The cost-effective 24 Series Delta-Pro™ differential pressure switches offer a unique blend of compact size, excellent performance, and environmental protection. Available with brass or polysulfone pressure connections, the Delta-Pro is ideal for applications involving hot or cool air, water, gas or oil. The precision snap-acting switch and sensitive diaphragms combine to provide a narrow deadband and repeatability of approximately ±1% of full scale range. A convenient, externally accessible adjustment screw is multi-turn to provide easy set point adjustability. force-balanced design gives...

applications Typical applications include filter monitoring and proof-of-flow. The 24 Series is used within the water & wastewater, bioprocessing, food & beverage, HVAC and gas processing industries. GASKETED STAINLESS STEEL COVER STRONG, CORROSIVE RESISTANT POLYESTER ENCLOSURE PRECISION SNAP-ACTING SWITCH N.O., N.C., COM SCREW TERMINALS (SPDT) EXTERNAL ADJUSTING SCREW CLEARANCE HOLES FOR #6 SCREW FOR SURFACE MOUNTING IN ANY POSITION The 24 Series (Delta Pro™) was designed to be a compact, cost-effective differential pressure switch for applications such as proof-of-flow, filter monitoring,...

specifications AMBIENT TEMPERATURE 30° to 160°F (-1° to 71°C). Set point typically shifts less than ±0.6% of range for a 50°F (28°C) ambient temperature change; consult factory for special ratings Set point repeats after 15G, 10 millisecond duration Set point repeats after 2.5G, 5-500 Hz Complies with enclosure type 4 requirements for indoor installation with optional water tight conduit connector. Reinforced polyester body, stainless steel cover with gasket. Typically ± 1% of full scale range. SWITCH OUTPUT One SPDT snap-action switch; switch may be wired "normally open" or "normally...

RECOMMENDED PRACTICES AND WARNINGS United Electric Controls Company recommends careful consideration of the following factors when specifying and installing UE pressure and temperature units. Before installing a unit, the Installation and Maintenance instructions provided with unit must be read and understood. • To avoid damaging unit, proof pressure and maximum temperature limits stated in literature and on nameplates must never be exceeded, even by surges in the system. Operation of the unit up to maximum pressure or temperature is acceptable on a limited basis (e.g., start-up, testing)...
