Fire resistant endorsed Series AT3A3000ATEX/IECEx Approved Photohelic Switch/Gage with 120, 240 or 24 VAC Power capacities as flexible, profoundly repeatable tension switches joined with an exact strain gage utilizing the well established Magnehelic gage plan.
ATEX/IECEX APPROVED PHOTOHELIC SWITCH/GAGE
WITH 120, 240 OR 24 VAC POWER
Photohelic Switch/Gages in Flame-Proof ATEX/IECEx Enclosures
The Photohelic switch/gage measures and controls positive, negative or differential tensions of air and viable gases. Standard models are evaluated to 25 psig (1.7 bar) with choices to 35 psig (2.4 bar) or 80 psig (5.5 bar). Two phototransistor incited, DPDT transfers are incorporated for low/high cutoff control. Simple to change set point markers are constrained by handles situated on the gage face (available opening case after de-invigorating instrument). Set focuses can be interlocked to give variable dead band-ideal to control of fans, dampers, and so forth. Gage perusing is consistent and unaffected by switch activity, in any event, during loss of electrical power. Fire resistant fenced in areas are accessible in aluminum with glass window which considers survey of set point needles and cycle pressure.
