PT100 sensor working principle – A Pt100 is a sensor used to measure temperature. It is one type of sensor which falls into a group called Resistance Temperature Detectors or RTD’s. Before understanding how the sensor works, it is worth looking at some of the terminology used as this is extremely useful to know when identifying a sensor.
What is the difference between PT100 and pt200?
Pt100 sensors. Temperature coefficient. The most common RTD sensor in process industry is the Pt100 sensor, which has a resistance of 100 ohms at 0°C (32°F). With the same logical naming convention, a Pt200 sensor has a resistance of 200 ohms and Pt1000 has 1000 ohms at 0°C (32°F).
How to test Pt-100 temperature sensor with resistance meter?
Test Pt-100 temperature sensor with resistance meter. Open the cap. Use multimeter (resistance measurement). Take out one wire from PT-100 connection box. Connect the multimeter between two connection pins.
What is RTD PT100 working principle?
PT100 Working Principle also known as RTD PT100 working principle – Although Platinum is a precious metal and therefore very expensive it gives the greatest linearity and stability of any other material. It also has the benefit of being extremely resistant to corrosion and chemical attack and is very stable at high temperatures.
