Як далеко може ваш газ детектор виявлення юрисдикція?
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.
What are the environmental conditions for installing a gas detector?
Відповідь: Газ детектори мати їх власні адаптивні робочі умови, і ми головне потреба до звертати увагу до ці базові умови, такі as вологість, температура і тиск. Generally, it is suitable to install them in our environmental factory, and they can basally be directly installed and fixed. однак, when we install them in confined spaces, such as pipes and flues, we we should pay attention to the working умови. Most of our gas detectors, no matter what brand, can adapt to the conditions. -20} to 50 degrees, вологість нижче 90 відсоток , no конденсація, and тиск 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 presolution equipment. To carry out gas лікування і лет те газ те те, що відповідає умови enter the газ датчик голова.
Is there any effect of excessive dust at the installation location?
Відповідь: Too much dust in the gas will easily lead to the адсорбція of the газ чутливі компоненти of the gas sensor, which will lead to blockage and зменшення the виявлення точність. Тому, одноразово використано в a високо пил навколишнє середовище, пил повинен бути фільтрованим і очищеним регулярно відповідно до пилу ситуації. тут, будь ласка пам'ятайте не до прання з водою, або серветка з спиртом та іншим рішеннями. тільки чистий сенсор поверхня з a чиста м'яка тканина.
