ABSTRACT:
There is disclosed a transducer to sense the vacuum in the intake manifold of an engine or other chamber. The electrical signal it produces is converted into digital signals for operating a liquid crystal display. The output of the transducer is also coupled to a driver which is operable in one mode to produce energizing currents on all of its outputs corresponding to the amplitude of the electrical signal. The driver is coupled to LEDs which are thus illuminated. The driver is also operated in a second mode so that only one of the outputs is energized and in that mode the driver receives only the AC component of the transducer output.
