Model 107 • Capacitance Level Switch, Multi-point, Two or Four DPDT Relays Features RF admittance type circuitry Insensitive to process coatings and buildup LCD direct reading level display Digital pushbutton setup and calibration Simple, two point calibration without emptying tank Direct or reverse calibrated Built-in self-diagnostics Integral or remote mounted electronics housing Process temperature -350 °F to +750 °F (-210 °C to 435 °C) High or low relay fail-safe action Adjustable time delay of 1 to 60 seconds Epoxy sealed electronics module Pressure Rating: Vacuum to 10 000 psig (-1 bar to +700 bar) Application specific probe shapes, styles, configurations, and process connections Wetted materials include stainless steel, PTFE, Kynar® , Monel, and ceramic Description 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.
