ABSTRACT:
A pressure transducer system for developing accurate pressure measurements with a torque driven pressure transducer where the transducer has dual capacitor devices in tandem and mechanically coupled to permit relative displacement along a elongated axis in response to temperature and where the devices are displacable by angular torque about the elongated axis to obtain independent correlatable measurements from the dual capacitor devices.
