Pressure and temperature sensor |
摘要 |
A hybrid sensor for simultaneously sensing pressure and temperature in non-interacting manner, includes an insulative substrate having a temperature-sensitive printed thick film resistor fabricated thereon. A conductive plate is insulatively spaced above the resistor and supported by a pressure-tight insulative barrier. The distributed capacitance between the plate and the resistive pattern is a function of the pressure applied to the exterior face of the plate, while the resistance of the resistive thick film is a function of temperature of the surrounding environment.
