Capacitive Level Sensor


Capacitive Level Sensor

Process Control Devices offers Capacitive Level Sensor. Process Control Devices offers a series of liquids level transmitters designed for immersion in open Tanks, Wells, Groundwater and Reservoirs tanks. The capacitive level sensor, Switch, and Transmitter is suitable for level measurement and control of liquids, chemicals, and some slurry. The tank wall and sensor probe form the two electrodes of a capacitor. When the level varies, the electrical capacitance between the electrodes also changes. This change is calculated by the electronics system and converted into an output signal. The performance of these instruments is not affected by the physical properties of the liquid such as density, conductivity, corrosive nature and viscosity.
