Differential-pressure gages are protected in hazardous areas

| By Mary Page Bailey and Gerald Ondrey

The AT-2000 Magnehelic differential-pressure gage (photo) is ATEX/IECEx approved and incorporates a flameproof aluminum enclosure with textured epoxy coating that protects the device for use in hazardous areas commonly found in chemical processing or other industrial applications. The AT-2000 gage is designed for monitoring pressure, vacuum and differential pressure. Due to the mechanical design of the gage, there is no need for local power to monitor pressure changes. The AT-2000 includes a standard windowed enclosure cover that allows users the ability to visually verify changes in the process. — Dwyer Instruments, Inc., Michigan City, Ind.
