FAQ
What is the Pt100?
A Pt 100 is a type of resistance temperature sensor made using a Platinum element with a resistance of 100 ohms @ 0℃ and typically with a 38.5 ohm fundamental interval. PT100 platinum resistance thermometers. Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from –200 to +850 °C). Standard sensors are are available from many manufacturers with various accuracy specifications and numerous packaging options to suit most applications.
What is difference between RTD and PT100?
There is no difference a PT100 is a version of a RTD (resistance temperature detector). What is an RTD? A resistance temperature detector, also known as an RTD or resistance thermometer, is a type of temperature sensor.
How does Pt100 temperature sensor work?
The key word is “resistance” because Pt100 measures temperature by using the change in resistance to represent the temperature value. For Pt100, the resistance is 100Ω at 0°C and 145.5Ω at 100°C. Therefore, the resistance change per degree Celsius change is 0.455Ω.
