At present, in the application of industrial fields, combustible gas detector is one of the indispensable safety equipment. The working principle of combustible gas detector is generally by detecting whether the concentration of combustible gas in the air reaches a certain threat value, when the combustible gas in the air reaches a certain concentration, the combustible gas detector will automatically sound and light alarm to remind people to take corresponding measures in time to avoid the occurrence of major accidents, so as to ensure the safe life of enterprises and the safety of people's lives. So do you know Combustible Gas Detector what you should pay attention to when detecting combustible gas? The following is an introduction by Yi Yuntian:

Combustible gas detector should pay attention to the following aspects when detecting combustible gas:

1. find out the leakage points of the device

first find out what the leakage points of the device are, analysis of their leakage direction, pressure and other factors, while drawing the location of the probe distribution map, according to the severity of the leak is divided into Ⅰ, Ⅱ, Ⅲ three levels. At the same time, according to the density of the leakage gas, combined with the air flow trend, the three-dimensional flow trend chart of the leakage is integrated, and the initial point setting scheme is made at the downstream position of its flow.Then, according to the specific factors such as the wind direction and airflow direction of the place, the leakage direction of combustible gas is judged if a large amount of leakage occurs.

2. electromagnetic interference should be avoided when using combustible gas detector

electromagnetic environment affects combustible gas detector there are three main paths: 1 is the workplace electromagnetic interference. The 2 is a narrow pulse group on the power supply and other input and output lines in a fixed gas detector. 3 is the static electricity generated by the human body.

3. Use explosion-proof combustible gas detector

because there may be explosions in many places, therefore, we should choose the explosion-proof combustible gas detector when choosing the combustible gas detector. The explosion-proof grade shall not be lower than the corresponding grade in the current specification.

4. Avoid damage to the probe

During the installation of the combustible gas detector, be careful not to burn other sensors contact the alarm probe damage, because the probe is the alarm in the more critical original, once damaged, for the alarm, it may be more serious damage, affecting the alarm alarm correctly.

In summary, the combustible gas detector should pay attention to some aspects when detecting combustible gas. Of course, in order to ensure the normal use of the combustible gas detector, its installation is also a very important aspect.Therefore, we need to fix each combustible gas detector at the installation point with the fixed bracket provided by the manufacturer according to the instructions of Yiyuntian manufacturer. At the same time, we need to connect the power line and signal line of the combustible gas detector according to the instructions. In this step of wiring, we must strictly follow the instructions of the manufacturer. Otherwise, if the connection is wrong, the combustible gas detector will be damaged during the power-on test.
