The Temperature Measurement Unit, "TMT", 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).
- Determining concepts of temperature measurements and scales:
- Temperature scales: alcohol thermometer.
- Demonstration of thermometric properties and characteristic behaviour of different sensors:
- Peltier’s thermoelectric effect.
- Seebeck’s thermoelectric effect.
- Intermediate metals Law.
- Intermediate temperatures Law.
- Working with different temperature indicator devices:
- Vapour pressure thermometer.
- Bimetallic thermometer.
- Wet and dry bulb thermometer.
- Measuring precision, sensitivity and measuring errors of the different thermometers:
- Direct measurement thermocouple.
- Parallel association of thermocouples.
- Series association of thermocouples.
- Dynamic response:
- Platinum resistance thermometer.
- Introduction to calibration techniques of each system.
- Errors associated to a bad electrical connection.
- Calibration errors.
