Piezoresistive ceramic temperature and pressure sensor strain gauge and preparation method thereof
The invention discloses a piezoresistive ceramic temperature and pressure sensor strain gauge and a preparation method thereof, the piezoresistive ceramic temperature and pressure sensor strain gauge is applied to the field of sensitive elements and sensors, and the technical scheme is characterized in that a Wheatstone bridge is formed between piezoresistors R1-R4 and zero-setting resistors R5-R6, when no pressure is loaded, the Wheatstone bridge is balanced, and when no pressure is loaded, the zero-setting resistors R5-R6 form zero-setting resistors R5-R6; the Wheatstone bridge is provided with a power supply input terminal V +, a GND terminal, a positive voltage signal output terminal S + and a negative voltage signal output terminal S-, voltage is loaded between the power supply input terminal V + and the GND terminal during use, a temperature resistance output terminal T is arranged on the GND terminal, and a temperature sensitive resistor R7 is connected between the temperature resistance output terminal T and the Wheatstone bridge; the ceramic temperature and pressure sensor has the technical effects that the problems that a conventional piezoresistive ceramic pressure sensor cannot acquire temperature, is long in calibration time and has a thermal hysteresis effect are solved, the structure of the ceramic temperature and pressure sensor is simplified, and the problems that an additional leakage-proof design is needed and an NTC resistor pin is prevented from being disconnected are avoided.
