Capacitive level sensor is transmitter that use a coaxial container. The capacitor is composed of two coaxial cylindrical plates, an inner electrode and an outer electrode. When the liquid enters the container, the capacitance value between the sensor shell and the sensing electrode will change, and the standard current, voltage or digital signal will be output. It is suitable for measurement of conductive liquids.
Tips: What is a capacitance level sensor?
The principle of capacitive level sensor is to use the capacitance formed by filling the liquid medium between the positive and negative probes to change linearly with the liquid level, and convert the change of capacitance (the change of liquid level) into a standard electrical signal output. The core component of the product adopts a highly integrated dedicated capacitance measurement chip, which has the advantages of high precision, high stability and continuous measurement after accurate temperature compensation and linear correction.
