Gas Analyzer Working Principle
The emission analyzer has a core component called an absorption tank, which is highly polished to minimize light absorption and diffuse reflection. The absorption tank is an open space, and the gas continuously passes through the absorption tank.
The
stack emission monitoring system provided by Zetian is professional. Our company is also an expert on providing useful and cost-effective
environment-monitoring solutions.
Influence Factors on Emission Analyzer
With the increase of temperature, the gas density and the component to be measured in unit volume decreases, that is, the concentration decreases, which leads to the decrease of monitoring concentration.
With the increase of temperature, the volume of the absorption cell becomes larger due to thermal expansion and cold contraction. With the increase of gas medium thickness, the measured concentration will rise, and the overall measurement will decrease with the increase of temperature. Temperature also affects the voltage of the light source and the detection sensor, but generally, the influence is small. Therefore, the monitoring station should be equipped with air conditioning to keep the constant temperature to make sure the emission analyzer work normal.
There are booster fans near the place where the
emission analyzer is used, which can produce noise and vibration. Generally, the influence of this aspect will also be considered in the design of the
emission analyzer for sale. For the monitoring station building with large environmental noise and vibration, the influence of vibration on the
emission analyzer should be considered.
It may lead to a change of absorbance and pollutant concentration. It can effectively compensate for the optical path offset. However, if the vibration is large or the vibration deviates for a long time, the light path can not shine on the photoelectric sensor, then the displayed value will be on the range peak. At this time, it is necessary to disassemble the
emission analyzer and fix the light source again. Therefore, the environment and vibration will have an impact on the
emission analyzer.
