Gladiator Conductivity Level Switch

Gladiator Conductivity Level Switch

The Gladiator Smart Conductivity Switch is a third-generation, state-of-the-art level probe, designed to operate in tough industrial environments. The probe of the Conductivity Switch forms one part of an electric circuit, with the vessel wall or a reference probe making another part. A conductive liquid between the probe and the vessel wall (or between the probe and the reference probe) links the two parts of the circuit and the output will switch in response. The output has adjustable hysteresis and delays for on or off switching. A test function is available to remotely confirm the probe integrity by switching the relay contacts. The Gladiator Smart Switch Series includes communications capability for remote adjustment, control and monitoring.

Principle of Operation

A low voltage AC signal is applied between the probe electrode and the tank wall or reference electrode in the case of a non-metallic tank. When the liquid comes into contact with the electrode tip, a conductive path is established between the sense electrode and the metallic tank wall/reference electrode. Current flow due to the conductive path is sensed, amplified and used to switch a relay for indication or control purposes.
