A platinum resistance thermometer (PRT) is a piece of platinum wire which determines the temperature by measuring its electrical resistance. It is referred to as a temperature sensor. When manufactured carefully, these devices offer an excellent combination of sensitivity, range and reproducibility. PRTs work in the following way.

Up to 950°C, the platinum resistance thermometer is often used as a reference standard. Above that temperature, up to about 1750°C, a type S (platinum/rhodium-platinum) thermocouple is usually employed. Type K (chromel-alumel) thermocouples are also used as an alternative reference standard for temperature calibration up to 1000°C.

Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper

The requirements of the International Temperature Scale of 1948 for the purity and physical condition of platinum to be used in resistance thermometry are based upon the change in resistance between 0° and 100°C, this range being known as the fundamental interval: the ratio R100/R0is required to be greater than 1.3910.

The platinum thermal resistance (PTR) uses platinum for determining the temperature. It works on the principle that the resistance of platinum changes with the change of temperature. The thermometer measures the temperature over the range of 200°C to1200°C. The platinum is an unreactive metal and can easily be drawn into fine wires.

Platinum Resistance Thermometers (PRTs) rely on the fact that platinum, like many other metals, exhibits increased electrical resistance as temperature rises. For example, a conventional PRT designed to provide 100 Ω at 0 °C has a resistance in the neighborhood of 80 Ω at -50 °C and 120 Ω at 50 °C, or a sensitivity of about 0.4 Ω per degree.

The resistance of the platinum wire changes with a change in temperature of the gas or liquid. The maximum temperature measurable in continuous operation is 1000° K i.e.727° C. 4. This type of sensor has a positive temperature coefficient of resistivity as they are made from metals. These are also known as "resistance temperature detectors or RTD".
