Linearity

Non-linearity

Hysteresis

Repeatability

Repeat accuracy

Non-linearity is the maximum deviation from a straight line which

connects the null point of the measuring range with the end point

(full scale). There is a linear relationship between the position or

stroke to be measured and the output signal for a voltage, cur-

rent or digitized information. The linearity curve of magnetostrictive

transducers does not change during the life of the system. The curve

however can be corrected.

Hysteresis is the signal difference resulting when arriving at a certain

position, traveling beyond it and then returning to this position from

the other direction.

Repeatability is moving to a certain position from both directions.

Repeatability is the sum of the hysteresis and the resolution.

The characteristic curve describes the relationship between the

output signal and the input signal. The slope of the curve represents

the sensitivity of the device.

The sensitivity (resolution) is the quotient of the input signal change

and the change in the output signal. On Micropulse transducers, the

input signal change is the change in the position of the magnet and

the output signal change is the change in the electrical output signal.

A measuring device has a linear characteristic curve and a constant

sensitivity when the relationship between the input and output

variable is represented by a straight line (linear function). Linear

scales are assumed for the X and Y-axes. A characteristic curve is

not linear if it is not a straight line.

Repeat accuracy is the value resulting when moving to the same po-

sition from the same direction under unchanging ambient conditions.

Basic Information

Deﬁ nitions

SYNC mode

Incremental

Absolute

The absolute positioning information of the displacement system is

established and transmitted synchronously to the read cycle of the

processing electronics, e.g. an axis controller or a regulating control-

ler.

Temperature coefﬁ cient

The temperature coefﬁ cient is the relative change of a physical

quantity with changing temperature. The temperature dependence

of a physical quantity y can be approximated at least for a limited

temperature range by using the temperature coefﬁ cient α with a

linear relationship y = y0 (1 + α *ΔT).

The temperature coefﬁ cient indicates the relative change in length as

temperature changes. This means that temperature factors change

the output value by the indicated amount.

Null point The null point is the position with the lowest output value along the

measuring range. For some transducer models the null point can be

set by the user. The null point must lie within the measuring range.

Sampling rate The sampling rate is the frequency at which the output information

is updated. It can be the same as the number of measurements

per second. A high sampling rate for rapidly changing positions is

important when the process is time-critical.

Nominal stroke The nominal stroke is the usable area along the transducer, and is

represented by the length indication in the part number (see also

Characteristic curve). The nominal stroke is always shorter than the

overall length of the transducer.

Damping zone The damping zone is the area in which the second (undesired)

magnetostrictive wave is damped. This area is always outside of the

measuring range. Depending on the transducer model, either an

erroneous output signal or an error signal will be output if the magnet

is allowed to travel into this zone, which must not be considered

valid information.

Temperature coefﬁ cient,

formula

After the system is switched off, the measured value currently avail-

able is not retained. A reference run to a deﬁ ned point is necessary

in order to obtain a position value. The position value is calculated by

adding or subtracting single identical increments from the reference

point.

The measured value for the current position is available immediately

after the system is switched on. An absolute coded digital signal

or an analog value is assigned to each position, e.g. along a wave-

guide. A reference run is not required.

Intrinsically safe "i"

Coding "Ex i"

Parts which could ignite a potentially explosive atmosphere must be

housed in an enclosure:

– which in case of an explosion of an explosive mixture inside the

housing can contain the pressure, and

– which prevents the internal explosion from igniting the atmosphere

surrounding the enclosure.

Protection type "n"

designation "Ex n"

Devices in these categories are intended for use in areas where an

explosive atmosphere is not expected. Even if the atmosphere were

to become explosive, in all probability it would be infrequent and only

for a short space of time.

A manufacturer's certiﬁ cate is provided, conﬁ rming that the product

satisﬁ es requirements for the use of electrical equipment in poten-

tially explosive areas according to EN 60079-15.

Several methods of ﬂ ameprooﬁ ng are combined under the designa-

tion.

e1 type approval The e1 type approval is granted by the German Federal Motor

Transport Authority KBA and conﬁ rms that special motor vehicle

standards have been maintained.

The devices may be mounted on vehicles which travel on public

roads. The standards describe EMC conditions under which

the devices must operate without failure. e1 approved Micropulse

transducers are indicated by "-SA265-" in the Part number.

The FDA (Food and Drug Administration) oversees the US food and

pharmaceutical industry and certiﬁ es devices, materials, systems

and machines from these sectors. A product designation of this kind

makes your system eligible for FDA approval.

FDA

A circuit is intrinsically safe if it does not permit a spark or thermal

effect which could ignite an explosive atmosphere as deﬁ ned by

Group IIA, IIB or IIC, whereby the test conditions prescribed in the

standard must be applied. The test conditions take into account

normal operation and certain fault conditions.

The implementation of intrinsically-safe circuits results in certain re-

strictions pertaining to the selection of components for the electrical

and electronic circuits.

In addition the permissible load on the components as compared

with normal industrial applications must be reduced:

– with respect to the voltage in terms of dielectric strength, and

– with respect to the current in terms of thermal effects.

Flameproof enclosure "d"

Designation "Ex d"

■ www.balluff.com 21

The measuring element ("waveguide") consists of a special nickel-

iron alloy with 0.7 mm outer and 0.5 mm inner diameter. A copper

conductor is introduced through the length of this tube. A short

current pulse initiates the measurement process. This current gener-

ates a circular magnetic ﬁ eld which rotates around the waveguide.

A permanent magnet at the point of measurement is used as the

marker element, whose lines of ﬁ eld run at right angles to the elec-

tromagnetic ﬁ eld.

In the area on the waveguide where the two ﬁ elds intersect,

a magnetostrictive effect causes an elastic deformation of the wave-

guide (in the microrange), which propagates along the waveguide in

both directions in the form of a mechanical wave.

The propagation velocity of this wave in the waveguide is 2830 m/s,

and is almost completely insensitive to environmental effects such as

temperature, shock and contamination.

The component of the wave which reaches the far end of the

waveguide is damped, whereas the component which arrives at the

signal converter is changed into an electrical signal by reversing the

magnetostrictive effect. The time the wave takes to travel from its

point of origin to the signal converter is directly proportional to the

distance between the permanent magnet and the signal converter.

A time measurement then allows this distance to be calculated with

extreme accuracy.

Principles of operation

MICROPULSE

Basic Information and Deﬁ nitions

Form factors

Rod housings Rod housings are mainly used in hydraulic drive applications. When

installed in the pressure section of the hydraulic cylinder, the distance

sensor requires the same pressure rating as the actual hydraulic

cylinder. In practice, the sensor must be able

to withstand pressures up to 1000 bar. The electronics are inte-

grated in an aluminum or stainless steel housing and the waveguide

in a pressure-resistant tube made from nonmagnetic stainless steel

that is sealed off at the face end with a welded plug. An O-ring seal

in the ﬂ ange at the opposite end seals off the high-pressure section.

An magnet ring with magnets slides over the tube or rod with internal

waveguide to mark the position prior to detection.

Proﬁ le housings The electronics and waveguide are enclosed in an aluminum proﬁ led

housing. The aluminum housing is hermetically sealed according to

degree of protection IP67. The magnets on the magnet act on the

waveguide through the wall of the aluminum proﬁ le.

There are two different versions of magnet, namely captive and free

magnets. Free magnets are secured directly on the moving machine

part and move with the part above and along the proﬁ le at a certain

distance. The advantage is that guide precision is not an issue with

this type of sensor. The sensors tolerate a lateral and upward offset

of several millimeters. If these generous tolerances are exceeded,

you can always revert to using captive magnets. With captive

magnets, the proﬁ le housing of the distance sensor acts as a sliding

rail along which the magnet travels. In this case, a control arm with

spherical heads compensates for unparallel movements.

Explosion-proof

versions

Many applications require the use of distance sensors in potentially

explosive areas. Flameproof magnetostrictive Micropulse transduc-

ers are available in a wide range of designs for use in zone 0 and 1.

Magnetostrictive distance sensors are ideal for applications requir-

ing a high degree of safety or availability. The sensors often have a

2-way or even 3-way redundant design in order to ensure mutual

monitoring or provide a reserve channel when required. A distance

sensor with a redundant 3-way design incorporates 3 adjacent

waveguides offset by 120°C and housed in a collective outer

tube along which an magnet moves in much the same way as on

standard housings. The magnets on the magnet act on all three

waveguides simultaneously. The three positions are evaluated by

three interdependent, completely separate electronics modules

that can be integrated in the same housing. Application examples

include ship propulsion drives, power stations and tilting technology

in trains.

Redundancy increases safety

■ www.balluff.com 23

The magnetostrictive working principle is also ideal for the continu-

ous high-precision measurement of ﬂ uid ﬁ lling levels. Waveguides

and processing electronics are enclosed inside a housing made from

stainless steel. Stainless steel ﬂ oats with permanent integrated mag-

nets mark the current ﬁ lling level in the tank or vessel. The design of

the sensors meets international hygiene standards.

MICROPULSE

Analog

voltage output

The output voltage is

directly proportional to the

position of the magnet

along the waveguide.

The most important

parameter for analog

outputs is the refresh rate

and the ripple of the

output signal. Many trans-

ducers on the market

attain the speciﬁ ed values

for output ripple only by

means of low-pass ﬁ lter-

ing. This always carries

with it an undesirable time

delay of the output signal.

Micropulse transducers

attain the speciﬁ ed signal

quality without low-pass

ﬁ lters, instead using an

improved circuit design.

This means fast update

times with low levels of

ripple and noise on the

output signal.

Micropulse transducers

with voltage output have

2 outputs, one rising and

one falling.

Available versions include:

0...10 V (10...0 V) and

–10...10 V (10...–10 V).

See technical data on

page 32

Analog

current output

The output current is

directly proportional to the

position of the magnet

along the waveguide.

Analog current interfaces

of 0...20 mA and

4...20 mA are standard

in numerous applications

and in many industries.

Current interfaces are

signiﬁ cantly less sensitive

to induced noise voltage

than analog voltage inter-

faces. A 500 Ω resistor

can be used to convert

the 0...20 mA signal into

a voltage of 0...10 V.

The 4...20 mA signal

provides a simple form of

cable break monitoring,

since a current of 4 mA

must ﬂ ow even at the

null point of the stroke.

Micropulse transducers

with current output are

available with rising or

falling signals.

See technical data on

page 32

Pulse interface

The time between an

interrogation and the

reply signal is directly pro-

portional to the position

of the magnet along the

waveguide.

These pulses are trans-

mitted using RS485/422

differential line drivers,

guaranteeing noise-free

signal transmission

over distances of up to

500 m.

The great advantage

of these interfaces is the

noise-immune signal

transmission with a

simple and economical

interface. Interfaces with

tristate outputs allow

multiplexing of several

Micropulse transducers.

Appropriate control cards

are available.

See technical data on

page 34

Synchronous serial

SSI interface

The position of the

magnet along the

waveguide is sent to the

controller serially in a

data word.

Micropulse transducers

with SSI interface can

be connected directly

to controllers or to axis

control cards with SSI

interface. The transmis-

sion of data from the

sensor to the controller is

synchronized by a clock

pulse from the controller.

Transducers with 16, 24

or 25-bit data words are

available depending on

the required resolution.

The maximum non-linear-

ity of the SSI Micropulse

transducer of ±30 µm

over the entire stroke, the

update frequency of

5 kHz and a resolution of

1 µm make SSI Micro-

pulse transducers an

ideal feedback sensor –

even in the most de-

manding positioning and

control applications.

CANopen

The position of the

magnet along the wave-

guide is sent over the

CAN bus to the controller

in so-called Process Data

Objects or PDOs.

Micropulse transduc-

ers work with standard

CANopen protocols as

per CiA DS 301 and

with the standard device

proﬁ le as per DS406.

CANopen offers greater

ﬂ exibility because of the

large number of con-

ﬁ guration options for the

transducer.

For example, the

resolution is program-

mable for 5, 10, 20 or

100 µm – depending on

your application. Alter-

natively you can select

whether both position

and velocity information

are sent to your controller.

Cyclically or on-demand.

And there's more:

Up to 4 so-called

software cams can be

deﬁ ned in the active mea-

suring range. Each time

of these cams changes,

DeviceNet

DeviceNet is a ﬁ eldbus

network which permits

communication between

basic sensors/actuators

as well as programmable

logic controllers.

Micropulse transducers

transmit the absolute

position and the velocity

to the controller in the

form of a 4 byte value

with a maximum cycle

time of 1 ms.

The communication pa-

rameters and the objects

available to the Micro-

pulse transducer can be

parameterized using the

electronic device data

sheet (EDS ﬁ le).

See technical data on

page 40

Bus interface modules

WAGO/Phoenix Contact

One ﬂ exible way of

connecting Micropulse

transducers to various

bus systems is to use

the interface modules

available from WAGO and

Phoenix Contact. These

provide the option of

transmitting the position-

ing information from sev-

eral transducers through

a single bus interface to

the supervisory controller

within a single bus cycle.

The resolution and the

null point of the transduc-

ers with the pulse inter-

face can be programmed

through the respective

bus interface. For further

technical data and

ordering bus interface

modules, contact WAGO

and Phoenix Contact.

page 162

PROFIBUS-DP

The Process Data Unit

sends position and veloc-

ity information for the

transducer to the control-

ler via the PROFIBUS-DP.

Micropulse transducers

operate according

to EN 50170 and sup-

port the PROFIBUS-DP

encoder proﬁ le as well as

multi-magnet operation.

Micropulse transducers

can be parameterized

using the GSD ﬁ le. The

position resolution can be

conﬁ gured in 5 µm incre-

ments and the velocity

resolution in increments

of 0.1 mm/s.

Working ranges and the

null point can be conﬁ g-

ured individually for each

magnet.

VARAN bus

VARAN is an open

realtime Ethernet bus

system. Micropulse AT

VARAN linear displace-

ment systems detect

the movements of highly

dynamic axes in complex

applications.

The realtime Ethernet

system is extremely

economical, easy to

implement and simple

to program. Widely

available on the market,

VARAN networks are

used in combination with

Sigmatek controllers, for

example.

VARAN is fully integrated

in hardware and designed

according to IEEE 802.3

for standard Ethernet

physics.

The simple design

guarantees extremely

rapid cycle times while

achieving maximum data

security and reducing

implementation costs.

Basic Information and Deﬁ nitions

Quality and service

HALT tests were designed to detect weaknesses early during

the product development phase and eliminate them

The result is linear displacement systems and sensors of the highest

quality and reliability which will continue to perform with the same

safety and precision for years to come. The tests reduce equipment

downtimes, prevent service and repair costs and achieve signiﬁ -

cantly greater efﬁ ciency. Rapid temperature cycles from –100 °C to

+200 °C and vibration loads between 10 °C and 50 °C can simulate

aging of a sensor. This procedure is used to test the speciﬁ cations

of products to determine the degree of reliability, load capacity and

life expectancy of the sensor. The sample is intentionally destroyed

so that we can immediately improve the ﬁ rst component to fail. Both

sensors and transducers can be tested in the HALT system.
