Description
The United Electric H100-702 differential pressure switch is a rugged, field-adjustable control designed for monitoring pressure differences in HVAC, fluid handling, and industrial process systems. With an adjustable differential range of 3 to 100 PSI, this switch provides reliable performance for applications such as filter monitoring, flow verification, and system protection. The SPDT (single-pole, double-throw) contact configuration allows for flexible control of normally open and normally closed circuits. Housed in a NEMA 4-rated enclosure, the H100-702 offers protection against water and dust, making it suitable for demanding indoor and outdoor environments.
