LFM751 Low Differential Pressure Transmitter can be used in hazardous situations. It has a cast aluminum housing and high level of protection. It is suitable for various complex industrial conditions, such as natural gas pipeline monitoring, power plant air supply system, and pharmaceutical factory clean engineering. It adopts high-precision imported MEMS micro-pressure sensing cell, with characteristics of fast pressure response, stable long-term output, superior temperature performance, convenient installation, and strong electromagnetic interference resistance. Two models available: intrinsically safe explosion -proof and intrinsically safe dust explosion-proof. Intrinsically safe explosion-proof can work in Zone 0, 1, and 2, and intrinsically safe dust explosion-proof can work in Zone 21 and 22.
Intrinsically safe, and Dust Explosion-proof certification.
Cast aluminum shell, protection grade IP65.
Reverse polarity protection, stable performance.
CE Certification.
