Abstract

The invention discloses a gasket structure passive wireless temperature sensor. The temperature sensor includes a surface acoustic wave sensor chip, a sensor antenna, a circuit board and a sensor support seat; the temperature sensor is in a gasket structure; the sensor antenna and the circuit board are annular structures having circular through holes; the sensor support seat is provided with a cylindrical boss structure matching the circular through holes; the cylindrical boss structure of the sensor support seat is successively inserted into the circular through holes of the sensor antenna and circuit board; the sensor antenna and the circuit board are fixedly connected to the sensor support seat; and the surface acoustic wave sensor chip and the sensor antenna are connected to the circuit board. The installation and fixing of the sensor can be conveniently realized by the annular structures, and the wireless transmission stability can be guaranteed by the annular antenna; the temperature sensor is small in size, light in weight and stable in structure, and can work in harsh environments such as strong magnetic fields, high temperatures and strong radiation; and the temperature sensor is suitable for the temperature monitoring of electrical equipment such as switchgears, transformers and high voltage cables.

Description

technical field [0001] The invention belongs to the technical field of temperature sensors, and relates to a gasket-structured passive wireless temperature sensor, in particular to a gasket-structured temperature sensor based on passive wireless surface acoustic wave technology. Background technique [0002] During the use of the switch cabinet, it is necessary to detect the temperature of the electrical components in the cabinet to avoid safety accidents caused by excessive temperature. Traditional temperature measurement systems such as infrared, optical fiber, and active wireless have certain technical defects in terms of safety, stability, and real-time performance. The failure rate is high and cannot fully meet the requirements of use. Therefore, passive wireless temperature sensors based on surface acoustic wave technology are more and more widely used in electrical equipment such as switch cabinets. At present, the passive wireless temperature sensors commonly used i...
