UE開關J400-551J402-551J403-551UE（UE national agent [J400-551 J402-551 J403-551] UE Teflon diaphragm pressure switch ）

UE national agent【J400-551 J402-551 J403-551】UE Teflon diaphragm pressure switch J400-551 0~19.91KPa 1*SPDT Teflon diaphragm Vtion O-ring pressure port 1/4NPT inner wire stainless steel port 316L material maximum pressure 0.2bar J402-551   0~19.91KPa   2*SPDT Teflon diaphragm Vtion O-ring pressure port 1/4NPT inner wire stainless steel port 316L material maximum pressure 0.2bar J403-551   0~19.91KPa   3*SPDT Teflon diaphragm Vtion O-ring pressure interface 1/4NPT inner wire stainless steel interface 316L material maximum pressure 0.2bar The mechanical pressure switch is a purely mechanical deformation that causes the action of the micro switch. When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will be deformed and will move upwards. Through the mechanical structure such as the railing spring, the uppermost micro switch will be activated to output the electrical signal. Control the pump start and stop  switch to control the start and stop of the pump. In the process, the pump is generally used as a power source to control the pressure in a specific area within the (a, b) interval, and the switch outputs a switching signal whether it reaches point a or b.  Option 1: H100-15731~15737, adjustable dead zone, SPDT output, the opening and closing of the switch point can directly control the start and stop of the pump. Disadvantage: no stock, the set point is easy to drift up to 10% of the set point. On-site calibration capability is required. Advantage: there is no need to add a logic controller in the middle, and there will be no switch point dead zone > ba range. question.  Option two: J402, 2 SPDT outputs. Disadvantage, it is necessary to add a logic relay to output signals when two points act at the same time. Advantage: no drift when ba>c.UE pressure switch Features: ·One, two or three digital outputs, can be set separately within 100% of the set point ·Single point or multi-point setting is optional ·Epoxy resin shell design meets NEMA 4X requirements ·Multiple Diaphragm options 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 6000psi Differential Pressure: 1" water column to 200 psid (0 to 13,8 bar) Temperature: -180 to 650°F (-115°C to 340°C)
