低温储罐电容液位计设计

低温液化气体的相对介电系数都很小 ,电容液位计传感器的电容变化量很小 ,传感器的灵敏度比较低 ,针对这一问题 ,对液位计设计进行分析 ,提出解决方案。低温液体的温度不是一直不变的 ,气体和液体的相对介电系数都将改变 ,需要进行修正。文中提出一种新的电容液位测量方法

The Design of Capacitive Level Gauge Used in Cryogenic Tank

Because of the low relative dielectric constant of cryogenic liquefied gas, the capacitive diversification of the level gauge is little. In the case, some analyses are presented. In the light of various relative dielectric constants due to the change of the temperature, the results of the system must be revised. To solve the this problem, a new measure is given.
