      Differential Pressure Switches weatherproof or explosion proof

      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 set point 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.
