Model 396PVP is offered with a watertight sensor-to-

cable connector which eliminates re-wiring and cable

twisting when replacing sensors. The Variopol VP

multiple pin connector is an integral part of each sen-

sor model and uses a mating VP cable. Once the

cable is installed and wired to the analyzer, sensors

are easily replaced without replacing the cable, and, if

the replacement sensor is the same as its predeces-

sor, without rewiring the analyzer. Also the cable can

be disconnected from the sensor before removal from

the process which eliminates cable twisting.

The entire line of TUpH model sensors now incor-

porate the new SILCORE technology contaminant

barrier. This triple-seal barrier prevents moisture and

material impurities from migrating to the pH sensor’s

reference electrode’s metal lead wire. By preventing

these contaminants from compromising the integrity

of the pH measurement, sensor life is increased,

especially at higher temperatures where increased

migrations occur. In addition, the SILCORE technolo-

gy provides added protection against sensor failure

due to vibrations and shock by transferring damaging

energy away from the glass-to-metal seal.

The AccuGLASS pH glass formulations exceed

industry standards. The AccuGlass pH glass is a

result of many years of glass research resulting in a

formulation which has been found to increase the life

of the sensor. Unlike other pH glasses presently on

the market, this glass resists cracking especially at

higher temperatures and reduces sodium ion error

commonly found in high pH applications. Overall, the

AccuGlass formulation enhances the sensor perform-

ance to measure pH more accurately and have a

longer sensor life than ever before.

DESCRIPTIONS AND SPECIFICATIONS

SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

1.1 FEATURES AND APPLICATIONS

The Rosemount Analytical Model 396P and 396PVP

Sensors measure the pH or the ORP of aqueous solu-

tions in pipelines, open tanks, or ponds. It is designed

for harsh, dirty applications such as sourwater waste

treatment and scrubbers, where a high performance,

low maintenance, disposable sensor is required.

The combination electrode features a patented, large

area polypropylene reference junction for resistance to

process coatings, generally found in dirty, high solid

applications. The patented helical reference pathway

provides added resistance for poisoning applications.

In addition, it is available in two configurations:

glass/platinum electrode completely recessed within

the reference junction for added life in abrasive or

rough applications and the glass/platinum electrode

partially exposed for added life and accuracy in vis-

cous and low flow applications.

Both Models feature a titanium solution ground con-

structed in an annular design around the pH/ORP elec-

trode. The solution ground provides glass and refer-

ence sensor diagnostics for preventative maintenance

when used with the Model 54e, 1055, 5081, 3081,

4081, 81 pH/ORP, and Xmt-P transmitters. In addition

Models 396P and 396PVP can be used with most non-

diagnostic Rosemount Analytical and other manufac-

turer’s instruments.

Each sensor is housed in a molded polypropylene

body with EPDM seals, making it virtually indestructi-

ble and chemically resistant. Complete encapsulation

eliminates leakage or high humidity problems tradi-

tionally found in other pH/ORP designs. The simplified

construction, designed with user convenience in mind,

does not require electrolyte (KCl) replenishment or any

high maintenance troubleshooting procedures.

The Model 396P is offered with or without an optional

integral preamplifier to convert the high impedance pH

or ORP mV signal into a stable, noise-free signal with

transmission capability of up to three miles. A remote

preamplifier must be used with Model 396PVP.

Installation is easily achieved through the wide variety

of mounting configurations. The Models 396P and

396PVP feature 1 in. (MNPT) front and rear facing

connections for insertion, submersion or flow through

pH and ORP applications.

INSTALLATION

SECTION 2.0

INSTALLATION

2. Do not install the sensor on the horizontal. The

sensor must be 10° off the horizontal to ensure

accuracy.

3. Do not install the sensor upside down.

4. Air bubbles may become trapped in the sensor end

between the glass bulb and the sensor body. This

problem is most commonly encountered in areas

of low flow or during calibration. Shake the probe

while immersed in solution to remove bubbles.

This problem can be avoided by ordering the sen-

sor with the slotted tip (option -41).

In most cases, the pH sensor can simply be installed

as shipped and readings with an accuracy of ± 0.6 pH

may be obtained. To obtain greater accuracy or to ver-

ify proper operation, the sensor must be calibrated as

a loop with its compatible analyzer or transmitter.

2.2.1 Flow Through and Insertion Mounting.

Model 396P and 396PVP Sensors have a 1-inch

MNPT process connection at the front of the sensor for

mounting into a 1-1/2 inch tee or the process pipes.

See Figure 2-1 through Figure 2-7 for installation con-

figurations.

NOTE

LARGE PIPE WRENCHES MUST NOT BE

USED TO TIGHTEN THE SENSOR INTO A

FLANGE OR OTHER TYPE OF MOUNTING.

2.2.2 Submersion Mounting. Model 396P and

396PVP Sensors also have a 1 inch MNPT process

connection at the back of the sensor. Utilizing a stan-

dard 1 inch union, the sensor may be mounted to a 1

inch SCH 80 CPVC or PVDF standpipe (see Figure 2-

x). Tapered pipe threads in plastic tend to loosen after

installation. It is therefore recommended that Teflon1

tape be used on the threads and that the tightness of

the connection be checked frequently to assure that no

loosening has occurred. To prevent rain water or con-

densation from running into the sensor, a weatherproof

junction box is recommended (see Figure 2-x). The

sensor cable must be run through a protective conduit

for isolation from electrical interference or physical

abuse from the process. The sensor should be installed

within 80° of vertical, with the electrode facing down.

The sensor’s cable should not be run with power or

control wiring.

2.1 UNPACKING AND INSPECTION.

Inspect the outside of the carton for any damage. If dam-

age is detected, contact the carrier immediately. Inspect

the hardware. Make sure all the items in the packing list

are present and in good condition. Notify the factory if any

part is missing. If the sensor appears to be in satisfactory

condition, proceed to Section 2.2, Mounting.

NOTE

Save the original packing cartons and materi-

als as most carriers require proof of damage

due to mishandling, etc. Also, if it is necessary

to return the sensor to the factory, you must

pack the sensor in the same manner as it was

received. Refer to Section 6.0 for return

instructions. If the sensor is to be stored, the

vinyl boot should be filled with pH buffer solu-

tion and replaced on sensor tip until ready to

use.

CAUTION

Buffer solution, in the vinyl boot, may cause

skin or eye irritation.

WARNING

Glass electrode must be wetted at all times (in

storage and in line) to maximize sensor life.

2.2 MOUNTING.

The sensor has been designed to be located in indus-

trial process environments. Temperature and pressure

limitations must not be exceeded at any time. A caution

label regarding this matter is attached to the sensor.

Please do not remove the label. See Figure 2-1.

CAUTION

Internal electrolyte fill solution may cause skin

or eye irritation.

Mounting Guidelines:

1. Shake the sensor in a downward motion to

remove any air bubbles that may be present inside

the tip of the pH glass.

Figures in this section provide the guidelines for wiring

the 396P-01 sensor to various Analyzer/Transmitter

instruments.

To determine which wiring guideline to use, locate the

model number of the sensor to be installed.

1. If the cable needs to be extended, use a high qual-

ity eleven conductor double shielded instrument

cable available from Rosemount Analytical. Refer

to Table 3-1 for the appropriate junction box to use

and the corresponding wiring details.

NOTE

If the cable is too long, loop up the excess

cable. If the cable has to be shortened, cut

and terminate each conductor neatly and

make sure that the overall (outermost)

drain wire is not shorted out with either

of the two inner drain wires (shields).

2. Signal cable should be run in a dedicated conduit

(preferably an earth grounded metallic conduit)

and should be kept away from AC power lines. For

your convenience, a wire nut kit is furnished (in a

plastic bag wrapped around the cable).

NOTE

For maximum EMI/RFI protection when

wiring from the sensor to the junction box,

the outer braid of the sensor should be con-

nected to the outer braided shield of the

extension cable. The outer braid of the

extension cable to the instrument must be

terminated at earth ground or by using an

appropriate metal cable gland fitting that

provides a secure connection to the instru-

ment cable.

1. While obtaining a process solution sample (it is recommended that

the sample is taken close to the sensor), record the pH value that

is shown on the analyzer/transmitter display.

2. Measure and record the pH of the process solution sample with

another temperature compensated, calibrated pH instrument. For

best results, standardization should be performed at the process

temperature.

3. Adjust the analyzer/transmitter value to the standardized value.

5.2 MODEL 396P and 396PVP ORP SENSORS

5.2.1 SENSOR PREPARATION. Most industrial applications have

a number of ORP reactions occurring in sequence or simultaneously.

There can be several components that are oxidized or reduced by

the reagents that are used. Theoretically, the ORP potential is

absolute because it is the result of the oxidation-reduction equilibri-

um. However, the actual measured potential is dependent on many

factors, including the condition of the surface of the ORP platinum

electrode. Therefore, the sensor should be allowed 1-2 hours to

become “conditioned” to the stream when first set-up or after

being cleaned.

5.2.2 ORP CALIBRATION

1. Make a temporary electrical connection between the sensor and

the instrument.

2. Obtain an ORP standard solution, or a standard solution can also be

made quite simply by adding a few crystals of quinhydrone to either

pH 4 or pH 7 buffer. Quinhydrone is only slightly soluble therefore a

few crystals will be required. (Refer to Section 4.3. for an alternate

ORP standard solution).

3. Immerse the sensor in the standard solution. Allow 1-2 minutes for

the ORP sensor to stabilize.

4. Adjust the standardize control of the instrument to the solution value

shown in Table 5-1 (below) or on the label of the standard solution.

The resulting potentials, measured with a clean platinum electrode

and saturated KCl/AgCl reference electrode, should be within ±20

millivolts of the value. Solution temperature must be noted to ensure

accurate interpretation of results. The ORP value of saturated quin-

hydrone solution is not stable over long periods of time. Therefore,

these standards should be made up fresh each time they are used.

5. Remove the sensor from the buffer, rinse and install in the process.

MODEL 396P and 396PVP SECTION 5.0

START UP AND CALIBRATION

SECTION 5.0

START UP AND CALIBRATION

5.1 MODELS 396P and 396PVP pH SENSORS

5.1.1 SENSOR PREPARATION.Shake down the sensor

to remove any air bubbles that may be present at the tip of

the pH glass bulb. In most cases, the pH sensor can simply

be installed as shipped and readings with an accuracy of ±

0.6 pH may be obtained. To obtain greater accuracy or to

verify proper operation, the sensor must be calibrated as a

loop with its compatible analyzer or transmitter.

5.1.2 pH CALIBRATION. After a temporary connection is

established between the sensor and the instrument, a buffer

calibration may be performed. Consult appropriate pH/ORP

analyzer or transmitter instruction manual for specific calibra-

tion and standardization procedures, or see below for recom-

mended two-point buffer calibration procedure.

Recommended two-point buffer calibration procedure:

Select two stable buffer solutions, preferably pH 4.0 and 10.0

(pH buffers other than pH 4.0 and pH 10.0 can be used as long

as the pH values are at least two pH units apart).

NOTE

A pH 7.0 buffer solution reads a mV value of approxi-

mately zero, and pH buffers read approximately 59.1

mV for each pH unit above or below pH 7.0. Check the

pH buffer manufacturer specifications for millivolt values

at various temperatures since it may affect the actual

value of the buffer solution mV/pH value.

1. Immerse sensor in the first buffer solution. Allow sensor

to adjust to the buffer temperature (to avoid errors due to

temperature differences between the buffer solution and

sensor temperature) and wait for reading to stabilize.

Value of buffer can now be acknowledged by

analyzer/transmitter.

2. Once the first buffer has been acknowledged by the ana-

lyzer/transmitter, rinse the buffer solution off of the sensor

with distilled or deionized water.

3. Repeat steps 1 and 2 using the second buffer solution.

4. Once the analyzer/transmitter has acknowledged both

buffer solutions, a sensor slope (mV/pH) is established (the

slope value can be found within the analyzer/ transmitter).

5. The slope value should read about 59.1 mV/pH for a new

sensor and will decrease over time to approximately 47-

49 mV/pH. Once the slope reads below the 47-49 mV/pH

range, a new sensor should be installed to maintain accu-

rate readings.

Recommended pH Sensor Standardization:

For maximum accuracy, the sensor can be standardized online

or with a process grab sample after a buffer calibration has

been performed and the sensor has been conditioned to the

process. Standardization accounts for the sensor junction

potential and other interferences. Standardization will not

change the sensor’s slope but will simply adjust the analyzer’s

reading to match that of the known process pH.

MAINTENANCE

The Model 396P and 396PVP Sensors require mini-

mum maintenance. The sensor should be kept clean

and free of debris and sediment at all times. The fre-

quency of cleaning by wiping or brushing with a soft

cloth or brush is determined by the nature of the solu-

tion being measured. The sensor should be removed

from the process periodically and checked in buffer

solutions.

WARNING

BEFORE REMOVING THE SENSOR, be

absolutely certain that the process pres-

sure is reduced to 0 psig and the

process temperature is lowered to a

safe level!

If the sensor will not calibrate, refer to your analyzer/

transmitter instruction manual for proper test proce-

dures. If it is determined that the sensor has failed, it

should be discarded and replaced.

6.1 AUTOMATIC TEMPERATURE

COMPENSATOR.

The temperature compensator element is temp-

erature sensitive and can be checked with an ohm-

meter. Resistance increases with temperature.

The 3K element will read 3000 ohms ± 1% at 25°C

(77°F) and a Pt100 will read 110 ohms. Resistance

varies with temperature for a 3K and Pt100 element

and can be determined according to Table 6-2 or the

following formula:

RT=Ro[l+R1(T-20)]

Where RT= Resistance

T = Temperature in °C

Refer to Table 6-1 for Roand R1values

6.2 MODEL 396P & 396PVP pH SENSORS

4.2.1 ELECTRODE CLEANING. If the electrode is

coated or dirty, clean as follows:

1. Remove the sensor from process.

2. Wipe the glass bulb with a soft, clean, lint free

cloth or tissue. If this does not remove the dirt or

coating, go to Step 3. (Detergents clean oil and

grease; acids remove scale.)

3. Wash the glass bulb in a mild detergent solution

and rinse it in clean water. If this does not clean

the glass bulb, go to Step 4.

SECTION 6.0

MAINTENANCE

CAUTION

The solution used during the following

check is an acid and should be handled

with care. Follow the directions of the acid

manufacturer. Wear the proper protective

equipment. Do not let the solution come in

contact with skin or clothing. If contact with

skin is made, immediately rinse with clean

water.

4. Wash the glass bulb in a dilute 5% hydrochloric

acid solution and rinse with clean water. Soaking

the sensor overnight in the acid solution can

improve cleaning action.

NOTE

Erroneous pH results may result immedi-

ately after acid soak, due to reference

junction potential build-up.

Replace the sensor if cleaning does not

restore sensor operation.

with care. Follow the directions of the acid

manufacturer. Wear the proper protective

equipment. If contact with skin of clothing is

made, immediately rinse with plenty of

clean water.

Type 2: A second ORP standard solution is the Ferric-

Ferrous Ammonium Sulfate Solution (PN R508-16OZ),

and it can be ordered as a spare part; otherwise, it can

be prepared from the following recipe: Dissolve 39.2

grams of reagent grade ferrous ammonium sulfate,

Fe(NH4)2(SO4)2• 6H2O and 48.2 grams of reagent

grade ferric ammonium sulfate, FeNH4(SO4)2•

12H2O, in approximately 700 milliliters of water (dis-

tilled water is preferred, but tap water is acceptable).

Slowly and carefully add 56.2 milliliters of concentrated

sulfuric acid. Add sufficient water to bring the total solu-

tion volume up to 1000 ml. This standard ORP solution,

although not as simple to prepare as the quinhydrone

recipe, is much more stable, and will maintain its milli-

volt value for approximately one year when stored in

glass containers. This solution (ferric/ferrous ammoni-

um sulfate) will produce a nominal ORP of 476 +20 mV

at 25°C when used with a saturated KCl/AgCl refer-

ence electrode and platinum measuring electrode.

Some tolerance in mV values is to be expected due to

the rather large liquid reference junction potentials

which can arise when measuring this strongly acidic

and concentrated solution. However, if the measuring

electrodes are kept clean and in good operating condi-

tion, consistently repeatable calibrations can be carried

out using this standard solution.

6.3.2 Cleaning Platinum Electrode. The electrode can

be restored to normal operation by simply cleaning the

platinum electrode with baking soda. Polish it by rubbing

it with a damp paper towel and baking soda until a bright,

shiny appearance is attained.

The Model 54 Analyzer and Models 81 and 3081 Transmitters automatically search for fault conditions that would

cause an error in the measured pH value, as does the Model 1054B pH/ORP Analyzer to a lesser degree. Refer to

the applicable Instruction Manual for a complete description of the analyzer’s fault conditions.

Table 7-1, below, lists the Model 54’s, 4081’s, 3081’s, and 81’s diagnostic messages that indicate a possible sen-

sor problem. A more complete description of the problem and a suggested remedy corresponding to each mes-

sage is also listed.
