Eagle Explosion-proof Industry Alliance has developed explosion-proof pressure transmitters for the petroleum, chemical, pharmaceutical and other industries. The explosion-proof pressure transmitter is a pressure transmitter suitable for use in hazardous locations and is also suitable for general industrial applications. The pressure core of this product uses laser resistance trimming technology for wide temperature compensation, and has the advantages of high accuracy, small temperature drift, wide operating temperature range, stable performance, and reliable quality. It also has the advantages of multiple ranges, multiple pressure interfaces, and display screen rotation, which is convenient for matching different working conditions.
This product has intrinsically safe type, dust intrinsically safe type and ordinary type to choose from. The intrinsically safe type is suitable for hazardous places in Zone 0, Zone 1 and Zone 2, and Class IC explosive gas environment. The dust intrinsically safe type is suitable for hazardous places in Zone 20, Zone 21 and Zone 22, and Class IIIC conductive dust environment.
■Intrinsically safe, dust intrinsically safe
■High accuracy, small temperature drift
