UE压力开关J403-554三点控制压力开关的原理（US UE pressure switch J403-554 three-point control pressure switch principle ）

The principle of three-point control pressure switch of American UE pressure switch J403-554  industrial application Multi-point switching output for alarm and shutdown or pre-alarm and alarm High/low limit control or liquid level control Water Treatment and Filtration Systems industrial sterilizer Pump Systems and Compressors Ideal maintenance for numerous other industrial projects and equipment working principle The working principle of the pressure switch: 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 connected or disconnected by connecting the guide rod. When the pressure drops or rises When the rated recovery value is reached, the disc resets instantaneously and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the switch element. On-off state 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. performance options European ATEX intrinsically safe standard Remote temperature switch can choose 50 feet copper or stainless steel capillary, armored protection cable is optional Multiple switching output options including manual reset, adjustable deadband, DPDT The red mark shows that the current switch is set Measuring Range of 400 Series UE Switches 1. inch water column range - 300" water column vacuum to 250" water column (-746.7 to 622.3mbar) 2. Pressure: 30"Hg to 6000psi 3. Pressure difference: 1 "water column pressure difference to 200psid (0-13.8bar) 4. Temperature: -180 to 650℉ (-115-340℃)
