Series 3000MR Photohelic Switch/Gage

Series 3000MR Photohelic® Switch/Gage, Additional Range 0-60 Pa, Relay Type - Electromechanical Relays Includesmounting ring, snap ring 18' 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) (3) 6-32 x 5/16' RH machine screws (surface mounting)The Series 3000MR Photohelic® Switch/Gage 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 in 4-13/16" hole 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. Model provide both low and high limit control and include 18-inch cable assemblies for electrical connections.Gage accuracy is ±2% of full scale and switch repeatability is ±1%. Switch deadband is one pointer width - less than 1% of full scale. Compatible with air and other non-combustible, non-corrosive gases, they can be used in systems with pressures to 25 psig.
