Abstract [en]

A theoretical investigation of existing sensor techniques, bothcommercial sensors and scientific studies, has been performed inorder to find a cost efficient fluid sensor with the ability todetect small amounts of non-conducting fluids. From these studies,six different techniques could be distinguished. The techniques weretested and compared, both in theory and practically, against certaincriteria’s such as temperature and movement sensibility. Three of thetechniques have been proved to work and two of them were built,installed and tested on an industrial robot manufactured by ABBRobotics.

The two most promising techniques distinguished were a photointerrupter and a Quartz Crystal Microbalance sensor. After tests itcould be concluded that both sensors fulfilled all preferences. However out of the two, the Quartz Crystal Microbalance sensorperformed best and could detect smaller amounts of fluid more quicklyand reliably than the photo interrupter.

This work has resulted in a patent application.
