Description
The United Electric H100K-544 differential pressure switch is a low-pressure, field-adjustable control designed for precise monitoring of air and gas systems in HVAC and industrial applications. With an adjustable differential range of 2 to 20 inches of water column (in. W.C.), this switch is ideal for applications such as airflow proving, duct static pressure control, and filter condition monitoring. The SPDT (single-pole, double-throw) contact configuration allows for flexible control of normally open and normally closed circuits. The epoxy-coated NEMA 4 enclosure provides enhanced protection against water, dust, and corrosion, making it suitable for demanding indoor and outdoor environments.
