Resistance Thermometer also called Resistance
Temperature Detector (RTD) is a temperature sensor that determines
the temperature to which it is subjected using the principle that the
resistance of a particular metal varies with changes in temperature.
Resistance thermometers types are classified with the abbreviation of the
material used for their construction followed by the nominal resistance value,
expressed in Ohm.
Normally resistance thermometers are identified with the initials of the
material used for their construction (Platinum = Pt, Nickel = Ni) followed by
their nominal resistance at a temperature of 0 ° C as Pt100, Pt500, Pt1000.
The construction of the sensing element or resistor can be wire wound,
spiral wound, or film wound. The configuration of a resistance thermometer can
be with 2, 3 or 4 connection wires depending on the temperature measurement
