Displacement measurements during RHT
→
Europe/Zurich
§ According to EN-MME, DIC is the best way to go. We could think on a first test by the end of the month.
· Further investigating LVDT or capacitive sensors for the use on real coils is not a bad idea from their point of view. But it is not worth it now to add this complexity to the first mock-ups. We could also characterize LVDT and capacitive sensors later on.
§ The most important comments from the meeting are:
· It took a bit of time to come back to us because they wanted to really analyze the case and come with a consolidated proposal
· They are aware of our different mock-ups and the order on which we will proceed.
· From their point of view, there are 3 types of solutions:
o High temperature LVDT: Tricky to ensure the correct stability and support, tricky cabling and need of "sophisticated" feedthroughs. Measurement is unidirectional, we would need to install various sensors.
o Capacitive sensors: Very similar tricky points to LVDT, but here the key point is the parallelism of the faces where you measure. They are aware of the solution Jose Luis sent to us (large diameter sensors).
o Digital image correlation (DIC): For them, the most suitable option. This is the way they want to go for the immediate future.
· The tests can be done in:
o Electro heat oven @air atmosphere:
§ They need the manufacturer to intervene in the oven (to keep warranty) to make it compatible with measurements.
§ It has great added value for them, they will ask for the intervention. It will be ready most likely Q3 2025.
§ This will allow 3D and 2D DIC measurements
o TAV oven:
§ Vacuum or Argon atmosphere
§ It has already one window from the main door. We can do straight away 2D DIC measurements – End of April.
§ There is a small issue on the size of the setup. To be confirmed, but in principle, they can only accommodate 650 mm.
There are minutes attached to this event.
