Developed for usage in rail vehicles

Sensors from lenord + Bauer – on the move worldwide for decades

Rail vehicles are subject to extreme environmental condi-

tions . They operate in wind and weather in all regions of

the earth . Above all the running gear must withstand heat,

cold, large temperature changes, wet, high atmospheric

humidity, dust and stone impacts .

Sensors mounted here are subjected directly to these ef-

fects . For decades our resilient products have been proven

in operation all over the world . We deliver ready-to-connect

systems for the acquisition of rotational speed, tempera-

ture or acceleration .

Our product program ranges from maintenance and wear-

free speed and temperature sensors, through individual

multichannel sensors and CombiCODERs, to high-resolu-

tion, incremental rotary encoders and axle encoders . We

also deliver target wheels ex-works on short delivery

times .

High availability and the stable function of the sensors are

crucial factors for our customers . These aspects are the re-

sult of our quality policy . We are certified according to IRIS,

DIN EN ISO 9001 and ISO 14001 . Our products for railway

rolling stock meet all common requirements such as UIC,

EN 50155 and IEC 61373 as well as EN 50121-2-3 .

2 Automatic train protection: acquisition of the speed

3 Bogie monitoring: rotational speed, acceleration and temperature measurement

4 Wheel slide protection: rotational speed acquisition for brake control

Speed sensors with up to four channels

Speed sensors with up to four channels

customised acquisition of rotational speed and speed

Speed sensors acquire the smallest movements from 0 Hz

just as reliably as they acquire fast rotations at up to

25 kHz . They are entirely maintenance and wear-free, as

they operate without contact .

Magnetic sensors with proven technology

A sensor that comprises a permanent magnet and Hall ele-

ments scans a ferromagnetic target wheel . The magnetic

field in the sensor changes due to the rotating tooth wheel

and modulates the Hall voltage .

The electronics convert the modulated voltage into square-

wave signals . Here the signal frequency is directly propor-

tional to the rotational speed of the shaft . This measuring

technique has been proven for decades in rail vehicles

worldwide .

lightweight design thanks to eddy current principle

On the other hand, with the eddy current technique the

eddy currents induced by the measuring scale are acquired

by secondary coils . The target wheels used are made of an

electrically conductive material such as steel or alumini-

um . The weight-saving design is a real advantage . In addi-

tion, the sensor is ideal for use in environments containing

iron . As the sensor does not attract any magnetic particles

such as iron chips or dust .

The solution for numerous tasks

Our speed sensors output the signals on up to four chan-

nels . By means of electrical isolation the sensor can pro-

vide independent signals for several control units . If it also

outputs a fixed voltage, the control system can detect

standstill .

The direction of rotation of the target wheel is acquired ei-

ther via a directional signal or the evaluation of two chan-

nels with 90° phase offset . Here an index pin in the flange

ensures the correct assignment of the channels to the di-

rection of rotation .

resistant to interference fields

The inversion of the signals reduces the effect of coupled

interference signals . As the control system evaluates the

voltage difference between the signal and the inverted sig-

nal . In this way it obtains stable measured values even

with long connection cables or strong interference fields .

Sensors with current output are more suitable for usage in

extreme electromagnetic interference fields as current sig-

nals are less susceptible to electromagnetic fields . A posi-

tive side effect: the control system detects a wire break

without additional function monitoring .

Speed sensors with up to four channels

Tailor-made for your application

Sometimes the mounting positions of the sensor and tar-

get wheel require a specific position for the active ele-

ments in the sensor tip . In this case we position the sensor

elements to suit your requirements .

We also realise special functions for our customers . Tell us

your requirement and we will integrate, for example, pulse

division or a self-test into the electronics .

Upon request we manufacture products for special appli-

cations such as the EEx area, SIL applications or UIC re-

quirements . We harmonise all the necessary components .

optimally exploiting the limited installation space

High quality monitoring systems ensure more safety dur-

ing operation . Here the individual systems require very dif-

ferent signals . As a consequence the number of sensors

required increases .

Anyone who needs to acquire an increasing number of

measured parameters on the running gear will find an ap-

propriate solution with our multichannel sensors . Up to

four sensor systems are integrated into one standard

housing . As such they provide signals for a maximum of

four control units .

incremental rotary encoders and axle encoders

incremental rotary encoders and axle encoders

Tailored robust encoder systems for extreme conditions

Precise measured values are required these days for real-

time regulation . Here rotary encoders with integrated bear-

ings are used . It is typical for these measuring systems

that the scanning unit and target wheel are integrated into

one housing . Both components are exactly matched .

With pulse numbers of up to 10,000 increments per turn,

the encoders cover all measuring ranges in the vehicle and

have been proven for decades in railway rolling stock .

Magnetic incremental rotary encoders

Our magnetic incremental encoders acquire the an-

gular change on a rotating shaft . The integrated sen-

sors contactlessly scan a target wheel installed in

the housing .

The magnetic sensor provides 1-Vpp differential

signals and HTL or TTL signals . It is possible to

derive from the signals generated the direc-

tion of rotation, the distance covered and

the speed of the rotating shaft .

one axle encoder – many output signals

For wheel slide protection, train protection and ancillary

applications on the bogie we offer special multichannel

axle encoders . They provide different signals for several

control systems and therefore exploit their full potential .

The sensors provide independent square-wave signals on

up to eight channels . These signals are output by the inte-

grated push-pull electronics with up to three different

pulse numbers . Output takes place either in voltage or

current levels .

The channels can be configured and output individually

or in groups with fixed phase relationship . In this way

the characteristics of the output signals can be

matched exactly to the control units . As such you ob-

tain a solution individually tailored to the applica-

tion .

incremental rotary encoders and axle encoders

Measuring systems for high loads

Extreme shaft loads often occur in railway rolling stock . For

this specific case we offer precision speed sensors with a

special coupling .

The integrated, flexible hollow shaft coupling with a diam-

eter of 20 mm also permits mounting on motors with high

axial and radial shaft motion . Alternatively the rotary en-

coder is available with a 16 mm solid shaft .

Up to 5 independent, fully encapsulated sensor modules

can be positioned in a stainless steel housing . We individ-

ually adapt each module to your application and the con-

trol system . As such the system is of versatile application .

Withstanding extreme weather conditions

All rotary encoders provide exact measured values even

with changing ambient temperature, fluctuations in hu-

midity, heavy vibration, and condensation .

Additional protection measures can be selected for special

environmental effects, for instance protective lacquers or a

condensation drain . Talk to us .

Temperature sensors and combicoDers

Temperature sensors and combicoDers

clever solution - the acquisition of temperature, shock and rotational speed

Temperature acquisition with minimal effort

In motors and bearings the temperature is a parameter

that is often monitored to detect uneconomical or even

critical states at an early stage . Our temperature sensors

are used here .

Compact, robust platinum resistance thermocouples ac-

cording to DIN EN 60751 form the basis for these sensors .

The sensors are checked according to EN 50155 and meet

protection class IP 68 . The length of the stainless steel

sensor tube is adapted to the related installation situation .

If necessary, we also manufacture the flange to customer

requirements .

If temperature and rotational speed in the drive motor are

required, we combine the temperature sensor with any

speed sensor using a cable harness . The connection via a

common connector significantly reduces installation effort .

Three systems in one housing

Due to limited installation space it is often necessary to

combine several sensor types in one system . Our Com-

biCODERs provide the perfect solution here .

On the CombiCODER we integrate speed, temperature and

vibration sensors in one housing . In this way these sensors

acquire, for instance, the vibration behaviour on the bogie

and the temperature in the bearing . We combine the com-

ponents individually to suit your requirements and adapt

the shape as necessary .

The installation and maintenance effort is also significant-

ly reduced by using CombiCODERs . Where up to now, three

to four different sensors had to be installed, now only one

sensor needs to be installed and tested .

The right target wheel for every speed sensor

The right target wheel for every speed sensor

Precisely manufactured and individually adapted to your needs

For the measurement of rotary movements, speed sensors

form a unit together with target wheels . To obtain optimal

output signals, target wheels must be manufactured with

high precision . Only in this way can the output signals from

the sensors be generated with the necessary quality .

We deliver standard ferromagnetic target wheels ex-works

on short delivery times . They are suitable for attachment to

shafts with a diameter from 8 mm to over 500 mm . Size,

inside diameter and design of the target wheel define the

strength and the maximum permitted rotational speed .

In your enquiry please state the maximum rotational speed

at which the target wheel is to be used . We will then evalu-

ate the application and also undertake a calculation using

FEM in special cases .

The perfect unit: target wheel and sensor

• Target wheel matched to your sensor with individual inside diameter

• Quicker, more straightforward installation due to complete manufacture with bores, threads, feather keyways etc .

• High flexibility in assembly

• Optimal prevention of twisting in relation to the shaft possible using feather keyway

• The target wheel can be used as a bearing cover or shaft nut

� Characteristics in accordance with UIC specification

� Characteristics in accordance with UL/CSA specification

Tell us about your requirements and we will agree with you

the right material .

Guarantor for high reliability

Reliability and long availability characterise modern com-

ponents for rail vehicles . For this reason we place particu-

larly high value on high quality components and continu-

ous quality control . Therefore final testing is a fixed

element of our production .

Among other features we test the current consumption of

the sensor as well as the level, position and load capacity

of the output signals . For each individual product we save

the measured values and document all the data from the

final test . If required we prepare a product test certificate .

Qualified, railway sensor technology

For our railway-specific sensors we undertake a type test in

accordance with EN 50155 and in this way ensure the re-

quired stable function of the electronics .

For some applications the aspects defined in the standard

are inadequate . In this case we prepare individual test pro-

cedures with you . In the end you receive a measuring sys-

tem qualified to your requirements .

We offer you individual, durable sensor systems ready to connect . challenge us!

applications

Sensors for safe operation

for decades our systems have been proven in many applications

On accelerating several thousand tons of weight, the con-

trol of the physical forces presents a technical challenge .

Today modern drive, brake and train protection systems

aid the train driver .

These systems must operate reliably in wind and weather .

Some components are directly subjected to the weather,

as well as impacts from stones and dust . Above all the sen-

sors must be resilient as they are mostly mounted on the

running gear, for example on the motor, on the wheel sets

or on the ends of the axles .

For this reason the electronic components in our sensors

are protected against extreme weather conditions, humid-

ity, shock and vibration by special manufacturing meth-

ods . Our long-lasting systems have been proven in rail ve-

hicles for decades .

We cover a broad range of sensor products for railway roll-

ing stock . Mostly we supply individual systems that we

have developed for an application in cooperation with our

customers .

common application areas

On the following pages we will show you our solutions for

the following railway applications:

• Rotational speed acquisition for drive control and traction monitoring

• Acquisition of the speed for automatic train protection

• Rotational speed, acceleration and temperature measurement for monitoring the bogie

• Rotational speed acquisition for brake control in wheel slide protection systems

Traction monitoring

14

applications

Traction monitoring

rotational speed acquisition

When modern trains are set in motion, the vehicles drive

up to 3,000 tons inertial mass, depending on train type . To

prevent the wheel sets from spinning, the drives are con-

trolled by intelligent control systems . They synchronise the

output of motors and distribute the power evenly between

the axles .

The inverters require reliable rotational speed signals for

the drive control . For this purpose, sensors monitoring the

rotational speed and direction of rotation of the drive are

installed on motor or gear . These sensors must acquire

standstill just as reliably as the achievement of maximum

speed .

robust sensors for rotational speed acquisition on the motor or gear

In many rail vehicles the speed sensors supply the meas-

ured values required . They acquire slow movements and

standstill just as reliably as fast rotational movements .

With a measuring range from 0 Hz up to 25 kHz they are

excellently suited for this task .

Alternatively our incremental rotary encoders are used for

drive control . They are characterised by high reliability

even under the most extreme shock and vibration loads .

our recommendation:

• Speed sensors

• Incremental rotary encoder

automatic train protection

15

applications

automatic train protection

acquisition of the speed

Systems for Automatic Train Protection (ATP) ensure,

among other aspects, that the speed allowed is not ex-

ceeded and the distance to the train in front is maintained .

The systems receive information on the occupation of the

section and speed limit from track-side equipment . From

the data received the ATP determines, for example, the

speed of the train . The train protection sends its own val-

ues back to the section for the trains behind .

robust incremental encoders for installation on axle

One control parameter for automatic train protection is the

speed . The system determines this parameter from the

axle revolutions per minute . The sensors used here meas-

ure the rotational speed directly at the wheel set and are

subject to extreme environmental effects, depending on

the installation position .

Our robust speed sensors and multichannel incremental

encoders (also referred to as "axle encoders") are particu-

larly suitable for continuous usage on the running gear .

They provide reliable measured values for automatic train

protection even at high loads .

our recommendation:

• Axle encoders (multichannel incremental encoders)

• Precision rotary encoders

• Speed sensors

Bogie monitoring

16

applications

Bogie monitoring

rotational speed, shock and temperature acquisition

Bogies are subjected to high physical forces . They not only

carry an enormous weight, but also braking, acceleration

and centrifugal forces act on tyres and bearings . For this

reason, continuous monitoring for the early detection of

wear and material fatigue on the running gear is of particu-

lar importance .

Technical faults can manifest themselves in various ways .

Therefore, different measuring systems are used for the

monitoring of bogies . Along with the rotational speed, e .g .

the bearing temperature is monitored .

Speed and temperature sensors for installation on the bogie

We have been manufacturing robust sensors for rotational

speed and temperature acquisition on bogies for many

years . They ensure the detection of safety-relevant events

and timely correction of malfunctions .

Based on decades of experience in railway rolling stock,

we have a very extensive range of speed sensors . The tai-

lor-made temperature sensors with tube lengths from

30 mm to 200 mm are excellently suited to bogie monitor-

ing .

A large number of installation situations can be realised by

means of different housing variants and cable outlets . In

particularly difficult cases, we adapt our standard encod-

ers to your requirements .

our recommendation:

• Speed and temperature sensors

• CombiCODER

Bogie monitoring

17

applications

Bogie monitoring

rotational speed, acceleration and temperature measurement in one housing

All rail vehicles, whether locomotive, tractive unit, train set

or goods wagon, must be operated safely and reliably even

under the harshest conditions . The requirements on mod-

ern rail vehicles have been steadily increasing in recent

decades . To ensure safe operation, the acquisition of more

and more measured parameters is required on the bogie . A

very limited installation space is in contrast to this trend .

Multifunctional sensor systems optimally exploit the limited installation space

Developed from our proven magnetic sensors for rotation-

al speed acquisition, combined systems optimally exploit

the small installation space . As such, for example, the

CombiCODERs provide rotational speed signals on up to

three channels and also acquire the vibration behaviour on

the bogie and the temperature on the bearing .

For this reason, they are ideally suited to applications with

little space . Electrically the combination sensors are con-

nected using only one coupling; this feature significantly

reduces the cabling effort .

Their usage also clearly reduces the installation and main-

tenance effort . Where up to now, three to four different

sensors had to be installed and tested, this work is now

required for only one system .

our recommendation:

• CombiCODER with - Speed sensor - Temperature sensor - Acceleration sensor

• Multifunctional axle encoders

18

applications

Wheel slide protection

rotational speed acquisition for brake control

Wheel slide protection systems are used to prevent the

blocking of wheel sets during the braking process . Similar

to ABS systems on cars, they individually control the brak-

ing force on each single axle and in this way prevent the

formation of wheel flats . In this way vibration that causes

wear on the bogie and the rails is prevented .

Wheel slide protection systems evaluate the rotational

speeds of the individual vehicle axles for exact brake con-

trol . Our speed sensors are used worldwide for this pur-

pose . Due to the installation position, they are exposed to

extreme temperatures, shock, humidity and vibration .

Speed sensors withstand the extreme environ-mental conditions

Our magnetic sensors contactlessly scan a target wheel

and therefore operate entirely wear-free . The delicate elec-

tronics are protected by encapsulation, for this reason they

withstand even the extreme environmental effects .

The recommended speed and multichannel sensors com-

ply not only with common railway standards, but also with

the conditions from the UIC for usage with common brake

control units . For this reason, they are particularly appro-

priate for applications in wheel slide protection systems .

our recommendations:

• Speed sensors

• Multichannel sensors
