New Series AT3A3000 ATEX Approved Photohelic® Switch/Gage
Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES AT3A3000 ATEX APPROVED PHOTOHELIC® SWITCH/GAGE.
Flame-Proof ATEX approved Photohelic® switch/gage, Series AT3A3000, function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Photohelic® switch/gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 psig (2.4 bar) or 80 psig (5.5 bar). Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face (accessible opening case after de-energizing instrument). Set points can be interlocked to provide variable dead band - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Series AT3A3000 Flame-proof ATEX enclosures are available with glass window which allows for viewing of set point needles and process pressure.
