Using solid state technology, the SERIES 3000MR Photohelic Switches/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 the 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.

FEATURES/BENEFITS:

  • Gage reading unaffected by switch operation and will continue to read pressure even during power loss
  • Zero and range adjustments outside of gage means no disassembly in normal service
  • Solid state design allows for switching in high cycle rate applications without degradation
  • Optional stainless steel bezel is the same installation diameter as Magnehelic gage and simplifies field upgrade to Photohelic switch/gage

APPLICATIONS:

  • Pneumatic conveying
  • Air conditioning systems
  • Clean rooms
