  • Media isolated differential pressure sensor and fluid injection method
    Patent number: 5741975
    Abstract: A pressure sensor (10) includes a base (12) supporting a lead frame (28) having a pressure sensing element (14) electrically coupled to the lead frame (28). The molded base (12) interlocks with first and second diaphragm mounting frames (18, 20) and together with first and second diaphragms (22, 24) forms first and second chambers (36, 40). An incompressible fluid resides in the first and second chambers (36, 40) and transfers the pressure of a sensed media impinging on either of the first or second diaphragms (22, 24) to the pressure sensing element (14). The incompressible fluid filling the first and second chambers (36, 40), together with the flexible and impermeable membrane material of the first and second diaphragms (22, 24) effectively isolates the pressure sensing element (14) from the sensed media.
