Pegasem Messtechnik GmbH
PEGASEM is specialised in high precision measurement of distance and speed of land vehicles. From these they calculate acceleration, deceleration performance and slip data utilizing real time processing. The products are designed for the harsh environments, typical in testing vehicles. Their family of sensors and data aquisition units attest to a vast history of experience in designing vehicle test equipments.
Pegasem offers driver displays (P100 series) that can scale a digital/pulse value as well as an analog input, plus compact and powerful in vehicle test displays and measurement systems. These units work great with existing transducers – mechanical, optical or GPS. They also manufacture conventional 5th wheels, wheel speed encoders/sensors, microwave ground speed sensors, pedal force transducers, string pots, wheel hub telemetry, modular wheel hub/body mounting systems (lug nut, collet, and magnetic cap) and sliprings.
5th-Wheel for Vehicle Testing
5th-wheels of PEGASEM stand out because of their precision, compactness and carefree reversing ability. The integrated sensor delivers stable measurement data even on critical surfaces e.g. on flooded test tracks where non-contact speed sensors often fail.
Ground Speed SensorsPEGASEM Radar Sensors allow carefree non-contact speed sensing over ground. The road surface is scanned with a 24 GHz radar beam. The internal processor creates a high precision TTL- output signal with 100 pulses per metre from the raw Doppler signals.
Pedal Force Sensor
Offers a very low radar cross section used for testing AEB VRU scenarios. Extremely low profile and is very robust, can be driven over by passenger and commercial vehicles. Speeds up to 50 km/h (72km/h)
Wheel Speed Sensors PEGASEM Wheel Speed Sensors offer high precision information as to the rotational speed of the car wheels, they can also be used as precise vehicle speed and distance transducers.
Slipring System for Car Wheels
For measurements at rotating parts located at the car axle the PEGASEM Modular Mounting System (MMS) is available with a 8 channel slip ring assembly in a waterproof package.
Wire Displacement Sensors
The PEGASEM MMS Mounting System is now available in combination with a wire displacement sensor. This sensor can be fitted to a vehicle‘s wheel hub and fender within a few minutes.
PEGASEM P100 Series
The P100 driver displays are used as as control monitor for the vehicle speed and as a node for the sensor wiring during vehicle tests. Furthermore the P110 and P120 units allow simple tests on vehicles like stopping distance, turning circle or round trip time.
