The portable analyzer can be used between multiple furnaces and is suitable for daily calibration, diagnosis and debugging, and a single analyzer can cover the entire workshop; the fixed (online) analyzer is installed on a single furnace or generator for continuous measurement, and is suitable for online CO correction, continuous monitoring and alarming of key furnaces. The reasonable configuration of most workshops is: the key furnace or generator is fixed, and the entire workshop is equipped with a portable one for daily calibration and problem diagnosis.
- Portable: one multi-purpose device, suitable for daily checksum diagnosis
- Fixed type: continuous monitoring, suitable for key furnace and generator outlets
- Portable is low cost but relies on personnel; fixed continuous but requires investment for each furnace
- Recommended combination: fixed at key points + portable in workshop
- Both require calibration and sampling system maintenance
Contrast
| Dimensions | Portable | Stationary (online) |
|---|---|---|
| Install | Ready to use | fixed to stove or generator |
| data | Spot measurement, data within the measurement period | Continuous, accessible to control systems and data platforms |
| cover | One covers multiple furnaces | One unit corresponds to one measuring point |
| Typical uses | Daily verification, diagnosis, debugging, audit demonstration | Online CO correction, continuous monitoring, alarm |
| Personnel dependence | Requires personnel operation | run automatically |
| invest | Single unit investment, large coverage | One set for each measuring point |
When to choose portable
- There are many furnaces in the workshop and the carbon potential needs to be checked in turn every day;
- It is necessary to troubleshoot the atmosphere problem of a certain furnace;
- New furnace debugging and generator acceptance;
- The budget is limited, so first solve the problem of "can be verified".
When to choose fixed
- Critical furnaces produce high-value or safety parts that require continuous demonstration of controlled atmosphere;
- The CO in the nitrogen-methanol atmosphere fluctuates greatly, and the carbon potential calculation needs to be corrected in real time;
- The outlet of the generator with centralized gas supply needs to continuously monitor the gas quality;
- It is hoped that the atmosphere data can be connected to the monitoring platform to realize automatic alarm.
Recommended combination
| Workshop size | Recommended configuration |
|---|---|
| 1–3 stoves | A portable three-gas analyzer |
| 4–15 furnaces | Portable + generator outlet or key furnace fixed |
| More than 15 units, centralized air supply | Generator outlet fixed + key furnace fixed + portable |
Gauss Control Product Center also provides FAA-B portable three-gas analyzers, fixed analyzers and CCA-20 carbon analyzers under the analyzer category, which can be combined according to the above ideas.
Questions to ask when selecting
- What components need to be measured (CO, CO₂, CH₄, O₂, H₂)?
- Can the measurement range and accuracy cover the process?
- Is there built-in carbon potential and PF calculation?
- Can the data be exported or connected to the Internet?
- Is calibration convenient? Are calibration services and reports provided?
- Is the sampling system suitable for the site (dust and condensation proof)?
Frequently asked questions
The portable analyzer measures so many furnaces every day, how to manage the data?
Prioritize the model that can store and export measurement records. Enter the furnace number and time during measurement, and associate it with the carbon potential calibration record.
Will a broken fixed analyzer affect production?
If it is only used for monitoring, a portable temporary replacement can be used in case of failure; if it is used for online correction of carbon potential, a fallback strategy should be designed in case of failure (such as restoring the use of set CO).
Can one fixed analyzer be used to measure multiple furnaces in turn?
It can be achieved through multi-channel switching sampling, but the update cycle of each measuring point will become longer, and it needs to be evaluated whether it meets the requirements.
