660 Series Multi-Point RF Level Switch

The 660 Series provides the options of multiple point switching plus narrow and wide differential switching. 

By combining these features, the 660 Series units can be used for a wide variety of control needs.

The available switching combinations are designed to provide multiple alarms, pump/valve control, or a combination of alarms and equipment control. 

The 660 Series makes it possible to combine up to four single point devices into one package for reduced maintenance. 

Switching Combinations: The 660 Series has eight different combinations of fixed differential and/or adjustable differential switching points. 

Each unit is equipped with one of four discreet switching points. These points can be used to provide true point level sensing with no level differential, or latched together to provide wide, adjustable differential.
