The trainer comprises original components as used in heating and sanitation systems and is therefore relevant in practice.
There are six expansion sections. One of the sections is fitted with a compensator. The elongation of the pipes is indicated on dial gauges. A force measuring device enables the expansion force to be determined.
Learning Objectives / Experiments
