3 Overview

The detection alarm is used to detect the concentration of carbon monoxide gas in the mine operating environment. When the concentration of carbon monoxide gas When the alarm setting value is exceeded, the sound and light alarm signals can be automatically generated. The detection alarm is mainly composed of a carbon monoxide electrochemical sensor, electronic components and a display part, and is electrochemically transmitted. The sensor converts the concentration of carbon monoxide gas in the environment into an electrical signal, which is then processed by electronic components and used as a concentration value. display. Depending on the mode of use, the detector alarm can be divided into portable (mine industry is known as alarm meter or measurement) And fixed type (known in the mining industry as a sensor). The stationary detection alarm also has a signal corresponding to the concentration Output function. According to the characteristics of the detection alarm, key components and materials should be clarified. The format is shown in Table 1.
