Winters Instruments 7WPSDO Series Pressure Switch 7WPSDO

Description & Features:• High pressure seals are opposed stainless steel bellows assemblies, while the differential pressure is sensed by a diaphragm clamped between these bellows assemblies• Diaphragm has a large area to accurately sense low differen tial pressure. During over-pressure the diaphragm is fully supported• 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• Rugged cast aluminum housing incorporates Winters' standard accurate switching mechanism, and can be specified watertight or explosion proof• Housing is large enough to accommodate up to four full size SPDT electric switches• 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• 1 year warrantyApplications : • Designed to sense low differential pressures between high pressure sources
