Design of The SiCN Temperature Sensor Detecting System Based on LabVIEW

摘要

The SiCN temperature sensor is a passive wireless sensor cavity, which uses SiCN ceramic as dielectric resonator, the material has some advantages such as thermal shock, corrosion and oxidation resistance, etc. Through the analysis of resonator sensor modeling, uses the theory of weak-disturbance modifying measuring, and uses the NI Company of the PXIe-5644R vector signal transceiver (VST), circulator, waveguide and high-frequency devices, the paper designs a SiCN temperature sensor detection system based on LabVIEW. The PC displays processing analysis and storages the sensor signal, so as to measure the characteristics of the sensor. The system can detect a variety of models of the sensor, and has a strong ability to upgrade and expand.
