The Dwyer® Series AT-3000MR/MRS ATEX/IECEx approved Photohelic® switch/gage incorporates a flameproof aluminum enclosure that protects the device for use in hazardous areas commonly found in process or industrial applications.
The 3000MR/3000MRS Photohelic® switch/gage, contained in the Series AT-3000MR/MRS, is designed for monitoring pressure, vacuum, and differential pressure. Solid-state switches allow for switching in high cycle rate applications while extending the life of the sensor. These products can be installed in varying process or HVAC applications globally because of the numerous pressure ranges and units available.
Well-suited for industrial applications, the Series AT-3000MR/MRS incorporates a cast aluminum enclosure with texture epoxy coating. It also features a standard windowed enclosure cover that allows users the ability to visually verify changes in the process.
