3003MRS

Product Highlights Using solid state technology, the Series 3000MR and 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 in 4-13/16" (122 mm) 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 Provides both low and high limit control and include 18-inch (45 cm) 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 (1.725 bar) Each Unit Includes 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) (3) 6-32 x 5/16" RH machine screws (surface mounting)
