Detailed Description

GJD100G High concentrations of gas sensors GJD100G High concentrations of methane sensor (hereinafter referred to as the sensor) is by the microcontroller and peripheral integrated circuit with large front analog signal conditioning modules pipeline methane sensor. Unique real-time dynamic software application of temperature compensation technology enables sensor for sensing element is effective in compensating the drift, greatly improving the detection accuracy and long-term stability of the machine. Sensor to the methane concentration in coal mine gas drainage pipeline detection in a row, and to detect the methane density conversion into the corresponding frequency signal is sent to a device context. Suitable for coal mine gas drainage pipeline real-time continuous full range automatic detection of methane concentration.
