Thermocouple Tradeoffs
What are the pros and cons of a thermocouple?
Expand Hint
The fundamental idea of a thermocouple is that two dissimilar metals are joined together at their two ends. If one end is placed on something hot, and the other end is placed on something cold, a potential difference, or voltage, develops. This difference can be measured by placing a voltmeter across the two hot/cold junctions.
Pros – cheap and easy to use, wide range of temperature measurements
Cons – not as accurate, wires can pick up ambient temperature if exposed
