摘要（英）：

The utility model discloses a passive wireless temperature sensor with a gasket structure. The passive wireless temperature sensor comprises a surface acoustic wave sensor chip, a sensor antenna, a circuit board and a sensor support, the temperature sensor is of a gasket type structure; the sensor antenna and the circuit board are both of an annular structure with a circular through hole. The sensor support is provided with a cylindrical boss structure matched with the circular through hole; the cylindrical boss structure of the sensor support is sequentially inserted into the sensor antenna and the circular through hole of the circuit board, and the sensor antenna and the circuit board are fixedly connected with the sensor support; and the surface acoustic wave sensor chip and the sensorantenna are connected with the circuit board. The annular structure enables the sensor to be easy to install and fix, and the annular antenna also guarantees the stability of wireless transmission. The utility model has the advantages of small volume, light weight and stable structure, and can work in severe environments such as strong magnetic field, high temperature, strong radiation and the like. The temperature monitoring device is suitable for temperature monitoring of electrical equipment such as switch cabinets, transformers and high-voltage cables.
