Model 107

SKU: 107

Capacitance Level Switch, Multipoint, Two or Four DPDT Relays

The Delta Controls Model 107 Multi-point Capacitance Switch uses RF admittance technology to produce switching action when a material level crosses the switchpoint. The interface position between two liquids with different dielectric constants is accurately detected, including with cloudy interface conditions. One of the liquids should be nonconductive. Model 107 is not sensitive to specific gravity (SPG) variations.

Many probe configurations are available. The electronics module can be remotely mounted.

107 features digital circuitry, pushbutton setup, LCD display, and is potted for severe environments. Simple, two point calibration allows calibration and recalibration to occur without emptying tank. On/off elevation is separately selectable for each of the two 5 A DPDT relays.
