Combustible gas detector locations should choose the valve and pipe outlet interface, or easy to discharge a radius of 1 meters range near the site, as close as possible, but do not affect other equipment operation, and try to avoid high temperature and high humidity environment.
When the gas detector is used for large area gas detection, 10~12 square meters of a probe can be used and the effect of detection and alarm can be achieved.
The installation of flammable gas detectors can be installed by roof lifting, wall installation or pipe holding. The installation must be reliable and reliable. Meanwhile, it should be considered for easy maintenance and calibration.
The installation height of flammable gas detector: when detecting hydrogen, natural gas, city gas and other gases less than air, it will install 1 meters away from the roof. When detecting liquefied petroleum gas and other gases larger than air, it will install 1.5 to 2 meters away from the ground.
A three core shielded cable should be used for the wiring of a combustible gas detector, with a single line diameter of more than 1 square millimeters, and the shielding layer must be grounded when the wiring is connected.
Combustible gas detector field wire wear pipe, the pipe should meet the requirements of fire fighting, the pipe should be connected with the probe, in order to achieve the requirements of fire fighting.
When a combustible gas detector is installed, the sensor should be fixed at the bottom.
The combustible gas detector should be connected under the power failure condition, and it is sure that the electricity will be energized after the connection is correct. We should open the cover and debug the probe (for the flameproof probe SP-1102) when we confirm the scene of no gas leakage.
The combustible gas detector should be calibrated at least once a year to ensure the accuracy of the detection.
