The AT 120 is a float level switch designed for intensive pump control where clear liquids, clean liquids, rain water, certain types of wastewater are used. This feature is highly appreciated in very agitated and turbulent liquids.
It is highly recommended to use external ballasts and cable hangers with our float level switches.
The AT 120 float switch is available in 3 versions: (1) Emptying / Filling (2) Emptying + ground wire (3) "Special" emptying mode with multifunction plug for the automation of manual pumps.
This model is available with a HR HY (High Resistance) press-vulcanised housing for applications in aggressive liquids (acids, solvents, hydrocarbons, etc.) See AT 120 HR HY.
For pump control of several levels with several pumps, choose our AQUA XL level regulator or our SOBA, TUBA float level switches.
