Hawk Measurement Gladiator Conductivity Switch

Principle of Operation:

Hawk Measurement Gladiator Conductivity Switch uses 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.
