SOR 17RB-AA2-N4-D1A Pressure Switch

SOR 17RB-AA2-N4-D1A is a weatherproof differential pressure switch in the 17RB family, engineered to detect small pressure differences and trigger an electrical change when a preset differential pressure is reached. It specifies a 4–15 psid sensing range, enabling precise monitoring of airflow or process-line pressure differences in systems such as air-handling ducts, filtration stages, and other low-differential applications where reliable switch action is essential. Housed in a weatherproof enclosure designated NEMA 4 for protection against dust, water, and washdown conditions, this model is designed for use in challenging industrial environments and potentially outdoor installations. It provides a straightforward electrical signal to control panels or interlocks when the differential pressure reaches the setpoint, supporting integration with safety interlocks and control sequencing in HVAC and process-control applications. Typical applications include monitoring duct pressure across filters and maintaining differential pressure in process lines to protect equipment and indicate maintenance needs.
