Ett mät- och reglersystem för temperaturkompensering
An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed. The solution presented in this thesis satisfies the goals that have been presented in the goal description. To achieve a more complete automatic calibration system there are some further improvements yet to be done.
