Installation Specifications for Combustible Gas Alarms
Combustible gas alarms generally consist of a combustible gas controller and a combustible gas detector. Combustible gas detectors are required to be installed at gas leak sites or places where flammable or explosive gases exist. There are two types of detectors that must be installed. If the gas to be detected is lighter than air, the probe must be installed at a distance from the roof, and the probe should be pointed downward. If the gas to be detected is heavier than air, it must be installed at a distance from the ground, with the probe facing downwards. Precautions for installing combustible gas alarms
() The alarm should not be surrounded by strong electromagnetic fields (such as high-power motors and transformers) that would affect the operation of the instrument.
() The alarm is a safety instrument with sound and light display functions. It should be installed in a place that is easy for staff to see and hear, so that hidden dangers can be eliminated in time.
() The alarm should generally be installed at a height to facilitate routine maintenance by maintenance personnel.
() The alarm probe is mainly a detection element that contacts the combustion gas sensor. It is composed of a platinum wire coil coated with alumina and adhesive to form a sphere. Its outer surface is attached with rare metals such as platinum and palladium. Therefore, care must be taken during installation to avoid breaking the probe.
() The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the density of the gas to be measured is less than the density of air, the probe should be installed away from the roof with the direction downward. On the contrary, the probe should be installed away from the ground with the direction upward.
() The installation height of the open-air probe can be selected according to the density of the gas to be measured. Special attention should be paid to the fact that the probe should be installed on the leeward side.
() The connecting cable of the alarm circuit should be protected by a protective sleeve. It is best to add a metal hose at the connection point of the probe, and be sure to be consistent with the explosion-proof level of the factory.
() After installation and debugging, be sure to install a breathable and waterproof cover to prevent rainwater from entering and damaging the probe
