About the joint;
Although the price compared with the quality of the product, but the safety factor is a certain difference
Our company advocates safety, precision and stability
The pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the electronic pressure switch can give an alarm or control signal.
The working principle of pressure switch:When the system pressure is higher or lower than the rated pressure of the safety, occurrence of disc instantaneous motion sensors, by connecting rod push switch connector connected or disconnected when pressure drop or rise rated recovery value, disc instantaneous reset, automatic reset switch, or simply when the measured pressure exceeds the rated value when the displacement of the free end of the elastic element, directly or after comparing push switch element, change switch element to control the on-off state of the measured pressure to. The elastic elements used in the pressure switch include single coil spring tube, diaphragm, bellows and bellows. The switch elements include magnetic switch, mercury switch, micro switch, etc..
Main types of pressure switchesIncluding normally open and normally closed type. The main features are:
1 、 adopt BSPT thread fast joint or copper pipe welding type installation structure, flexible installation, easy to use, no special installation and fixation.
2, plug type wire connection can be arbitrarily selected for users.
3. Sealed stainless steel inductor is safe and reliable.
4, the pressure range can be selected according to the user's arbitrary pressure value for manufacturing.
