Solid-State Level Switches 840E • Piezoelectric effect technology • Rugged, corrosion-resistant stainless steel housing and sensing element • DC Micro (M12) and DIN valve connection types • Highly-visible status LED for process monitoring • Complementary N.O./N.C. outputs • Operation independent of the medium properties – build up, changing media, turbulence, air bubbles, foam, and vibration • Reliable Level Detection Regardless of Media Characteristics • Allen-Bradley level sensors are a quick and easy solution for applications requiring point level detection. • These sensors have been applied in applications such as liquid level monitoring in tanks, containers, and pipes. • The 840E stainless steel liquid level sensors are capable of detecting corrosive liquid media and operate independently of the media properties such as liquid build up on the forks, change of media structure, turbulence, foam or air bubbles as well as plant vibrations. • The 840E switch uses piezoelectric effect technology to see the difference in vibration when the medium is sensed on the forks. • The use of alternating voltage current causes the piezo to expand and contract. • The difference in vibration oscillation detected by the medium indicates the presence of the medium.
