Model 107 Capacitance Level Switch
Brand: Delta Controls CorporationCapacitance Level Switch, Multipoint, Two or Four DPDT Relays.
The Delta Controls Model 107 features all digital circuitry and pushbutton setup. It is potted for severe environments.
An LCD display reads level directly in gallons, inches, meters, tons, etc.
Pushbutton setup and simple two point calibration means you don’t have to fill or empty the tank to calibrate or recalibrate switching points accurately.
The “ON”-“OFF” elevation is separately software selectable for each relay.
The Model 107C provides two 5 Amp DPDT relays. The Model 107D provides four DPDT relays.
The electronics module can be remotely mounted.
