UE防爆不锈钢J120-493-M2010.06感压孔开关（UE explosion-proof stainless steel J120-493-M201 0.06 pressure hole switch ）

UE switch failure phenomenon: pressure switch has no output signal Reason analysis: (1) The micro switch is damaged (2) The switch setting value is adjusted too high (3) The wire contact connected to the micro switch is not connected properly (4) The pressure-sensitive part is poorly assembled and stuck. (5) The pressure-sensitive element is damaged . Solution: (1) Replace the micro switch (2) Adjust to a suitable setting value (3) Reconnect to make good contact (4) Reassemble , Make the action sensitive (5) Replace the pressure-sensitive element 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 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. It has important uses in the industrial field. It can prevent damage to important devices in production engineering and avoid major production accidents.The working principle of the UE 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 to or When the rated recovery value is raised, 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, diaphragm box and bellows, etc. UE explosion-proof stainless steel J120-493-M201 0.06 pressure-sensing hole switch J120-492-M201 UE0.06 pressure-sensing hole explosion-proof pressure switch (responsibility Editor: )
