Abstract
A circuit for linearizing the output of a differential pressure transducer includes first and second operational amplifiers. Each amplifier is associated with threshold devices as diodes so that one amplifier will be active for one condition of output polarity while the other amplifier will be active for the other condition of output polarity. The output of the amplifiers are connected to a common terminal which provides a compensating biasing voltage to the transducer. The voltage varies in a 'V' shaped characteristic to enable one to achieve a linear output voltage from the transducer for both positive and negative pressure differences.
