United Electric H100-190 SPDT Differential Pressure Switch 5-30 PSI NEMA 4

The United Electric H100-190 is a heavy-duty differential pressure switch designed for demanding industrial applications. Part of United Electric's trusted H100 Series, this switch monitors the difference in pressure between two points in a system and actuates when the differential pressure reaches the set point within its 5–30 PSI differential range.

Key Features:

• SPDT (Single Pole Double Throw) switching action for versatile circuit control — normally open or normally closed configurations
• 5–30 PSI differential pressure range for precise set point adjustment across a wide operating window
• NEMA 4 rated enclosure — provides protection against windblown dust, rain, splashing water, and hose-directed water; suitable for indoor and outdoor use
• Rugged construction built to withstand harsh industrial environments
• Field-adjustable set point for easy on-site calibration
• Reliable snap-action switch mechanism for consistent, repeatable performance

The H100-190 is a dependable solution for HVAC systems, filter monitoring, pump and compressor protection, flow detection, and general process control applications where differential pressure monitoring is required.
