Differential oil-filled pressure transducers with compensating capsule

A compensated oil-filled differential pressure transducer assembly, comprising:

• a main input port configured to receive a main pressure;
• a reference input port configured to receive a reference pressure;
• an oil-filled main pressure sensing capsule configured to output a main pressure signal responsive to the main pressure received at the main input port and a first common error signal responsive to a common stimulus acting on the oil-filled main pressure sensing capsule, the oil-filled main pressure sensing capsule comprising a main pressure sensing element in communication with the main input port;
• and
• an oil-filled reference pressure sensing capsule mounted in a same orientation as the oil-filled main pressure sensing capsule, the oil-filled reference pressure sensing capsule configured to output a reference pressure signal responsive to the reference pressure received at the reference input port and a second common error signal responsive to the common stimulus acting on the oil-filled reference pressure sensing capsule, the oil-filled reference pressure sensing capsule comprising a reference pressure sensing element in communication with the reference input port.
