Design of Signal Transceiver System Based on High Temperature Sensor SiCN

Abstract

Abstract-This paper puts forward the passive and wireless SiCN temperature sensor in the applicability and necessity of the turbine engine internal environment temperature measurement. Using the principle of resonance frequency scanning tracking method based on perturbation to be the system test method, while the sensor feedback signal and the input signal ratio (S 11 ) parameter as data analysis, and establish the relationship between the resonance frequency and temperature by means of tests. Experimental results show that with increasing temperature from 25 to 300 , the SiCN sensor resonance frequency ℃ ℃ decreases. Corresponds to the theoretical derivation, and the minimum frequency temperature gradient is 45.92kHz/ . ℃ Therefore, under certain conditions, the hardware system can replace the network analyzer to work at the temperature test of SiCN sensor.
