    • A resistive strain gauge pressure sensor including upper and lower housings coacting to define a pressure chamber within the housing (12, 14). A board member (20) is clamped between the housings and defines a diaphragm portion (20h) which extends across the pressure chamber to divide the pressure chamber into upper and lower chamber portions. All of the circuitry of the sensor is screen printed onto the lower planar face (20b) of the board member including the various resistor elements of the strain gauge assembly (34), the various elements of the conditioning circuit (36) receiving the output of the strain gauge assembly (34), and the various further leads required to connect the circuitry elements to the terminals of the sensor. The sensor terminals are provided by a plurality of connector pins (23) extending downwardly through the board member for connection at their respective lower ends (23b, 23c, 23d) to the circuitry provided on the lower face of the board member.
    • 一种电阻式应变计压力传感器,包括上部和下部壳体,共同作用以在壳体(12,14)内限定一个压力室。 板构件(20)夹在壳体之间并且限定了延伸穿过压力室的隔膜部分(20h),以将压力室分成上部和下部腔室部分。 传感器的所有电路被丝网印刷到包括应变仪组件(34)的各种电阻元件的板构件的下平面面(20b)上,调理电路(36)的各种元件接收 应变计组件(34)以及将电路元件连接到传感器的端子所需的各种其它导线。 传感器端子由多个连接器销(23)提供,该多个连接器针脚(23)向下延伸穿过该板构件,用于在它们各自的下端(23b,23c,23d)处连接到设置在该板构件的下表面上的电路。
