National Supply of Liquefied Gas Gas Detectors

Operation Principle: The detectors installed on-site are powered by the controller. In the event of a gas leak, the RBK-6000-ZL9 type Combustible Gas Alarm Controller converts the leak amount into a corresponding voltage signal for output. After processing by the detector, the voltage signal is uploaded to the controller, which receives the data, parses it, and displays it on the screen. When the concentration reaches the set trigger value, the controller triggers an alarm and drives external devices.
