The CM-ENS.13S belongs
to the CM liquid level monitoring relay range. It operates with a rated control
supply voltage of 110-130 V AC and 220-240 V AC and has a 1 c/o (SPDT) output
with contacts rated at 250 V / 4 A. It monitors liquid levels of conductive
fluids and protects pumps against dry running or tanks against overflow and
works according to the open-circuit principle. The sensitivity can be selected
via front-face potentiometers. Several electrodes and a sealable transparent
cover for protection against unauthorized changes are available as accessory.
The device offers screw connection technology with double-chamber cage
connection terminals.
