The SOR weatherproof pressure switch is the lower-cost alternative to the explosion-proof model. It employs two discrete sensing assemblies that provide independent, adjustable, fine-resolution set points that can be calibrated to the same actuation point or split to the full span of the adjustable range without interaction.

The Dual Hi-Lo is popular for use in alarm systems configured to signal at a minimum and/or maximum pressure. The V1 is field adjustable, making it a convenient choice for a wide variety of applications.

  • Dual set points
