Differential pressure switch J21K American UE switch J21K   Differential pressure switch J21K American UE switch J21K working principle  The differential pressure switch is composed of two bellows chambers, and the two chambers are respectively sealed by two sealing diaphragms and a differential pressure sensing diaphragm. The high pressure and low pressure respectively enter the high pressure chamber and low pressure chamber of the differential pressure switch, and the differential pressure sensed deforms the pressure sensitive diaphragm, and through mechanical structures such as railing springs, the uppermost micro switch is finally activated to output electrical signals.   J21K series UE differential pressure switch - metal bellows sealed durable differential pressure switch welded 316 stainless steel sensor, completely airtight housing, single switch output, adjustable range: 30 inches Hg vacuum to 90PSID; applied to the filter of the compressor network monitoring; refrigeration equipment (chillers); fluid calibration; water treatment and filtration systems; HVAC equipment. The following are the main features of UE J21K series differential pressure switch : .Adjustable differential pressure from -1 to 6bar  . Reliable sealed metal bellows sensor  . Welded 316 stainless steel type .Epoxy resin shell design meets NEMA4X requirements .Set point repeatability plus or minus 1% Differential pressure switch J21K American UE switch J21K   Differential pressure switch J21K American UE switch J21K
