TEPGC Peralatan Proses Ekspansi Gas Ideal, Dikendalikan dari Komputer (PC)

The "TEPGC" is a unit designed to demonstrate the expansion and compression processes of a perfect gas and the basic principles of thermodynamics.

The unit consists of two rigid vessels connected to each other. They are made of methacrylate to facilitate the visualization of the experiments and to thermally isolate their content from the external conditions. One of them works under pressure and the other under vacuum conditions.

There is a computer controlled air pump between both vessels. It includes pipes and valves that will be activated to select the different experiments. One of the objectives of the pump will be to pressurize the pressurized vessel with air and remove the air from the vacuum vessel.

A pressure sensor, a temperature sensor and a gauged overpressure safety valve are mounted on the upper cover of the pressurized vessel.

The capacity of the vacuum vessel is smaller compared to the other. There is a pressure sensor and a temperature sensor on its upper cover.

Both vessels are interconnected by two pipes of different section: a large diameter pipe that separates both vessels through a quick-acting valve, which will enable quick gas expansions, and a smaller diameter pipe that separates both vessels through a needle regulation valve, which will enable slow gas expansions.

The vessels can work either individually or jointly, allowing processes where air flows from a pressurized vessel to the atmosphere, from the atmosphere to a vacuum vessel or from a pressurized vessel to a vacuum vessel.

The unit includes a temperature sensor and a pressure sensor to measure the environmental conditions.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
