ABSTRACT:
A pressure sensor for sensing a pressure level of a pressurized medium. In one embodiment, the pressure sensor has a high pressure side and a low pressure side. An aperture may extend through at least a portion of the sensor assembly, and a seal is located in the aperture. The seal seals the high pressure side from the low pressure side. Electrical leads extend through the seal between the high pressure side and the low pressure side. A substrate is located on the high pressure side. A pressure sensitive resistor is mounted on the substrate such that the resistor is directly exposed to the pressurized medium. The resistor changes resistance in response to a change in pressure. The resistor is connected to the electrical leads.
