Description

The PRE-XS is an explosion-proof electric contact pressure gauge designed for hazardous gas environments, capable of measuring media below 70°C and interfacing with explosion-proof electrical devices for automatic control, alarm, and signal transmission. Available in 4″ and 6″ sizes with upright or flush-mount configurations, it covers ranges from −76 cmHg to 1000 kg/cm² with CL 1.6 accuracy. Built with 304/316 stainless-steel construction, it features EC1 snap-action contacts (70% silver, 30% nickel, gold-plated) rated up to 380 V. With IP65 protection and Ex d IIC T6 Gb certification, the PRE-XS is ideal for chemical plants, petrochemical processes, boilers, storage tanks, and other flammable or hazardous applications.
