Bearing in mind the adversities at the first attempt and the possible influence of the human factor, we have (hopefully) solved it better this time with expert support. Of course, there will be a detailed and transparent report on the exact development of the idea, the first prototypes and many empirical values, but today I don’t want to withhold a short progress report from you, because the project is alive, even if many things are unfortunately taking longer than expected. Unfortunately, this is also due to the supply chains and the need for precise sensor technology. You would think that you could get something like this within a week, but apart from hardware store goods, the tide is completely out. So at first we had to wait. But on Friday, the miracle finally happened and the long-awaited sensors (part of which can be seen in the picture below) are now (almost) complete.
For the fan control and final recording of the data supplied by the calibrated multifunctional transducer and transmitter, we also have a well-known partner on board who wants to realize the automation part for us. Here too, I would like to thank the industry for helping us to implement such an individually optimized solution. As far as the human factor is concerned, which I just mentioned, a special mounting or fastening system as well as operating instructions and checklists will ensure that all the fans to be measured are in the same place, regardless of their strength, and that the measurement process is also controlled. The planning engineer has really outdone himself here, but there is no other way if you want to measure cleanly and transparently.
As you can see, we will no longer be measuring with an impeller anemometer, although the initial results didn’t look too bad. We are using highly sensitive hot-wire probes for a large working range and, of course, the differential pressure sensors of the multifunctional transmitter. We will of course publish further details in due course, as everything has to be reprinted first. You can see how long just one of the parts will take in the picture below and yes, unfortunately a few more kilos of filament are needed 😀
For reasons of transparency, we will also disclose the complete construction later, so that there will be no secrets and anyone who has a genuine and justified interest can get help from us to rebuild it. In other words, a kind of open source for printing and sensor technology. However, the details for the software still need to be clarified, which is no longer in our hands. But that’s the third step, now it’s time for finalization and the test phase. Yes, it all takes a little longer, but if you’re already investing so much time and resources, it has to have a solid foundation. I’m certainly not going to fall for flowery words again, now actions and facts have to speak for themselves.
