Remarks on Ansaldo measurements
• The oil has reached a max temperature of 242º C. This is about 12 º C higher than the normal value.
• It is possible to re-scale the temperature seen by the coil to a “normal” oil temperature thanks to the correlation between oil temperatures and max temperatures measured during the cycles
![Page 11: Temperature measurements during curing of inner layers at the 3 CMAs](https://reader035.fdocuments.us/reader035/viewer/2022070419/56815a74550346895dc7db1a/html5/thumbnails/11.jpg)

Therefore….We can consider that the max coil temperature
for a max oil temperature of 230° C would be about 7.5 ° C less, it means a max temperature of 222 ° - 223 ° C
![Page 13: Temperature measurements during curing of inner layers at the 3 CMAs](https://reader035.fdocuments.us/reader035/viewer/2022070419/56815a74550346895dc7db1a/html5/thumbnails/13.jpg)
From Ansaldo dummy• If we estimate the error between coil and sensor in
the mould starting from the Ansaldo dummy and we apply such error to the Ansaldo’ s mould measurements during the tests we get:
Measured by sensor coil

N.B. the error increase with temperature therefore we are probably underestimating it
