Speed Measurement


Configurable screen sizes and rugged housings - that's what makes OEM's display computers perfect for high-demanding applications in the rail industry. The display computer is always realized without fans using conductive cooling between the electronics and the display to spread the dissipated heat to the outside of the housing. These display computers can be qualified according to the EN 50155 with a nominal input voltage of 110 VDC for railway applications.


Radar speed sensors are contactless in operation, and use the Doppler microwave principle to calculate measured values. Their integrated digital signal processor (DSP) performs the requisite evaluation algorithms within the device itself, and the speed, distance, direction, and acceleration values are then output via serial interfaces and pulse outputs. Incorporation of these intelligent sensors ensures that the vehicle control system offers the maximum degree of versatility and safety.


The hall-effect pickup sensors are distinguished by an extremely long service life thanks to their contactless and thus almost wear-free mode of operation. The measurement is taken by scanning a toothed wheel or magnetic wheel. The pickup sensor is mounted at a defined distance above the wheel.

The direction of rotation can also be determined. This is done by arranging two Hall elements within the sensor in a relative geometrical position to one other that allows the determination of both speed and rotational direction.


Axle-mounted speed sensors are driven via a mechanical coupling on the axle of the vehicle. Impervious to dirt and vibration, they are virtually maintenance-free and achieve high resolution even at low rotational speeds. The product range also includes speedometer generators. The sensors generate a voltage and frequency that is proportional to the rotational speed, which can be fed directly to a converter or indicator via a cable, without the need for an additional power supply. The electronic pulse generators (incremental encoders) are based on a variety of principles, including optical barrier photocells and Hall sensors.
