Description Dwyer AT3A3000 Photohelic Switch/Gages functions as versatile, highly repeatable pressure switches combined with a precise pressure gauge 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 […]
Description Dwyer AT23000MR/3000MRS Photohelic 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. AT23000MR series employ versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high […]
Description Dwyer 43000 Capsu-Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Capsu-Photohelic® switch/gage employs an encapsulated sensing element for use with both liquids and gases at pressures of 500 psig (34 bar). Optional cast brass case is available for water or […]
