Temperature Sensors
-
A Thermocouple consists of two electrical conductors of dissimilar material connected at one end (the hot junction); the two free ends are connected to the measuring instrument via a reference junction (the cold junction). The connection of these two materials provides an electromotive force (emf) proportional to the temperature being measured.
-
A Resistance Thermometer is a temperature sensor constructed from resistance wire wound into an element. It is used to measure temperature by means of a change in the electrical resistance with a rise or fall in temperature.
