In the system control of the new dry cement production line, the gaseous composition of the chambers, the decomposition furnaces and the first cylinders (O2, NO, CO, CO2) are very important. For example, if concentrations of oxygen, carbon monoxide, nitrogen oxides are known, the ventilation and incineration in the kiln can be accurately determined and adjusted in a timely manner. However, in a number of field studies, experts on the Network found that most of the online smoke analyzers in cement enterprises, especially the most important smoke room analyzers, are now damaged or not equipped even after they have been damaged. This is due to the poor working environment of the smoke room, where the smoke analyzer ' s probe is permanently located, making it difficult to guarantee outstanding operational conditions. And the on-line flue gas analyzer's protection is messy and requires a service provider.

The equipment currently prevalent is the Infrared Sensor Multifunctional Fneo gas analyzer, which should allow elements to absorb a particular wavelength, with different levels of infrared light being absorbed when detected gases enter the Infrared Absorption Pool, thus calculating the gas content. Infrared sensory properties are resistant to moderate toxicity, wide range of scale and agility. The sensors are not the same for different working methods equipment, and the electrochemical sensors are smaller in size and can be transposed to a handheld type, although the error of the sensors is around ±5°, which is consistent with the norm, but relatively poor. Electrochemical sensors are also vulnerable to interference with other gases, increasing errors in the measurement results. So electrochemical flue gas analyzers are relatively cheap, and if they have a lower budget, they can choose them.

Multifunctional flue gas analyzers are capable of operating in many large and medium-sized chemical industries, and how to improve efficiency, reduce energy consumption and reduce energy-saving emissions is the direction of development. In many former steel metallurgy, petrochemicals and power plants, flue gas analyzers have been installed and have been reported to have significantly improved the efficiency of the consumption process. The multifunctional flue gas analyzer should be primarily able to be present in chemical consumer sites to analyse the composition of the smoke generated in consumption in order to adjust direction at any time. There are two main ways of working with the multifunctional flue gas analyzer: the electrochemical sensor and the infrared sensor. The control of the shut-out efficiency is less than detection of two gases: oxygen content and carbon monoxide, multi-purpose flue gas analyzer, which is used to extract gas from the kiln and automatically stop the composition analysis.

Characteristics of the sulfur dioxide analyzer: Multiple signal output selection: simulator 4-20mA, 0-5V; digital signal: RS485; frequency signal (frequency scale adjustable). High accuracy: The selection of the world-renowned sensor brand, the ~30+50°C temperature compensation, multi-level linear proofreading ensures high accuracy of the instrument. Infrared remote control operation of the sulfur dioxide analyzer: allows you to complete the transporter ' s self-assembly on site, such as checking, setting, calibrating, alarm point setting. The other products together have the key operation function. sulfur dioxide analyzer circuits and blast-proof shell planning: the circuits are planned in full accordance with the requirements of this prop, and the shell corresponds to the national blast-proof requirements. Device protection is convenient: by plugging in a world regulated smart sensors, on-site protection is very convenient. Multi-level alert: two levels in the field

The sulfur dioxide analyzer can be divided by structure into: handheld sulfur dioxide analyzer, fixed sulfur dioxide analyzer, sulfur dioxide transformer (also known as sulfur dioxide probe), sulfur dioxide online profiler, sulfur dioxide alarm, portable sulfur dioxide analyzer, with details of the link-check pictures that can access the reference. The product usually has a regulated signal output. There are two types of products that are visible and not visible. The purpose of the equipment is to transmit to the upper plane the measured signals of sulfur dioxide gas concentrations detected on the ground or converted to 4-20mA current signals, 0-5V voltage, RS485 frequencies, etc. Product characteristics and parameters are as follows: Overview: AP-G-SO2-2 fixed sulfur dioxide analyzer. It's the conversion of the sulfur dioxide gas concentration to a 4-20mA current signal that was detected on site.

Accuracy of the light-dialysis portable gas detector: the verification method, the error profile, in the application of the profile instrument, and the data for each test result, need to be analysed by error to determine the authenticity, reliability and reliability of the data profile. A qualified profiling operator would not, and should not, report or publish the results of each autopsy. This data (or group) is usually reported or published as correctly measured when the sum of the errors in the analysis data is determined after the result has been measured and the sum of the errors in the analysis is less than the agreed error in the rule. Otherwise, inaccurate data can give the producers severe negative consequences. Common instrument calibration of portable gas detectors as a quantitative profiler is necessary before a quantitative profile can be performed
