High Static, Low DP Switch


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 new Ashcroft® DDS-Series differential pressure switch combines 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 for superior repeatability.
