What do you think about thermocouples as a method to measure temperature?

Solution

Thermocouples are the most widely used temperature sensors, because of their simplicity, ruggedness, low cost, wide range and interchangability.

A thermocouple consists of two dissimilar metals, joined together at one end, and produce a small unique voltage at a given temperature. This voltage is measured and interpreted by a thermocouple thermometer.

Thermocouples come under the category of contact thermometry i.e. thermocouple always remains in contact with the device under test. Thermocouples are widely used in science and industry because they\'re generally very accurate and can operate over a huge range of really hot and cold temperatures upto 2600 ^oC.
