Investigation of pressure balances using an optical method

Important results from the project

The project aimed to study a pressure balance using a new optical measurement technique (refractometer). The refractometer has a very high resolution, which means that we were able to study the effect of piston rotation, height of the piston, and the inclination of the instrument. Preliminary measurements and analysis have been carried out, which has provided more knowledage about both pressure waves and the optical method. Publication of results is planned to take place in a scientific journal.

Expected long term effects

The outcome of the project, in addition to increased knowledge in the area, will potentially lead to a more efficient handling of our instruments, which, to ensure continued high quality in our services. We have also, by carrying out the project, received new ideas on how we can carry even out better measurements which in turn can lead to additional publications in scientific journals beyond the one already planned.

Approach and implementation

The project has been carried out in reasonably well given the conditions. Covid-19 meant that the optical instrumentation could not be moved from Umeå to Borås, which caused the project to be delayed. In addition, this meant that the optical system could not be on site in Borås to the extent that was first planned. This led to the fact that measurements had to be made during a very short and intensive period. Despite this, relevant measurements have been carried out and an article is to be prepared for publication based on the data from the measurements
