Conductivity Type Level Detector Switch Review

Within the Illustration below, is a conductivity probe level detection system. It consists of one or more level detectors, an operating relay, and a controller. When the liquid makes contact with any of the electrodes, an electric current will flow between the electrode and ground. The current energizes a relay which causes the relay contacts to open or close depending on the state of the process involved. The relay in turn will actuate an alarm, a pump, a control valve, or all three. Atypical system has three probes: a low level probe, a high level probe, and a high level alarm probe.


Conductance based level switches can be adapted to work with variety of applications. Following are the major applications of these liquid level switches:

  • Applied for both high/low level alarm indication as well as pump valve control.
  • Employed in cases of run-dry protection and tanks overfill also.
