Abstract: A capacitance type pressure transducer which avoids errors due to changes in temperature has a pressure responsive capacitor and a fixed reference capacitor connected in a circuit to provide an output proportional to the ratio of the capacitances as a function of pressure. Since both capacitors are subjected to the same temperature changes any variations in capacitance due to temperature is cancelled out in the ratio.
