摘要：In an acceleration sensor, in particular for automobiles, at least two electrodeswhich are surrounded by a dielectric are arranged, substantially parallel to each other, ina housing and immersed over part of their length in an electrically conductive liquid. Flip-flops output pulses having durations based on capacitance of the sensor. Output signalsof the flip-flops are combined arithmetically.
