传统电容式物位传感器在测量导电介质时,无法消除电极挂料对测量的影响,本文通过分析电极挂料的等效电路,提出了带有电极挂料的物位计测量电路,并指出在一定的初始条件和测量条件下,测量电路的输出电压仅与物位电容有关,而与电极挂料无关,这为今后进一步研制开发新型电容式物位计,消除电极挂料的影响提供了理论依据 The traditional capacitive level sensor can not eliminate the influence of the electrode hanging material on the measurement when measuring the conductive medium. In this paper, by analyzing the equivalent circuit of the electrode hanging material, a level measuring circuit with electrode hanging material is proposed, Under certain initial conditions and measuring conditions, the output voltage of the measuring circuit is only related to the capacitance of the level, and has nothing to do with the electrode dangling, which provides a theory for further research and development of the new capacitive level gauge in the future to eliminate the influence of electrode dangling in accordance with
