Capacitance Level Transmitter

Capacitance Level Transmitter is a compact, low cost, level transmitter with 4-20 mA analogue out-put designed to measure the level of various liquids, and solid in tanks or storage vessels. Mea-suring range is 0.25 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 ca-pacitances exists between the electrode And the metal well or the aux-iliary reference probe.

When the probe become covered with material to be measured the capaci-tances will increase and the change will be measured and covered into an analogue (4-20 mil) 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 based etc only insulated probe are suggested

Non Conductivity Material:

• Mostly petrochemical and solvents insulated or non insulated probes can be used
