Ashcroft's DDS differential pressure switches feature sensitive elastic elements and heavy-duty containment vessels
Measuring a low differential pressure across a restriction in a high pressure line requires both a sensitive elastic element and a heavily-constructed containment vessel. The Ashcroft DDS-Series differential pressure switch is designed to combine both attributes, enabling it to control differential pressures from 0/6 to 0/150 inches of water on pressure lines up to 1500 psi. UL Listed NEMA 4 water-tight and NEMA 7 explosion-proof versions are available with a choice of electrical switches, wetted materials and setpoint options. Encased in a cast-aluminum housing, DDS pressure switches employ a near frictionless switching mechanism.
