A resistance temperature detector, or resistance temperature device (both of which are abbreviated RTD), is a way to measure the temperature of a substance using this effect. As the temperature changes, the resistance of a thin wire increases. Figure 1 shows several commercial, threaded RTD probes. What is a Resistance Temperature Detector (RTD)?

A resistance thermometer is commonly used across many industries. It measures the temperature using the electrical resistance of the wire. The main component used in the construction of a resistance temperature detector is the resistance wire; a pure material, made up of platinum, copper, or nickel because of the suitable properties.

The four wire resistance thermometer configuration even further increases the accuracy and reliability of the resistance being measured. In the diagram above a standard two terminal RTD is used with another pair of wires to form an additional loop that cancels out the lead resistance.

A resistance thermometer is used for temperature measurement. It is also called a resistance temperature detector. An RTD is basically a sensor that consists of fine wire wrapped around a glass or ceramic material and various other constructions are also used. The wire used is typically made of copper, nickel or platinum.

Note! - there are also PT1000 sensors with resistance 1000 ohms at 0 °C. The linearization equation for the Pt100 thermometer is. R t = R 0 (1 + A t + B t 2 + C (t - 100) t 3) (1) where. R t = resistance at temperature t (ohm) R 0 = resistance at temperature 0 o C (ohm) t = temperature (o C) A = 3.9083 10 –3. B = –5.775 10 –7

Temperature Dependence of Resistance. As mentioned in the formula above, the resistance of a material. depends on its resistivity, shape, and size. Resistance of a material depends on how the shape changes with temperature and resistivity variations with temperature. Resistivity behaves differently with temperature for different materials.
