Explosion Proof Differential Pressure Switches

Dual Opposed Diaphragm – Explosion Proof Differential Pressure Switch

Hermetically Sealed Differential Pressure Switches

Weatherproof Differential Pressure Switches

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.
