Differential Pressure Switches/Gauges are ATEX approved.
December 7, 2011 -
Providing both low and high limit control, Series AT23000MR and AT23000MRS Photohelic® Switches/Gauges combine differential pressure switch with analog pressure gage. AT23000MR Series employs electromechanical relays, while AT23000MRS Series uses SPST (NO) solid state relays. Compatible with air and other non-combustible, non-corrosive gases, gauges handle pressures to 25 psig. Flame-proof ATEX enclosures have glass window for viewing set point needles and process pressure.

Series AT23000MR/MRS ATEX Approved Photohelic® Switches/Gages
Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES AT23000MR/MRS ATEX APPROVED PHOTOHELIC® SWITCHES/GAGES.
Using solid state technology, the Series AT23000MR and AT23000MRS ATEX approved Photohelic® switches/gages combine the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage. Gage reading is unaffected by switch operation and will indicate accurately even if power is interrupted. The AT23000MR Series employ versatile electromechanical relays with low amperage ratings- ideal for dry circuits. For applications requiring high cycle rates, choose the AT23000MRS models with SPST (NO) solid state relays. Easy to adjust set point indicators are controlled by knobs located on the gage face (accessible opening case after de-energizing instrument). All models provide both low and high limit control. Compatible with air and other non-combustible, non-corrosive gases, they can be used in systems with pressures to 25 psig (1.725 bar). Optional construction is available for use to either 35 psig (2.42 bar) or 80 psig (5.51 bar) as well as an over pressure relief valve. Flame-proof ATEX enclosures are available with glass window which allows for viewing of set point needles and process pressure.
