SERIES AT3A3000 ATEX/IECEX APPROVED PHOTOHELIC SWITCH/GAGE WITH 120, 240 OR 24 VAC POWER

PublishTime：2021-12-13

●Flame-proof approved Series AT3A3000 ATEX/IECEx Approved Photohelic® Switch/Gage with 120, 240 or 24 V-AC Power functions 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. Flame-proof enclosures are available in aluminum with glass window which allows for viewing of set point needles and process pressure.
●FEATURES/BENEFITS:
■ 3-in-1 ATEX/IECEx approved instrument allows the reduction of several instruments with one product, saving inventory, installation time and money
■ Flame-proof enclosure with optional glass window and aluminum housing protects the device in hazardous areas while giving local visibility to process pressure and set point status
