DESCRIPTION
Technical Description
This experimental unit allows variables that affect the process (such as capacity, dead space, flow rate and state of the intake air) to be adjusted from the panel.
The simulator can model operating states up to the theoretical limits. The significance of the dead space and air re-expansion thus becomes clear.
The measured values are transmitted directly to a PC via USB. The data acquisition software is included.
Learning Objectives / Experiments
