Questions to manufacturers of online carbon dioxide analyzers
Thread Content
I would like to ask everyone: what are some good manufacturers of online carbon dioxide analyzers? Both domestically and internationally, it’s fine
Basically, all manufacturers of analytical instruments can produce CO2; it’s not difficult at all, including domestic manufacturers. Only trace amounts will cause a slight problem.
ABB – it’s a reliable choice, but the price is quite high, 11! ! ! ! ! ! ! ! ! ! ! ! !
I have used both ABB and Siemens products, and the performance of both has been good. The key to the analysis system is to implement an appropriate sample gas preprocessing system tailored to different process conditions.
It is best to provide a list of gas components, as some gases can cause cross-interference; the configuration of the instrument should be determined based on the level of difficulty associated with the application. Also, the range is unclear; the range determines the length of the gas chamber. If the requirements for routine control in measurement are not high, it is recommended to use domestically produced products; in addition, strict quality control should be applied during preprocessing.
Thank you. . . It is required to detect levels below 50PPM; the main component is natural gas. Do ABB and Siemens have any models suitable for this purpose? Online detection is required, not portable versions
Let me list some; such systems are mainly available abroad, hehe: ABB modular, Siemens positive pressure purging, Emerson explosion-proof, Servomex multi-band, Fuji – inexpensive... Teledyne offers high measurement accuracy
If the background components do not contain CO, then there are no issues with measurements taken by Siemens or ABB, and this represents a normal application scenario. Siemens uses the U6 model, while I can’t remember the model number for ABB; previously I used ABB devices whose model names started with the letter EL. If there is CO, the configuration may need to be even higher. If it is Zone 0, Siemens’ U6F can be used for positive pressure purging; ABB’s models are likely to be explosion-proof. The background component is natural gas, and the output pressure should be in the range of several dozen kilograms; the main tasks in pre-treatment include providing electric heating and removing water.
