ET 500 Two-Stage Piston Compressor Unit Show data sheet (pdf file) Print page
Technical Description
The unit provides all necessary data for recording the compressor characteristic and to depict the compression process on a p-V diagram. The pressures and temperatures for both stages are recorded using electronic sensors and indicated on digital displays. The air throughput and the electrical power consumption are also measured. The measured data is transmitted to a PC using a data acquisition card, and further processed on the PC. The unit is equipped with safety devices such as pressure relief valves and pressure switches.  
Learning Objectives / Experiments
