Integrated gas detector integrating with audible and visual alarms

Abstract

An integrated gas detector integrating with audible and visual alarms, comprising: an explosion-proof housing; a gas detection unit disposed in the explosion-proof housing and used for detecting the concentration of gas; and a signal transducing unit disposed in the explosion-proof housing and used for receiving and processing the signal indicating the concentration of gas from the gas detection unit. Wherein, the explosion-proof housing comprises a cylinder shaped upper cover (23) having an annular inward flange (231). The signal transducing unit and the gas detection unit are located at the two sides of the annular inward flange (231), and lean against the upper surface and the lower surface of the annular inward flange (231) respectively, and are connected detachably and fixedly to each other by a fastening device. The integrated gas detector integrating with audible and visual alarms further comprises a visual alarm unit and an audible alarm unit; the visual alarm unit being disposed at the side of the signal transducing unit; the audible alarm unit being disposed at the side of the gas detection unit; and when the signal transducing unit judges, basing on the signal indicating the concentration of gas, that the concentration of gas exceeds a preset alarm value, the visual alarm unit and the audible alarm unit will be triggered. The gas detector has such advantages as small size, low cost, corrosion-resistance and full functionality.
