UE pressure switch US UE pressure switch J402-533 J402-532 pressure switch working principle When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is pushed through the connecting guide rod to connect. On or off, when the pressure drops or rises to the rated recovery value, the disc resets instantaneously, and the switch automatically resets, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, directly or After comparison, push the switch element to change the on-off state of the switch element, so as to achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on.

The all-weather series pressure switch has a variety of micro switches and a variety of process interface options, so that the 400 series UE pressure switch can meet various needs. It is widely used in protection and control, industrial process equipment, pumps, gas turbines, compressors, etc. Machinery, pulp, paper, water and sewage treatment and other occasions. Features: One, two or three switching outputs, which can be set separately within 100% of the set point . The epoxy resin shell design meets NEMA 4X requirements . A variety of diaphragms are available, such as 316SS, brass, Nitrile and TEFLON Select reference scale or turn screw to adjust set point range Inches of water column range: -300" water column vacuum to 250" water column (-746.7 to 622.3 mbar) Pressure: 30" Hg to 6000 psi Differential pressure : 1" water column differential pressure to 200 psid (0 to 13,8 bar) Temperature: -180 to 650°F (-115°C to 340°C)(Responsible editor: )
