1 Traction monitoring: rotational speed acquisition 2 Automatic train protection: acquisition of the speed 3 i Bogie monitoring: rotational speed, acceleration and temperature measurement 4 Wheel slide protection: rotational speed acquisition for brake control Rail vehicles are subject to extreme environmental conditions 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 effects . For decades...

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 elements 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...

Speed sensors with up to four channels Tailor-made for your application Sometimes the mounting positions of the sensor and target wheel require a specific position for the active elements 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 applications such as the EEx area, SIL applications or UIC requirements. We harmonise all the necessary...

One sensor for up to four control units Up to four individually arranged sensor elements are integrated into a standard housing in the multichannel sensor. Optionally, we deliver systems with a dedicated power supply and electrically decoupled . The multichannel sensors output different signals on up to four independent channels . If necessary, a fixed phase relationship can be generated between two channels . The output of a standstill voltage, as required by brake control systems, is also available . We will prepare an individual multichannel sensor for you, please state the following...

Speed sensors with up to four channels Technical data Output signals EC = eddy current technique; Al = aluminium; VA = stainless steel; UIC = as per UIC certificate B-004/2011-04; ATEX = sensor for the EEx area available Advantages of our speed sensors for railway rolling stock: • Withstand high shock and vibration loads due to encapsulated electronics • Withstand dust and water and meet the requirements of protection class IP 68 according to DIN EN 60529 • Operate reliably at temperatures from -40 °C to +120 °C • Meet the EMC requirements of EN 50121-3-2 • They are extremely compact and...

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 realtime regulation. Here rotary encoders with integrated bearings 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....

Incremental rotary encoders and axle encoders Measuring systems for high loads Withstanding extreme weather conditions Extreme shaft loads often occur in railway rolling stock. For this specific case we offer precision speed sensors with a special coupling. All rotary encoders provide exact measured values even with changing ambient temperature, fluctuations in humidity, heavy vibration, and condensation. The integrated, flexible hollow shaft coupling with a diameter of 20 mm also permits mounting on motors with high axial and radial shaft motion. Alternatively the rotary encoder is...

Temperature sensors and CombiCODERsClever 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 according 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...

The right target wheel for every speed sensorPrecisely 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...
