摘要： A combined pneumatic and hydraulic pressure transducer is comprised of a pressure capsule with an open interior divided into first and second sections by a partition wall, and a respective axially displaceable diaphragm extends across each of the sections defining third and fourth pressure chambers which change in volume due to axial displacement of the respective diaphragms. A rigid piston intermediate member extends through the partition wall and joins the diaphragms to move together. Connections communicating between the third pressure chambers and between the fourth pressure chambers pass through the intermediate member. A respective hydraulic cylinder at each end of the pressure capsule receives and operates upon a respective end of the intermediate member.
