• Choices of Easy connect push in terminals or screw terminals

• DIN Rail mountable - no tooling required

• Easy adjustment using front panel

• Cascadable

• Adjustable response sensitivity

• 1 C/O SPDT output contact

• Compact 22.5 mm width

Additional Features CM-ENS.2

• Control of two levels (MIN/MAX)

• Front panel adjustment of fill and drain function

Additional Features CM-ENS.31

• Control of two levels (MIN/MAX)

• Front panel adjustment of fill and drain function

• 2 C/O SPDT Contacts

• Selectable ON / OFF delay

Applications

• Dry running protection

• Overflow protection

• Liquid level control

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.

Application Examples

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
