working principle:
Based on the ceramic capacitor technology, when the liquid level increases, the pressure applied to the ceramic capacitor increases, so that the capacitance value increases, and the capacitance value is proportional to the liquid level.
Features:
Input-type installation, strong overload capability, good stability, better than 0.1% of full scale every year, strong anti-interference ability, high precision and repeatability, up to 0.2, 0.5 level, can adjust zero point and full scale in the field. The ceramic measuring interface has good corrosion resistance.
