Conductive Level Electrical Switch

PROTOCONTROL make conductive Conductive Level Electrical Switch from Pune, Maharashtra, India that is used to sense the level of water, acid, Salt various chemicals, sugar solutions, milk, juice, sewage, drinks, wet pulp, ammonia etc. Conducive type level switch automatically controls liquid levels in any container. This is low current operated circuit ensures personnel safety.

These are simple & low cost level controller working on the conductivity principle suitable for liquid with conductivity higher than 20 microsec/cm. Probes are immersed into the tank, for detecting the level. These probes serve as contacts of an electric circuit.
Conductive level switch can be equipped with maximum 4 probes & an additional reference probe for cases of non conductive signal. Their length should be in accordance with the level to be detected.

When a conductive fluid comes in contact with two or more of the sensing electrode , an electric circuit gets completed. A very small alternating voltage is applied between two probes & vessels wall. The circuit gets closed by liquid when liquid touches the probe tip. The voltage & current used are so small that no dangerous shock hazard can occur. The use of alternating voltage prevents deposition & electrolysis.
