ABSTRACT:
A sensor for a height control system uses a transducer to detect changes in position of an arm relative to a vehicle and sends a proportional signal to a microprocessor that, in turn, actuates a pneumatic valve operably connected to an air spring between the arm and the vehicle. The transducer includes an optical bridge, a variable capacitor, or a flexible variable resistor.
