Pressure sensor in the production process has a wide application. The main reason is pressure sensor can directly show the pressure variation of each working procedure, insight into products or medium flow conditions, the trends of safety monitoring of the production process and through the automatic chain or sensing devices, build the a quick and reliable security, to prevent accidents, protect the personal and property safety play an important role, is called safe "eyes".

Pressure sensor is too small compared with the production system, and it does not have any danger itself. But by the use of a pressure sensor as the main body, with automatic interlocking device, sensing device, protection device based on, to slender subtle perception for visual and on safety construction of fort is irreplaceable.

As one of the safety accessories of the pressure sensor, the time to protect the product safety, personal safety, environmental safety of the door. Especially in the use of flammable, explosive, toxic substances in the production, storage, transportation and other dangerous places, the pressure factor on the prevention of catastrophic accidents, the key role. So the great contribution to security in sensor pressure sensor. Of course, this also requires that we must ensure that the accuracy and stability of the pressure sensor, the only way to give full play to its role in the production process.
