Detailed Solution
Download Solution PDFThermocouple:
- The thermocouple is an electrical device containing junctions of two dissimilar metal joints. It is used as temperature sensors.
- It works on the principle of the thermoelectric effect or the Seebeck effect which means which states that the temperature difference between two dissimilar electric conductors produces a voltage difference between them.
- This potential difference is used to measure temperatures.
- Thermocouple types of instruments can be used for dc and ac applications.
- They can be used for measurements of currents and voltages at high frequencies.
- These instruments are very accurate well above a frequency of 50 MHz.
