CM-ENS Liquid Level Relays

A series of liquid level control relays from ABB for conductive liquids. The CM-ENS range gives a choice of 3 variants each with a compact, space saving housing with the highest fire protection and environmentally friendly materials. Installation is quick and easy using screw or easy-connect terminals and tool free DIN Rail mounting.

Features and Benefits (CM-ENS.1 / CM-ENS.2 / CM-ENS.3)

• 3 LED operational state indication

• 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

ABB Liquid Level Relay, 5 to 100kΩ Sensitivity, 1 Output - CM-ENS Series - 1SVR730850R0100 CM-ENS.11S

Control the ebb and flow of your tank levels with this liquid level relay from ABB. It stops pumps from running on empty or overflowing, so there's no need for you to manually check them. EMC immunity means you can use this monitoring unit in harsh locations with minimal risk of interference from nearby electronic devices. To keep you in the loop, its three LED indicators let you quickly assess its operating status. The relay simply snaps onto a DIN rail for stress-free mounting or removal.

Features & Benefits

• Flame-retardant housing so there's no chance of it contributing to a fire
• Adjustable measurement sensitivity between 5 and 100kΩ for versatility
• Compact housing with a width of 22.5mm, for control-board packing efficiency
• IP50-rated housing indicates it's protected against dust particles

Applications

• Breweries
• Medical and pharmaceutical industries
• Heater treaters
• Contact towers

Can I use this relay to monitor both high and low liquid levels?

Yes, if you use this relay with another unit from ABB's CM-ENS range such as an electrode (746-7514), it's possible to monitor levels in a tank from normal to extreme.

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
