摘要
研制了一种采用磁性浮子和干簧管为传感器的液氮液面监视系统。传感器灵敏可靠,工作时几乎不消耗能量,引线对液氮产生的附加漏热小,可以长期监视液面。
A new monitor of liquid nitrogen level have been developed.The sensor using magnetic foam and dryreed switch is very reliable and almost without energy consumption when it works.It can be used to monitor liquid nitrogen level continuously.
