Differential pressure switch released by Ashcroft
The DDS Series differential pressure switch released by Ashcroft is made to sense low differential pressures between high pressure sources.
May 31st, 2013
Many times, 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 DDS 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.
