Important results from the project
The goal of the project has been to develop new and improved equipment for calibrating surface temperature sensors. The equipment that was developed has an updated design compared to the previous one with three sensors, which allows the surface temperature to be extrapolated based on a physical model. Problems acquiring materials have meant that the equipment is not yet able to reach the high temperatures desired, but this will be addressed when possible.
Expected long term effects
The project resulted in equipment that can be used to calibrate surface temperature sensors with lower uncertainty than before, and in the future also at higher temperatures. The project has also, through internal presentations, given the entire group an increased knowledge of the difficulties with surface temperature measurements and how to best perform them. This in turn will lead to future calibrations being carried out in the best possible way.
Approach and implementation
First, existing equipment and those published from other labs were examined. Based on these and calculations and models, a new and improved equipment could be designed and manufactured. One problem was that the high temperature required a metal cylinder made of silver. It turned out to be difficult to find a supplier who could manufacture it or supply us with the material, which led to delays and an aluminium cylinder having to be used until it could be replaced at a later time.
