ABSTRACT:
A pressure sensor for sensing a pressure level of a pressurized medium. The pressure sensor includes a housing that has a high pressure side, a low pressure side and an aperture. A substrate is located in the aperture. The substrate has a pair of ends and a center portion. The center portion is brazed to the housing in the aperture. The center portion seals the high pressure side from the low pressure side. A pressure sensitive resistor is mounted to one end of the substrate. A reference resistor is mounted to another end of the substrate. A circuit line is located on the substrate. The circuit line is connected between the pressure sensitive resistor and the reference resistor.
