TRTC Computer Controlled Thermal Radiation and Light Radiation Unit



The Computer Controlled Thermal Radiation and Light Radiation Unit, "TRTC", has been designed to demonstrate the laws of radiant heat transfer and radiant heat exchange.

It basically consists in two independent parts. One of the parts is for the light radiation experiments and another part is for the thermal radiation experiments.

The elements provided with the unit allow making the measuring of the temperature, radiation, intensity of light and the power in the heating element or bulb.

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.



  1. Inverse of the distant square law for the radiation.
  2. Stefan Boltzmann Law.
  3. Emission power I.
  4. Emission power II.
  5. Kirchorff ’s Law.
  6. Area factors.
  7. Inverse of the distant square law for the light.
  8. Lambert’s Cosine Law.
  9. Lambert’s Law of Absorption.
  10. Thickness effect of the absorption phenomena.
  11. Sensors calibration


  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the TRTC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the TRTC unit process.
  9. By using PLC-PI additional 19 more exercises can be done.
  10. Several other exercises can be done and designed by the user.
