& nbsp; As we all know, gas detection is very necessary for safety protection, especially in many production and processing industries and families, where combustible gases are widely used. And as long as there are flammable and explosive gas places, need to use combustible gas detector, it can effectively protect the limited space gas detection, to ensure the safety of the space. In order to ensure the use, we need to pay attention to the relevant installation matters when installing the portable combustible gas detector. So Portable Combustible Gas Detector What are the installation precautions? The following is a brief introduction by yi yun Tian:

portable combustible gas detector installation precautions:

1, should be in the case of power failure wiring.

2. the installation position should be as close as possible within a radius of 1 meter from the valve, pipeline interface, air outlet or place prone to leakage, but do not affect the operation of other equipment.

3. when used for large-area gas detection, a probe can be arranged with 20-50 square meters, which can achieve the effect of safety monitoring.

4. installation height: when detecting gases lighter than air such as hydrogen, natural gas and city gas, the installation shall be about 1 meter above the roof. When detecting gases heavier than air, it shall be installed about 1.5~2 meters below the ground.

5. The installation method can be roof hoisting, wall hanging or connecting pipes, etc., and the installation should be firm and reliable.

6. The on-site wiring should be threaded through the pipe, the pipe used should meet the requirements, and the pipe should be connected with the probe to meet the requirements.

7. The sensor should be fixed downward during installation.

8. The installation position of the portable combustible gas detector needs to be close to the suspected leakage point of combustible gas or the position to be detected.

9. when the specific gravity of combustible gas is detected to be less than air, the installation position of combustible gas detector should be above the suspected leakage point and not more than 30cm from the ceiling. when the specific gravity of combustible gas is detected to be greater than air, the installation position of portable combustible gas detector should be below the suspected leakage point, distance from the ground is not more than 30cm.

10. some portable combustible gas detectors are not strong in anti-electromagnetic interference, so when installing such portable combustible gas detectors, keep away from electromagnetic interference sources.

In summary, it is the installation precautions of the portable combustible gas detector. It is worth noting that if the detected environment lacks good ventilation conditions, when combustible gas leaks, it is easy to appear that the combustible gas content in the air in a certain part is close to or reaches the lower explosive limit concentration value. Moreover, according to the analysis results of on-site accidents, many of them are caused by incorrect or irregular installation of portable combustible gas detectors. Therefore, when installing the portable combustible gas detector, we should pay attention to the installation position as much as possible to ensure the safety of the detection.
