Methane sensor GJC4 (gas sensor)

Methane sensor GJC4 (gas sensor) GJC4 (GJ4) methane sensor to monitor changes in the concentration of methane in the mine and the development of special instruments. The sensor can automatically mine methane concentrations in the environment into a standard electrical signal transmission to the associated equipment, with local display of methane concentration, overrun sound and light alarm and power-off function. Output frequency 200 ~ 1000HZ, corresponding to 0 ~ 4% CH4 thermal conductivity components work:: Technical parameters: Measuring range: 0 ~ 100% CH4 Display: four red LED display Output: catalytic element work output frequency 1200 ~ 2000HZ, corresponding to 0 ~ 100% CH4 Alarm: two intermittent sound and light alarm pole Operating voltage: 9 ~ 18V DC Working current: ≤70mA (18V DC) sensor uses a single core cross-sectional area cable should be no greater than 1.5m㎡ sensor associated equipment transmission distance should not be less than 2000m proof type: Exib I Jining Machinery Co., Ltd.
