Capacitance Level Transmitter

Published on : Tuesday 30-11--0001

Capacitance Level Transmitter is used in sensing level of liquids. Capacitance Level Transmitter can be used for conductive as well as nonconductive liquids. It is offered with PTFE sleeve for better insulation & to withstand high temperature in conductive tanks the insulated probe acts as one electrode & the tank wall as another electrode, any change in liquid level the dielectric value will change thereby changing the capacitance value proportional to the liquid level. In case of nonconductive tanks, a reference probe is provided as ground electrode. 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.
