Product Overview

CWASeries RFCapacitive object/The liquid level switch has a simple structure, no mechanical transmission structure, so it will not cause mechanical wear, long service life, easy installation, and simple debugging.

CWAThe series of products have undergone a brand new circuit design, upgrading analog circuits to digital intelligent circuits, greatly improving users' practical operational efficiency, enhancing product stability, and greatly improving accuracy to easily cope with different material characteristics.

CWASeries products are suitable for most solids/Liquid measurement (including viscous materials) can set appropriate alarm points with just one click calibration. It can be equipped with an operator to detect measurement values in real time and modify alarm values, hysteresis values, delay values, and high/low alarm switching; In addition, the intelligent LCD model can display real-time detection values and set alarm output values, delay values, hysteresis values, and high/low alarm switching to meet different user needs.

working principle

CWASeries RFCapacitive object/The liquid level switch uses the capacitance formed between the sensing electrode and the grounding electrode, with the measured material as the medium. When the material covers the sensing electrode

When using electrodes, the measured capacitance value will increase and output a switch signal when it reaches the set value.
