Reliable level alarm and control of liquids and solids

As a liquid or solid rises or lowers around the probe, the capacitance field changes. This is monitored and used to control the two onboard relays.

Each relay includes full differential control to allow the relay to activate and de-activate between two distinct at user determined points on the probe. This can be used for pump and valve control between high and low level points. Adjustable time delay is standard to suppress spurious alarms from turbulence.
