SOR Controls Group Dual Hi-Lo Pressure Switches are weatherproof V1 pressure switches for applications that require two pressure set points in one pressure-switch configuration.
The design uses two discrete sensing assemblies to support independent, adjustable, fine-resolution set points.
These pressure switches can be used where minimum and/or maximum pressure signaling is required.

Process Controls Corporation supplies SOR Dual Hi-Lo Pressure Switches for industrial customers who need weatherproof pressure switch options with calibrated scale set point adjustment.
