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.

Most industrial resistance thermometer use a platinum element with a resistance of 100 ohms at 0°C, this resistance changes as the temperature changes.

Temperature measuring using a platinum resistance thermometer is simpler than with a gas thermometer. The thermometer has a temperature range of 200 to 1200° Celsius. The resistance-temperature connection is widely understood. IPRTs are built to last, and the cost of an IPRT is cheaper than that of an SPRT.

The resistance of a certain platinum resistance thermometer is found to be 2.56 Ω at 0∘C and 3.56 Ω at 100∘C. When the thermometer is immersed in a given 

Platinum resistance thermometer Pt100Ω "sheathed type". Heat resistance temperature of cladding material: 200°C, Tolerance: Class B, 3 wired. Model No 

The 670 Standard Platinum Resistance Thermometer consists of quartz sheath (recommended) and metal sheath models with Ro of 25.5 Ω, T° range: -200 to 670°C.

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.

Platinum Resistance Thermometers, commonly referred to as RTD Sensors, PRT Sensors or Pt100 Sensors, is a type of resistance temperature sensor used for a wide variety of temperature measurement applications. There are many types of Resistance Thermometer, but typically Pt100 (made using a Platinum element with a resistance of 100 ohms @ 0ºC

Its operations are carried out in such a way as to fully exploit the fast response of the thermistor and the high accuracy of the platinum thermometer. In addition, the system uses a strain gauge as a

2001/10/29 · Platinum resistance thermometers (PRT) are the most accurate of all thermometer types and cover a remarkably wide temperature range. This chapter begins with a tutorial explanation of the physical origin of electrical resistance, and then describes the properties, construction and instrumentation of PRTs for various applications. Emphasis is

Answer: The choice of metal depends on characteristics such as its temperature coefficient of resistance α, resistivity ρ, melting point and its resistance to corrosion and pollution. Platinum
