Abstract
An airspring height control device is based on an infrared light emitting diode and photo transistor receiver combination to reflect a signal from a reflector located internally to an airspring. The variable output signal given off by the receiver is proportional to the distance from the transmitter/receiver to the reflector thus allowing a height controlling mechanism to respond to the signal and make the necessary adjustments.
