Model 6PSDO
Solon Model 6PSDO
Differential Pressure Switch, Diaphragm Sensing Element
The Model Series 6PSDO Differential Pressure Switch is designed to sense low differential pressures between high pressure sources. The high pressure seals are
opposed stainless steel bellows assemblies, while the differential pressure is sensed by a diaphragm clamped between these bellows assemblies. The diaphragm has a large area to accurately sense Low Differential Pressure, and during an over-pressure the diaphragm is fully supported. The design is symmetric such that both the HIGH or LOW pressure sides of the element can withstand the maximum pressure with the opposite side at atmospheric pressure. The rugged cast aluminum housing incorporates Solon's standard "frictionless" switching mechanism, and can be specified 6PSWDO, watertight; or 6PSXDO, explosion proof. The housing is large enough to accommodate up to four full size S.P.D.T. electric switches. The standard differential pressure-sensing element is constructed of a strong aluminum alloy using a Buna N elastomer diaphragm. Other diaphragm and wetted area materials are available.
