Conductivity Level Switch Working Principle

Conductivity Level Switch

The Conductivity Level Switch of a liquid medium might range extensively. As soon as the liquid reaches the fill prohibit decided from the setup top of the electrode, the liquid medium closes the DC unfastened alternating present circuit between the 2 electrodes (or between the container wall and an electrode). A switching sign is made from the unexpected building up in the present intake.

Acids, yes and answers containing water are conductive and are detected rather well. Competitive liquids will also be detected with out issues the usage of probes constituted of highly-resistant fabrics. Flammable liquids comparable to fuels, oils, and solvents are nonconductive and can’t be measured via this size theory.


Operation Mode

Two electrodes are put in above the skin of the conductive liquid to be monitored. If the liquid degree rises to the purpose the place each electrode is involved with the liquid, the present circuit of an attached relay is finished by the use of the 2 electrodes and the liquid, activating a switching sign.

The minimal Conductivity Level Switch of the liquid should be 10 µS/cm. Those prerequisites are fulfilled via almost all conductive liquids, comparable to water, acids, and yes, except for natural solvents.

If a number of switching issues are wanted, a couple of electrodes must be used. To be able to keep away from electric results within the liquid, a DC unfastened alternating present is used for size. That is generated via an electrode relay or a converter.

Interfacial degree detection will also be simply and economically completed with this size approach. Specifically, with oil and petrol separators, the prohibit price between the water and the nonconductive liquid is simple to discover.


  • Easy, cost-effective measuring theory
  • Multi-point detection with one procedure connection
  • Liquid meals programs


  • To keep away from overflow
  • For keeping up a continuing degree to keep away from subject matter wastage
  • For switching off pumps when operating dry and indicating an empty tank to keep away from  putting on and tear and manufacturing stoppage
