Integrated pressure and temperature sensor

摘要

A temperature and pressure sensor for sensing the temperature and pressure of a media and providing electrical signals that are indicative of the temperature and pressure level of the media. The 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 affixed to the housing. The center portion seals the high pressure side from the low pressure side. A pressure sensitive resistor and a thermistor are mounted on one end of the substrate and a reference resistor is mounted on the other end of the substrate.
