Descrição Geral

The Computer Controlled Temperature Measurement Unit, "TMTC", works as a temperature meter that uses different temperatures measuring devices to compare, check and analyze the temperature and how is the precision for the measure and for the device that the student has used.

This unit is used to study the different types of temperature devices, the temperature phenomenon when the student works with these types of devices (Peltier’s thermoelectric effect and Seebeck’s thermoelectric effect between others) and the difference when the student works with different device disposition (Direct measurement thermocouple, parallel association of thermocouples or series association of thermocouples, between others).

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. Determining concepts of temperature measurements and scales.
  2. Temperature scales: alcohol thermometer.
  3. Demonstration of thermometric properties and characteristic behaviour of different sensors:
  • Peltier’s thermoelectric effect.
  • Seebeck’s thermoelectric effect.
  • ntermediate metals Law.
  • Intermediate temperatures Law.
  1. Working with different temperature indicator devices:
  • Vapour pressure thermometer.
  • Bimetallic thermometer.
  • Wet and dry bulb thermometer.
  1. Measuring precision, sensitivity and measuring errors of the different thermometers:
  • Direct measurement thermocouple.
  • Parallel association of thermocouples.
  • Series association of thermocouples.
  1. Dynamic response:
  • Platinum resistance thermometer.
  • Thermistor.
  1. Introduction to calibration techniques of each system.
  2. Errors associated to a bad electrical connection.
  3. Calibration errors.
  4. 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/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 TMTC unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the TMTC unit process.
  9. Several other exercises can be done and designed by the user.
