Features ■ Non-contacting sensor ■ Operating temperature: -40 °C to +85 °C Commercial Vehicle Non-Contacting Chassis Level Sensor - Type R11700 General Function Bourns® Type R11700 Non-contacting Chassis Level Sensor is used to measure the vehicle height in commercial vehicles or busses. The sensor sends a continuous signal which is an indicator for the level of the chassis. It is mounted at the frame of the commercial vehicle or bus. The sensor measurement is non-contacting and is based on magnetic field direction measurement. An outside lever is mounted at an axle and turns a magnet inside the sensor housing. The output signal of the sensor is proportional to the angle of the sensor axle. General Specifications Ambient Conditions ............................................
