Abstract:
A solid state gas pressure sensor has a resistor of polysilicon deposited upon a dielectric substrate which electrically isolates and thermally prevents heat transfer to other devices thereon. A constant voltage is applied to the resistor. Depending upon the gas pressure over the sensor, a given current will be output once temperature equilibrium is established. A change in the gas pressure changes the output current of the resistor. The output current indicative of pressure is temperature corrected. Patents. MJM
