Capacitance Level Transmitter


Levsen series CLT-90 Capacitance Level Transmitter is a compact, low cost, Loop Power level transmitter with 4-20
mAanalogue out-put designed to measure the level Of various liquids, and solid in tanks or storage vessels. Measuring range is 0.2 to 3 m for rod probe version. The probe forms an electrical capacitor with the surrounding metal contained wall, or with auxiliary reference probe. With the vessel empty, an initial capacitances exists between the electrode And the metal well or the auxiliary reference probe. When the probe become covered with material to be measured the capacitances will increase and the change will be measured and covered into an analogue (4-20 mA) output signal proportional to the change. Rod or flexible cable can be used for various conductive or non conductive Liquids.

Conductive material: Water based solutions. Acids, Bases etc – only insulated probe are suggested.
Non-Conductive material: Mostly petrochemical and solvents – Insulated or non insulated probes can be used.
