Thermocouple
DESCRIPTION
A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end, which produce a small unique voltage at a given temperature. This voltage is measured and interpreted by a thermocouple thermometer.
THERMOCOUPLE TYPES
Thermocouples are available in different combinations of metals or calibrations. The four most common calibrations are J, K, T and E. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple.
Element Type Range
Copper/Constantan (Simplex/Duplex) ‘T’ 100°C – 400°C
Iron/Constantan (Simplex/Duplex) ‘J’ 100°C – 800°C
Chromel/Alumel (Simplex/Duplex) ‘K’ 100°C – 1100°C
Platinum-13% Rhodium / Platinum (Simplex/Duplex) ‘R’ 200°C – 1600°C
The platinum resistance thermometers known as RTD operates on the principal of change in electrical resistance of platinum wire as function of termperature and it normally operates between the range of -200°C to + 500°C.
