Capacitance Level Transmitter – Description

A Capacitance Level Transmitter is a continuous level measurement device that operates on the principle of capacitance change between a probe and the tank wall (or reference electrode). As the level of liquid, slurry, powder, or granular material changes, the capacitance value varies proportionally. The transmitter converts this change into a standard 4-20 mA output signal for monitoring and control purposes.

Capacitance Level Transmitters are widely used for measuring levels in storage tanks, process vessels, silos, and hoppers. They are suitable for a variety of media including liquids, conductive and non-conductive fluids, chemicals, oils, powders, and bulk solids. The instrument provides reliable and accurate level measurement even under challenging process conditions such as high temperature, high pressure, and corrosive environments.
