摘要
为了解决传统表压式液位传感器长期存在的结露问题 ,提出了采用绝对压力传感器 ,利用虚拟参考压力点技术 ,消除结露对液位传感器稳定性的影响 。
To solve the long-standing dewing problem in conventional manometer pressure sensors,a new method is proposed by using absolute pressure sensors.It utilizes the virtual reference pressure spot techniques to eliminate the dew's influence on the stability of liquid level sensors.An effective approach is also proposed to prevent lighting stroke for outdoor using sensors.
