UE national agent【J400-554 J402-554  J403-554】UE Teflon diaphragm pressure switch J400-554 0~2.1bar 1*SPDT Teflon diaphragm Vtion O-ring pressure port 1/4NPT inner wire stainless steel port 316L material maximum pressure 0.2bar J402-55 4 0~2.1bar  2*SPDT Teflon diaphragm Vtion O-ring pressure port 1/4NPT inner wire stainless steel port 316L material maximum pressure 0.2bar J403-55 4 0~2.1bar   3 *SPDT Teflon diaphragm Vtion O-ring pressure interface 1/4NPT inner wire stainless steel interface 316L material maximum pressure 0.2bar  Industrial application of UE switches z used in the implementation of alarm, activation and shutdown of dangerous device switches, vacuum switches, differential pressure switches and temperature switches in the following fields: chemical plants; oil pipelines; oil refineries; coal dust and grain dust treatment; pure gas Pipeline; gas buffer system; storage tank and pressure pump, compressor and steam turbine  control 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. 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.   US UE Switch Performance Options z Variety of micro switches to choose from: 1 amp to 30 amps and up to 480 VAC  z single pole double throw and double pole double throw and hermetically sealed switch z adjustable dead zone z External manual reset z Hastelloy., Monel. and sensor materials suitable for corrosive media z 150# and 300# flanges z The temperature switch can choose capillary length and armored stainless steel or TFE coating according to customer requirements to protect capillary and temperature package z Optional stainless steel temperature bulb, external reference scale type, fully sealed type, chain box cover, thermocouple casing, etc.
