Dwyer 3000MR-00 Photohelic Differential Pressure Switch/Gauge
Pressure Switch/Gage, Range 0-0.25" w.c., .005 minor divisions.
Series 3000MR PhotohelicÂ® Switch/Gage, Additional Range 0-0.25" w.c., Relay Type - Electromechanical Relays
The Series 3000MR PhotohelicÂ® 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 MagnehelicÂ® 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 Â±2% of full scale and switch repeatability is Â±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.
