UE 24 Series Delta-Pro Differential Pressure Switches
Cost-effective differential pressure switch with external adjustment. Diaphragm sensor and snap-action switch, single SPDT switch outputs, NEMA 4 enclosure general service environments. UL, cUL, ATEX, and IECEx approvals, CE compliant.
United Electric's Delta-Pro differential pressure switch offers a unique blend of small size, excellent performance, environmental protection, long life mechanics, and an attractive price. The precision snap-acting switch and sensitive diaphragms combine to provide a narrow deadband and one-percent span repeatability.
Available with brass or Polysulfone pressure connections, the Delta-Pro will stand up in the most corrosive applications. A convenient, externally accessible adjustment screw is multi-turn to provide easy set point adjustability. Typical Delta-Pro applications include filter monitoring and proof-of-flow in wastewater, bioprocessing, food and beverage, HVAC, and gas processing industries.
