Pressure switch/gage | range 0-5″ w.c. | .10 minor divisions.
Series 3000MR/3000MRS Photohelic® Switch/Gage
Using solid state technology, the Series 3000MR/3000MRS Photohelic® Switch/Gages combine the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage employing the durable, time-proven Magnehelic® gage design. Switch setting is easy to adjust with large external knobs on the gage face. Gage reading is unaffected by switch operation – will indicate accurately even if power is interrupted. Solid state design now results in greatly reduced size and weight. Units can be flush mounted or surface mounted with hardware supplied. 3000MR models employ versatile electromechanical relays with gold over silver contacts – ideal for dry circuits. For applications requiring high cycle rates, choose 3000MRS models with SPST (N.O.) solid state relays. All models provide both low and high limit control and include 18-inch (45 cm) cable assemblies for electrical connections.
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).
Included Accessories: mounting ring, snap ring; 18″ (45 cm) cable assembly; (2) 3/16″ tubing to 1/8″ NPT adapters; (2) 1/8″ NPT pipe plugs; (4) 6-32 x 1-1/4″ RH machine screws (panel mounting); and (3) 6-32 x 5/16″ RH machine screws (surface mounting).
Please see Series AT-3000MR/MRS for ATEX approved.
