JKB-R2Bd is a combustible gas detector and alarm that can be used to detect CH4, C3H8 and other combustible gases. The working principle is catalytic combustion. The detector converts the combustion gas concentration at the monitoring point into an electric voltage signal, then converts it into a digital signal, and transmits it to the controller via the bus. The controller calculates, analyzes, and displays the combustible gas concentration at the monitoring point and the working status of the detector. When the detector's sensor element is short-circuited or open-circuited, the detector can send a fault signal to the controller.
