Accuracy, multi-use flexibility and the ability to match the instrument to the application distinguish SOR differential pressure switches from off-the-shelf products. Standard differential switches are available in weatherproof and explosion-proof configurations and can include an external setpoint adjustment mechanism for simplified calibration. SOR differential pressure switches are suited for a wide range of applications from filter maintenance to high static pressure flow monitoring.

 

Versatile designs engineered for a wide variety of applications

  • Draft range to high working pressure ranges
  • Multiple sensor designs
  • Adjustable set points with a calibrated scale
  • Negligible temperature and/or static influence
