• Liquid level control

ABB Liquid Level Relay, 0.1 to 1000kΩ Sensitivity, 1 Input - CM-ENS Series - 1SVR730850R0300 CM-ENS.31S

Tired of the ups and downs of tank filling? Level up with this liquid level relay from ABB. It takes the guesswork out of fluid monitoring, as it automatically signals a pump to open when your liquid storage container reaches low levels. The deft device patrols high water points and is easy to set manually using the potentiometer on its front face. A selectable and adjustable on/off delay is on hand to help you overcome nuisance tripping. You can mount this relay in a jiffy by simply snapping it onto a DIN rail.

Features & Benefits

• LED indicator lights for quick and convenient visual diagnostics
• For safety, flame-retardant housing won't catch alight in the event of a fire
• Compact dimensions of 113.4 (L) x 22.5 (W) x 113.4 (D) to maximise board packing efficiency
• Screw terminals hold wires securely so there's minimal need for retightening

Applications

• Waste water management
• Power utilities
• Food and beverage industries
• Pharmaceutical manufacturing

Can I adjust the sensitivity of this liquid level relay?

Yes, the device has an adjustable sensitivity range between 0.1 and 1000kΩ for flexibility.

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
