How far can your gas detector detect?
How far can your gas detector detect? Users often ask this question, mistakenly thinking that gas detectors can detect long distances. In fact, there is a misunderstanding here. Gas detectors, especially fixed gas detectors, are generally diffuse, which means that gas Diffusion is required onto the gas detection sensor heads for them to detect the concentration. Otherwise, even if the toxic gas is nearby, it will not be detected. To give a simple example: the human sense of smell is a very sensitive organ and can detect trace gases in the air ranging from trace amounts to ppb levels. Sometimes we need to get very close to detect them, and sometimes we can smell them from far away. To, this is due to the direction of air flow and concentration ratio. Gases dissolved in atmospheric air may not be detected by nearby gas detection equipment due to the wind direction. As the gas flows farther away from the gas leak point, the gas concentration becomes lower, so the gas concentration is detected at a distance. Safety does not mean that all locations are safe and the concentration is so low. There is no strict standard for installing one at the nearest distance. Only the location of hazard sources can be reasonably distributed based on the on-site conditions. It is recommended to install one in a range of 20m2, or to install one device in a range of 10-20 meters.
What are the environmental conditions for installing a gas detector?
Gas detectors all have their own working conditions to which they are adapted. We mainly need to pay attention to the basic conditions of humidity, temperature and pressure. Generally, they are more suitable for installation in our environmental factories. Basically, they can be installed and fixed directly, but we install them to In confined spaces, such as pipes and flues, in these special environments, we must pay attention to understand the working conditions. Most of our gas detectors, no matter what brand, they can adapt to the condition of normal temperature; -20 to 50 degrees, humidity below 90% without condensation, pressure within 100kp. Once the environmental conditions are not here, it will affect the accuracy of the measurement and the service life of the instrument. At this time we must consider adding gas pretreatment equipment. To perform gas processing, let the gas that meets the conditions enter the gas sensor head.
Will there be any impact if the installation location is too dusty?
If the dust in the gas is too large, it will easily cause the gas sensor of the gas sensor to be adsorbed and blocked, and the detection accuracy will decrease. Therefore, once used in a high dust environment, the dust must be filtered and the dust must be cleaned regularly depending on the dust condition. Remember not to wash it with water or wipe it with alcohol or other solutions. Only use a clean, soft cloth to clean the sensor surface.
