Positive pressure system controller

正压系统控制器

Product characteristics

1. The shell is welded with carbon steel or stainless steel, which is firm and reliable. Carbon steel shell surface high voltage electrostatic spray treatment; 2. The control system adopts PLC programmable logic controller, stable and reliable, fast response;

3. Humanized human-machine interface, LCD text display, sound and light alarm, panel button, indicator light and other content;

4. With communication interface, remote centralized monitoring and control can be realized;

5. Real-time monitoring of positive pressure chamber pressure, flow and other important parameters;

6. The sensor signal type and signal value range can be set;

7. The delay time before the formal air exchange can be set to ensure that the combustible gas is completely replaced before the positive pressure chamber is energized;

8. According to the onsite air pressure, the working pressure range, alarm pressure range and positive pressure chamber power cut-off pressure range can be set by themselves

9. Modular program design, just load different programs to achieve different control functions;

10. With system fault analysis program, and in the man-machine interface to flash text prompt users, easy maintenance;

11. There are two processing types of dilution flow and leakage compensation;
