Toxicgas detectorIt should be installed within 1m of the air source that may leak. Flammable in small explosion-proof areasgas detectorIt must also be installed within 1 meter of a possible leak source. Flammable gas probes with a specific gravity greater than 0.975, that is, heavier than air, such as liquefied gas, should be installed within 0.3-1m from the ground;flammable gas probe, such as hydrogen, should be installed within 0.3-2m from the ceiling.
2. Explosion-proofCombustible gas detectorDetection range: A detector that responds to changes in the concentration of single or multiple flammable gases. It can be divided into point, linear and gas detector installation spacing. A detector is installed every 15 meters outdoors, that is, the protection radius is 7.5 meters, and a detector is installed every 7 meters in indoor closed and semi-closed places, that is, the protection radius is 3.5 meters.
The intrinsically safe probe has no special requirements for the tightness of the wiring pipe, and the flameproof probe needs to take sealing and explosion-proof measures that meet the requirements of the wiring pipe specification, such as the use of explosion-proof junction boxes, explosion-proof connectors, elbows, etc
3、Combustible gas detectorThe installation distance is 15m outdoors, that is, the protection radius is 7.5m, and the installation distance of indoor closed and semi-closed places is 7m, that is, the protection radius is 3.5m.toxic gas detectorIt should be installed within 1 meter of a possible leak source. Combustible gas detectors in small explosion-proof areas must also be installed within 1 meter of a possible leak source. Flammable gas probes with a specific gravity greater than 0.975, i.e. heavier than air, such as liquefied gas, should be installed within 0.3-1m of the ground; flammable gas probes with a specific gravity less than air, such as hydrogen, should be installed within 0.3-2m of the ceiling.
