Abstract
A transducer for sensing pressure has a first and a second pressure chamber for sensing pressure and a center stop which has two substantially flat faces, each face cooperating with an associated sensor diaphragm which forms the first and the second pressure chamber. The two chambers are fluidically coupled together. Each of the diaphragms is responsive to a pressure P1 or P2 respectively and the transducer is easily configured to sense differential, gage or absolute pressure. When the pressure to be sensed exceeds a predetermined value the affected sensing diaphragm is supported by the respective substantial flat face of the center stop.
