摘要
由于碱金属的熔点较高,并且金属活动性较强,常见的压力传感器无法进行测量。设计了一种用于液态碱金属压力测量的差动变压器式差压传感器,介绍了传感器的工作原理和具体设计方案,可以根据需要输出标准电流信号4~20 m A或数字通讯RS485,并可通过LAN接口实现远程监控和数据优化等功能。
The alkali metal can hardly be measured by common pressure sensor because of its higher melting point and strong metal activity. This paper designs a differential transformer type of differential pressure sensor for measuring liquid alkali metal pressure, introduces the working principle and specific design plan of the sensor, The sensor can output standard current signal of 4-20 m A or digital communication of RS485 according to the needs, and realize the functions of remote monitoring and data optimization through the LAN interface.
