1、 Application background

2、 Working principle

The micro pressure sensor collects real-time pressure difference data and transmits it to the main control unit. The main control unit controls the air valve actuator and enhances the fan to achieve air exchange rate and air supply volume in real time according to preset parameters. It establishes a gradient pressure difference indoors and perfectly achieves the isolation effect of negative pressure wards, effectively preventing cross infection of patients and protecting medical staff.

3、 Product Features

1) Control range: can be set by oneself and automatically controlled by the system;

2) Differential pressure detection accuracy: 1%, high configuration can reach 0.5%;

3) Environmental data collection; Exceedance alarm

4) It can achieve 12 times/hour automatic ventilation, and the ventilation frequency can also be set by oneself;

5) Disinfection and sterilization realizes human-machine coexistence;

6) It can achieve remote monitoring, precise positioning, and facilitate overall scheduling and deployment.

4、 Application scenarios

1）Transportation areas such as subway stations, train stations, airports, and highway intersections

2）Customs entry and exit

3）Centers for Disease Control and Prevention, hospitals, community health service centers, street offices
