Flexible gas system

One thing that is different with this rig compared to a commercial fatigue testing machine is the introduction of a gas system. We want a flexible system so we can perform testing in many different environments. After some research, we decided to go for a system from Bronkhorst, supplied by Omniprocess. This system includes flow meters for gases and liquids and a controlled evaporation module (CEM), which adds moisture to the gas. We added a double-ended cylinder from Swagelok as liquid reservoir. With this setup, we can reach moisture contents well above 80%, which would have been difficult if we had gone for a water bath system. Besides, our system also allows us to use other liquids than water.
