Product overview
Sigma conductivity level switches are simple, low cost and reliable instruments for detecting conductive liquids, available for single point or multipoint level detection.
How it works
A low alternating voltage is applied between the active electrode and the vessel wall or a reference electrode. When the liquid touches the tip of an electrode it completes the circuit to ground and a current flows. In integral and multiwire designs this signal goes straight to the control unit, while two wire designs use a pre amplifier in the probe head. The control unit amplifies the signal to drive LED indication and relays.
