ABB Liquid Level Relay - DIN Rail Mount, Screw Mount, Snap-On, 24 V ac

ABB Up/Down Liquid Level Relays are specifically designed to monitor the filling and draining of liquid levels within tanks. The units offer a switchable function (for filling or draining selection). Overflow or dry-running protection is also a selectable option. The units work by measuring the change in resistance sensed by a single-pole electrode.

Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use.

Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the:

Monitoring and control of liquid levels
Protection of pumps against dry running
Ability to detect liquid leaks in a system
Control of media mixing ratios
Control of liquid levels
