The Dwyer Series 1900 (Model 1910-00) is a compact low differential pressure switch engineered for precise switching in low-pressure applications such as HVAC airflow monitoring, filter status detection, and clean-room pressure control. Its durable housing and conduit connection make it well suited for industrial and commercial environments.
Featuring a narrow operating range of 0.07–0.15" WC, this switch delivers reliable, repeatable performance where accurate low differential pressure sensing is critical. The compact form factor simplifies installation in space-constrained panels and ductwork enclosures.
