The multi gas detector is a tool used for high-intensity gas leak detection. It exists in various factories. This kind of instrument is also divided into many kinds, which is very different from the gas analyzer. So, next, Yuante Technology will take you to understand this instrument!
The difference between gas analyzer and gas detector:
1. The accuracy of the data
The gas detector can only provide qualitative analysis results and relatively rough quantitative analysis data. The data displayed by the instrument cannot withstand refinement and cannot be used for error analysis (because the "error" can only be talked about when the analysis data deviates very little from the true value). Therefore, it is impossible to decide (decide) important process improvement and adjustment measures as accurate analysis data.
The gas analyzer is a strict measuring instrument that can provide very accurate data C during quantitative analysis, which can be used as a basis for improving and improving coal production and safe production. Use it to guide and implement production management, quality management and enterprise management. Even this kind of data can also be used as an important basis for judicial and criminal investigations, used to initiate litigation and determine the boundary between right and wrong.
2. Different detection methods
The gas detection alarm uses the probe to be directly exposed to the measured air or sample gas environment for detection. The gas analyzer introduces the measured gas (sample gas) into the instrument in a special way for measurement, and then causes the outside of the instrument to be emptied.
3. In the detection process, methods to eliminate interference factors
The gas detection alarm directly places the sensor in the atmosphere of the large environment. In the structure design of the instrument and the actual use and detection process, the structural design of the instrument and the interference factors to the measurement in the ambient atmosphere are not considered, and various interference factors are not eliminated. Design capabilities.
In the design, selection and use of gas analyzers, various internal and external factors that affect the determination of gas analyzers must be fully considered, and they must be carefully eliminated one by one, so as to ensure the accuracy and authenticity of the test data. Otherwise, The influencing factors will be ignored, which is not allowed and unacceptable.
4. How to complete the entire determination process
When the gas detection alarm, just place the instrument in the atmosphere being tested, the instrument can display its value. The gas analyzer must carefully introduce the sample gas into the instrument, and then strictly adjust the process and technical conditions, such as temperature, excitation, flow, etc., until the operator adjusts the instrument until a stable chemical process is achieved. To obtain accurate measurement data. The data obtained before this is incorrect and must be discarded.
5. Control method of measurement conditions
The gas detection alarm is not equipped with the adjustment and control part of the technical conditions of the sample gas, and the environmental conditions of the sample gas are not considered, and the detection is carried out directly.
A complete set of 4 gas path systems and external supporting equipment provided in the gas analyzer constitute a complete chemical process flow. The gas analyzer internally adjusts and controls the working conditions of the sample gas to achieve the normal and stable operation of the sensor. The purpose of this is to ensure that the gas analyzer can obtain accurate measurement data.
6. Instrument structure
The gas detector has a relatively simple structure, including only the probe (sensor) and the sensor signal conversion circuit. The gas analyzer is not only equipped with probes (sensors) inside, but also has a complete set of gas path system, that is to introduce the sample gas into the instrument, and then lead out a complete set of 4 gas path system for venting or recovery of the instrument.
