Comment loin peut votre gaz détecteur détecter la juridiction?
A: Users often ask this question and mistakenly think that the gas detector can detect a long distance. In fact, there is a misunderstanding here. Gas detectors, especially fixed gas detectors, are generally diffused, that is to say, gas needs to diffuse to the sensor head of gas detection before they can detect the concentration. Otherwise, even if the toxic gas is nearby, it will not be detected. To give a simple example: human sense of smell is a very sensitive organ, which can ask about trace gases in the air up to ppb level or above, so sometimes we need to get close to ask, and sometimes we can smell them far away, which is due to the direction of air flow and the concentration ratio. The gas is dissolved in the atmospheric air, which may not be detected by the gas detection equipment nearby because of the wind direction. As the gas flows away from the gas leakage point, the gas concentration is lower, so the gas concentration detected in the distance is safe, which does not mean that all locations are safe and the concentration is so low. There is no strict standard for how far to install one nearby. Only in combination with the site situation, the location distribution of hazard sources is reasonably arranged. It is recommended to install one equipment in a large area of 20m2, or one equipment in a range of 10-20 meters.
Qu sont les conditions environnementales pour installation a gaz détecteur?
Answer: Gas detectors have thers own adaptive working conditions, and we principalement need to pay attention to these basic conditions, such as humidity, temperature and pressure. Généralement, it is suit to install them in our environmental factory, and they can fondamentalement be directement installed and fixed. Cependant, quand we install them in confined spaces, such as pipes and flues, we should pay attention to the working conditions. Most of our gas detectors, no matter what brand, can adapt to the conditions. -20 to 50 degrees, humidity below 90 percent , no condensation, and pressure within 100kp. Once the environmental conditions are not in it, it will affect the accuracy of measurement and the service life of the instrument. At this time, we should consider adding gas pretreatment equipment. To carry out gas traitement et laxe le gaz qui remplisse les conditions entre le gaz capteur tête.
Is there any effect of excessive dust at the installation location?
Réponse: trop beaucoup poussière dans le gaz conduira facilement à l’adsorption de le gaz sensible composants de le gaz capteur, qui conduira à bloquer et diminuer la détection précision. Par conséquent, once utilisé dans a haut poussière environnement, poussière doit être filtré et nettoyé régulièrement accordant à la poussière situation. Ici, s’il vous plaît souvenez-vous pas à lavage avec eau, ou essuyez avec alcool et autres solutions. Seulement nettoyez le capteur surface avec un propre doux chiffon.
