摘要:
A pressure sensor connector (10) for use with a pressure sensor element (12) that includes a plurality of pressure sensor terminals (13). The pressure sensor connector (10) includes a housing (18), a plurality of connector terminals (20) and a flexible circuit (22). A plurality of electrical pathways (24), formed on the flexible circuit (22), connect each of the plurality of connector terminals (20) to a corresponding pressure sensor terminal (13).
摘要:
A method of making a low-cost metal diaphragm sensor that integrates both pressure and temperature sensing in a single sensor assembly utilizes thick-film processing to form a circuit including stress and temperature sensitive elements on the outboard or exposed surface of a thin metal diaphragm separating the circuit from a pressurized fluid. Only a thin layer of dielectric separates the stress and temperature sensitive elements from the diaphragm surface. The stress sensitive elements respond to mechanical stressing of the diaphragm due to the presence of the pressurized fluid, while the temperature sensitive element responds to the temperature of the pressurized fluid. The thermal capacity of the fluid greatly exceeds that of the diaphragm, so that the temperature responsive characteristic of the temperature sensitive element accurately reflects the temperature of the pressurized fluid.
