Hydrogen, the 1 highly flammable and explosive gas, has been considered to be the 1 potentially dangerous gas, so hydrogen detectors are needed to monitor hydrogen leaks in many industrial areas to ensure workplace safety. However, the installation height of the hydrogen detector will directly affect its monitoring effect and service life to a certain extent. Therefore, it is necessary to follow certain installation specifications. Do you know how high the hydrogen detector is? The following is an introduction by yi yuntian:

Article 4.1.2 stipulates that when the ratio of the molecular weight of the leaking gas medium to the molecular weight of the ambient air is less than or equal to 0.8, the leaked gas is lighter than air.

Article 6.1.2 stipulates that when detecting flammable or toxic gases lighter than air, the installation height of the detector should be within 2 meters above the emission source.

Article 6.1.1 stipulates that the gas detector shall be installed in a place free of impact, vibration, strong electromagnetic interference and easy maintenance. The net air between the installation place of the detector and the surrounding process pipelines or equipment shall not be less than 0.5 meters.

#4,. Article 2.3 stipulates that when the release source lighter than the air is in a closed or partially ventilated semi-open plant, in addition to setting up a detector above the release source, a gas detector should be set up at the highest point in the plant where gas is easy to accumulate.

In summary, we can see that the installation height of the hydrogen detector should be determined according to the density of hydrogen. In general, because hydrogen is lighter than air, the density of hydrogen is 0.0899g/L, so the installation height of the hydrogen detector should be within the height range of about 30cm to 60cm from the ground. In addition, in order to ensure the long-term stability of the hydrogen detector, the installation environment should be dry, ventilated and suitable for temperature. At the same time, it should be avoided to install in the area of corrosive gas or chemical substances, so as not to affect the service life of the hydrogen detector.
