤1% (Pitting Factor ≤0.01). With the onset of instability (pit
initiation), localized corrosion occurrence leads to increasingly higher levels of current noise with respect
to the general corrosion current such that the Pitting Factor may reach a value of 1. The Pitting Factor can
be viewed as the probability that the corrosion mechanism is localized.
Spontaneous changes in the environment may also cause the instantaneous value of the Pitting Factor to
approach a value of 1 in the short term; however, for localized corrosion, the Pitting Factor will remain
unstable and secondary evidence may be observed in terms of the overall stabilities of both the general
corrosion rate estimate and the B value.
XYR 6000 uses electrochemical noise (ECN) to calculate the Pitting Factor.
A useful analogy to explain the difference between general corrosion and localized corrosion (Pitting
Factor) is that of a flashlight with its beam constantly ON (general corrosion) and one that is flickering
(localized corrosion).

Corrosion mechanism indicator
The metallic corroding interface is complex and dynamic. The general corrosion rate, the B value, and the
Pitting Factor all help to characterize the Faradaic corrosion processes (current flow that is the result of
electrochemical process) quite thoroughly. However, in order to be more complete in the analysis of the
electrochemical response there is at least one more factor which needs to be taken into account.
During the measurement of the low frequency impedance, a reactive, phase shifted component of the
current response may be detected. This is a consequence of the physical nature of the metal/environment
(electrolyte) interface, and may reflect mechanistic properties such as the presence of films, film formation
and surface adsorption processes.
The values obtained are likely to be characteristic of a particular system being studied. For example sulfide
filming may cause the reactance to become more positive, whereas adsorption processes may cause the
values to go negative. The absolute values obtained may provide the corrosion expert with extra
knowledge regarding the corrosion behavior of any particular system.
Understanding CMI values
The CMI is a qualitative indicator of whether a surface film is present or not. If there is no film and only
corrosion is present, the CMI will have an intermediate value. Inorganic scale, or thick passive oxide films
with little or no conductivity, will show a low CMI value.
Analysis of the Corrosion Mechanism Indicator is shown in Table 18.
