摘要： There is disclosed a high temperature pressure sensing system which includes a SOI, silicon carbide, or gallium nitride Wheatstone bridge including piezoresistors. The bridge provides an output which is applied to an analog to digital converter also fabricated using SOI, silicon carbide, or gallium nitride materials. The output of the analog to digital converter is applied to microprocessor, which microprocessor processes the data or output of the bridge to produce a digital output indicative of bridge value. The microprocessor also receives an output from another analog to digital converter indicative of the temperature of the bridge as monitored by a span resistor coupled to the bridge. The microprocessor has a separate memory coupled thereto which is also fabricated from SOI, silicon carbide, or gallium nitride materials and which memory stores various data indicative of the microprocessor also enabling the microprocessor test and system test to be performed.

摘要： The present invention provides a self-heated pressure sensor assembly and method of utilizing the same. The self-heated pressure sensor assembly regulates and maintains the temperature of the pressure sensor, regardless of the external temperature environment, without an external heater as in prior art embodiments. Exemplary embodiments of the pressure sensor assembly incorporate a resistance heater that is built into the sensing chip of the pressure sensor assembly. The pressure sensor assembly also utilizes the resistance of the pressure sensing elements to monitor the temperature of the assembly, which works alongside the resistance heater to maintain a stable temperature within the pressure sensor assembly.
