With more and more unexpected situations in the society, gas alarms have become an indispensable part of life. So what method can we use for gas alarms? The following is introduced by Beijing Tongde Venture Technology Co., Ltd.:
We should know the types of gas alarms prescribed by the national standards. Gas alarm can be divided into combustible gas leak detector, combustible gas alarm controller, combustible gas detector, household combustible gas alarm four series of products.
The leak detector is small in size and can be carried or held by hand. It is primarily used in gas leak detection and inspection. If there is leakage of gas, the leak detector will announce sound and light alarms, and the numbers will show the concentration of gas so that safety measures can be adopted in time to avoid the occurrence of serious accidents such as explosions.
Selection method:
1, clear detection of the use of selected instruments, portable detectors and stationary detectors 2, the selection of gas alarm categories In short, the detection of harmful gases has two purposes, the top is the explosion test, and the second is the drug detection. The so-called explosion test is to detect the gas content of risk places and over-alarm to prevent the occurrence of an explosion; the detection of the poison is to detect all the toxic gas content of the risk field and over-alarm to prevent the poisoning of workers. The scale of the explosion test is from 0 to 100% LEL, and the scale of detection is from 0 to several tens (or several hundred) ppm. There is a big difference between the two.
There are three kinds of hazardous gases in hazardous locations. The top spot, non-toxic (or low-toxicity) is flammable, the second is non-combustible, and the third is flammable and toxic. The first two conditions are easy to determine, the first test explosion, the second test poison, the third situation if there is exposure of personnel to detect drugs, if no one can reveal the explosion.
Explosive selection of flammable gas alarms, poison detection and selection of toxic gas alarms.
Leakage detection for long-term operation of production or storage positions uses fixed alarms; other portable instruments such as maintenance inspections, emergency detections, entry detections, and touring inspections are selected.
3. Clearly detect the target and select the best instrument type The instrument type includes the three main contents of the manufacturer, function target, and detection principle. When selecting the instrument type, consider the following principles:
1 The detection principle of the gas alarm should be used to the detection target and the requirements of the testing environment.
