Dwyer 3001MR Photohelic Differential Pressure Switch/Gauge Range: 0-1"w.c.
Pressure switch/gage, range 0-1"w.c..02 minor divisions.
Combine the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gauge employing the durable, time-proven Magnehelic® gauge design. Versatile electromechanical relays with gold over silver contacts - ideal for dry circuits.
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.
