Design and Research of Pneumatic Sensor for Nuclear Fuel Reprocessing Equipment

In the radiation environment, the traditional electronic trigger sensor will receive the interference of radiation, resulting in inaccurate signal transmission, easy to generate wrong signals and cause misoperation, there are security risks. Therefore, this paper studies a kind of pneumatic sensor used to detect the position trigger of the silo, and has the function of rapid disassembly and assembly. In the radiation environment, the robot can be used to quickly disassemble and retrieve the sensor, so as to facilitate the maintenance and repair of the sensor. The simulation design of mechanical structure, trigger device and air path system in pneumatic sensor is emphasized. In the radioactive source environment, air pressure signal is used instead of electrical signal to detect the equipment in place, which ensures the signal safety of the equipment.
