Capacitance Level Transmitter

What is Capacitance Level Transmitter?

Capacitance Level Transmitter is the type of transmitter that operates like a capacitor. These capacitors consist of two conductive plates which are separated by the medium called as insulating material having dielectric constant. The insulated electrode acts as the first plate and the other plate comprises a tank wall or reference electrode.

Working Principle Their working depends upon the principle of change of capacitance. The capacitance depends upon the variety of fluid level such as aqueous and organic liquids, solids, slurries, powders, granular material, etc.

The output is 4-20mA, 4 wire connections for isolated supply & 3 wires for non isolated supply. 2 wire loop powered output is also available. The tank empty (4mA) & Full (20mA) calibration is through easy field calibration button in case of 4 wire & 3 wire. For 2 wires it is through multi turn trimpot. Rigid probe is offered for tank depth upto 3 mtr & Flexible probe upto 15mtr. Capacitance Level Transmitter is available with different mounting arrangement to suit customer requirement. It is widely used for water, diesel, oil and chemical application.
