Design and Research of a Pneumatic Sensor Suitable for Radioactive Environment

在放射性环境中,传统电子元器件式传感器会受到辐射的干扰,导致信号传输不准确,容易产生错误信号并造成误操作,存在安全隐患。研究了一种用于检测放射性环境下推送机构运动到位的气动传感器,该传感器具有快速拆装的功能。在放射性环境下,通过专用电动工具可以快速拆卸和取回传感器,方便传感器的维护和维修。对气动传感器的机械结构、触发装置和气路系统进行了仿真设计。在放射性环境中,使用气压信号代替电信号检测设备运动到位,保证了设备的信号安全。

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 mis-operation,there are security risks.Therefore,this paper studies a kind of pneumatic sensor used to detect the position trigger of a push mechanism in the radioactive environment,and has the function of rapid disassembly and assembly.In the radiation environment,the special electric tools 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.
