Reliability in the harshest conditions

Our Allen-Bradley Condition Sensing family introduces the new 840E solid-state level switch to its already successful product line. Our applications knowledge together with our technical expertise in the level switch condition sensing business enables us to help you find the ideal solution for all your application needs.

The compact 840E level switch is based on piezoelectric vibrating fork technology. The level switch monitors resonance frequency and indicates whether the tuning fork is freely vibrating or covered by liquid. With its IP66/67 rating, the 840E performs reliably in the harshest of environments, including turbulence, vibration, content build-up, changing media, and bubbles and foam.

Applications and Industries
Housed in rugged, corrosion-resistant 316L stainless steel enclosure, this cost-effective compact level switch is suitable for most fluid applications including:
• Liquid level monitoring
• Tanks, containers and pipelines
• Filtering systems
• Coolant and lubricant tanks
• Pump protector program support

Utilised primarily for liquid level detection in industries such as factory automation, oil and gas, chemical, food and beverage and automotive, this level switch is easy to install and has no moving parts, so it is virtually maintenance-free. Plus, the 840E can be mounted in any orientation – top, bottom, sideways, or even in pipe work.

The 840E is available in a DC PNP version with a M12 connector or an AC version with a DIN valve connector.
