Code for installation of combustible gas detection probes
A.Flammable gas detection probe selection should be selected valve, pipe interface, outlet or easy to leak near the radius of 1 meter range, as close as possible, but do not affect other equipment operation, while avoiding high temperature, high humidity environment.
B.Combustible gas detection probe for large area gas detection can be used when 10 to 12 square meters a probe layout, but also to detect the alarm effect.
C.Combustible gas detection probe installation can be used roof roofing, wall installation or pipe installation, should ensure that the installation of solid and reliable, should be considered easy to maintain, calibration.
D.Combustible gas detection probe installation height: detection of hydrogen, natural gas, city gas and other specific gravity is less than the air gas, the use of about 1 meter from the roof to install; detection of liquefied petroleum gas and other specific gravity is greater than the air, the use of 1.5 to 2 meters from the ground installation.
E.Combustible gas detection probe wiring should be used three-core shielded cable, a single wire diameter greater than 1 square millimeter, wiring shield must be grounded.
F.Combustible gas detection probe on-site alignment should wear pipe, the pipe should be used to meet the fire requirements, the pipe should be connected with the probe to meet the fire requirements.
G.Flammable gas detection probe should be installed when the sensor down fixed.
