Principles of Thermometry - CSEC PHYSICS

The main advantages of the thermocouple thermometers are: the wire junction can be very small and needs very little heat to warm it up. This means that it responds very quickly to temperature changes and that it can be used in very small or precise locations. The output of the thermometer is an electrical signal which can be used to operate electrical equipment capable of giving warning of ...

Thermocouples Operating Principles

THERMOCOUPLES: THE OPERATING PRINCIPLE. A thermocouple is a device made by two different wires joined at one end, called junction end or measuring two wires are called thermoelements or legs of the thermocouple: the two thermoelements are distnguished as positive and negative ones. The other end of the thermocouple is called tail end or reference end ().
