How do PVC high speed roll-up door air flow sensor work ?

Since the airbag sensor/air flow sensor becomes one of the safety standard configuration of the fast shutter door,

the airbag also needs to be used reasonably, so on this premise we must have a knowledge of it. In all the safety configurations of the fast door, the airbag is a barrier to operation, and it acts a quite important role on the High Speed Door automation system.

Here let`s introduce, what kind of existence is the airbag sensor and what role does it act?

Airbags sensor/air flow sensor+ infrared rays safety sensor are installed in the daily production of rapid roll-up shutter doors. An airbag system is a passive safety device that works in conjunction with infrared to provide effective crash protection for personnel.

During operation, when the door encounters an obstacle, and during the falling process, you will find that the air pressure of the airbag will change, the door will stop falling immediately, and run upwards in the opposite direction until the door stops at the open position.

Through this incident, it can be clearly seen that the function of the airbag sensor is to ensure the safety of the fast door body during the fall process, and to avoid people under the door body falling, which will hurt people or cause safety accidents.

In fact, security issues are closely related to our lives. Safety accidents are really close to us, and most of them are caused by careless, illegal operation and other reasons.

As long as we pay more attention, be serious, and be careful, many accidents could be avoided, at least the incidence of safety production accidents will be greatly reduced. Strengthen the study of various safety common sense, and improve self-protection awareness. Remember that safety is all around me and keep "danger away from us".
