24 Series UE pressure Switch
The cost-effective 24 Series Delta-Pro™ pressure, vacuum, and 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. The force-balanced design gives the Delta-Proexcellent vibration resistance.
Storage temperature -20° to 180°F (-29° to 82°C)
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
max media temperature 200°F (93°C) at 100 psi working pressure
Shock Set point repeats after 15G, 10 millisecond duration
Vibration Set point repeats after 2.5G, 5-500 Hz
EncloSure claSSification Complies with enclosure type 4 requirements with optional water tight conduit
connector. Reinforced polyester body, stainless steel cover with gasket.
Set point repeatability Typically ± 1% of full scale range.
Switch output One SPDT precision snap-acting micro-switch with mechanical contact life of 10
million cycles. Actual life depends on electrical load and cycle frequency
