  • The exercises assist the student in understanding the Second Law of Thermodynamics
  • The relationship between pressure, volume and temperature can be explored and used to determine other thermodynamic properties
  • The different responses resulting from fast or slow changes in a process and the relationship between the pressure and temperature of air can be observed
  • LxWxH: 650x550x700 mm
Technical Specification
The apparatus consists of two interconnected rigid vessels, one equipped for operation under pressure and the second under vacuum. An electrically operated air pump connected to the top of the vessels, together with valves and tapping’s enables the appropriate vessel to be pressurised or evacuated as required to suit the teaching exercise. The vessels can be used independently or together to enable different thermodynamic processes to be evaluated. A pressure sensor connected to each vessel and a temperature sensor inside each vessel permit the changes in the properties of the air contained within the vessels to be monitored continuously. Both vessels are constructed from clear rigid plastic, which affords light insulation between the air inside the vessel and the surroundings to reduce heating/cooling. This also enables each vessel and its contents to return to ambient temperature reasonably quickly. HT-806 | Ideal Gas Expansion Demonstration Unit SCADA system fully instrumented and computer controlled via USB / Ethernet interface / WiFi to record / set process parameters and to perform related thermodynamic calculations. . The idea of controlling any process variable and supervise possible anomalies offer great advantages if they are compared to manual procedures or process which lack of such technology. Besides, the experiments are carried out more effectively. The final result reliability is much higher without doubt, therefore the work done by the researcher possess a higher credibility. SCADA applications contain large amount of tools which are useful particularly to the research and the studied area such as Analyzing Data in detail once the experimental process has concluded, controlling the automatically the experiments or recording the events while the tests are performed.
Data Storage
The data are stored in a data base either in file format supported by third party software. The data can be represented both numeric format or graphic format like their trends and distributions independently the way it is used. As being available for the users anytime allows different tests to be compared and reach conclusion more truthful.
Control Algorithm
The control algorithm codification about the process offers uncountable interesting points compared to manual actions. The parameters can be controlled as in the case of any hardware element programmatically and with total independency of SCADA architecture used. Not only saving time is achieved but it is perfected over the implemented methodology and major exhaustive control for variables which are take part of the experimental process.
Warning and Alarms
Warning and alarms during tests add great value, especially, to avoid industrial machines are damaged, as case of the individual are exposed to hazard situations. They are great benefit too because they allow to monitor the variables status which are subjected without physical presence exits.
