they are devices used to measure the temperature, applying the temperature to RTD element. they are sensory devices.
What is the physical properties of a resistance thermometer
Resistance thermometer was invented by Calender-Van Duesen
It is a thermometer using the platinum wire as sensor (resistance thermometer); the resistance of the wire is proportional to the temperature. This type of thermometer is used under 600 0C.

A thermometer is for measuring temperature.
platinum resistance thermometer
Thermometer
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
1. Alcohol or spirit thermometer 2. Mercury thermometer 3. Liquid crystal thermometer 4. Quartz thermometer 5. Reversing thermometer 6. Resistance thermometer
Different thermometers make use of different physical properties, that change with temperature - for example, volume, electrical resistance, and others. The basic household thermometer simply has a liquid - previously mercury, nowadays usually colored alcohol - that expands when it is heated.
