ABB Liquid Level Relay, 0.1 to 1000kΩ Sensitivity, 1 Output - CM-ENS Series - 1SVR730850R0200 CM-ENS.21S

You won't feel drained by tank management if you use this liquid level relay from ABB. It controls and regulates liquid levels and you can use the handy device for either overfill or dry-running protection. Simply select the up or down function on the front face of its potentiometer for snappy manual setting. You can tune into its awareness, thanks to adjustable response sensitivity that ensures its accuracy is spot-on. There's little chance of this relay gathering dust, as its IP50-rated housing is protected against airborne contaminants.

Features & Benefits

• Flame-retardant housing so there's no chance of it catching alight in the event of a fire
• Screw terminals for simple wiring with a screwdriver
• EMC immunity provides protection against interference from nearby electronic devices
• Snaps onto a DIN rail for quick and easy installation or removal

Applications

• Bottling plants
• Oil and gas industry
• Well test systems
• Reboilers

What's the expected lifespan of this liquid level relay?

The durable component has a mechanical lifespan of up to 10 million switching cycles so you can rely on its longevity.

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
