Abstract
A capacitive sensor is compensated for changes in the ratio of the capacitances of a pair of capacitors which result from changes in a relatively static background condition such as pressure. The compensation is achieved by providing a shunt capacitance for one of the sensor capacitors, the shunt capacitance being located such that it will not be effected by the background condition.
