Temperature Measurement Sensors Pdf

A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor.
Temperature measurement sensors pdf. Thus for known reference temperature and known thermocouple wire materials output voltage vo can be used to measure temperature. Temperature is not equal to tr vo will be non zero. The output power is almost entirely provided by the measured signal without an excitation voltage. Commercial thermocouples are inexpensive interchangeable.
