Have there been any users who have used digital valves and online oxygen analyzers in complex operating conditions?
Thread Content
As the title suggests, there is a current experimental project that is still in the planning stage; digital valves (digital control valves) are required for use with gas as the medium. I have never used them before, so I’m not very familiar with them. I asked some manufacturers, and they couldn’t do it either; most of them specialize in digital balance valves, and the medium used is water. So I was wondering if there are any experts who have encountered or dealt with similar situations; I would appreciate it if you could provide some guidance. Any contact information for manufacturers would also be helpful. Thank you very much. There are also online oxygen analyzers designed for use in complex operating conditions. I have consulted several manufacturers, and the minimum range for oxygen concentration is generally 0-5000 PPM. Is it possible to achieve lower concentrations? Please provide your contact information as well; thank you very much. Attach a digital valve from Baidu
What kind of digital proportional valve is it then? I’m not sure if this is feasible
It needs to be specified what to do: constant current or constant voltage, and the process details must be clear
