美国UE双点防爆压力开关H122-358（American UE double point explosion-proof pressure switch H122-358 ）

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. Key Features  The main categories of pressure switches include normally open and normally closed. The main features are: 1. It adopts the British pipe thread quick connector or copper pipe welding installation structure, which is flexible in installation, easy to use, and does not need special installation and fixing. 2. The plug-in wire connection can be selected by the user at will. 3. The sealed stainless steel sensor is safe and reliable. 4. Within the pressure range, it can be manufactured according to the pressure value arbitrarily selected by the user. The application  pressure switch is a device combined with an electrical switch. When the preset fluid pressure is reached, the switch contact will act. It is mainly used in power plants, petrochemical, metallurgical industries and other industrial equipment to output alarm or control signals. Many types of pressure switches in the industry use welded stainless steel diaphragms or welded stainless steel bellows structures, omitting the "O" ring. The leaky design improves fire performance in hazardous explosion-proof areas, while increasing pressure resistance.  Advantages of UE products:  ◆ Complete range 1/ Pressure switch adjustable range from -0.1 to 62MPA 2/ Temperature switch from -50 to 538 degrees Celsius 3/ Differential pressure switch adjustable range from -0.1 to 3.45MPA 3/ Sensing There are three types of components: diaphragm, bellows, and piston 4/ There are switches used in special places, and there are also small and low-cost switches specially designed for OEM users 5/ Both fixed dead zone and adjustable dead zone pressure switch 6/ Some mechanical Differential pressure and temperature switches can be equipped with on-site indication 7/ There are 2-inch pressure port anti-blocking switches and sanitary flat diaphragm switches product is compact in structure, durable, beautiful in appearance and fine in processing. Welded stainless steel design structure
