PT100 is a platinum thermal resistance, and its resistance will change with temperature. 100 after Pt means that its resistance value is 100 ohms at 0°C, and its resistance value is about 138.5 ohms at 100°C. How it works: When the PT100 is at 0 degrees Celsius, its resistance is 100 ohms, and its resistance will increase approximately uniformly as the temperature rises. But the relationship between them is not a simple proportional relationship, but should be closer to a parabola.
PT100 temperature sensor is a resistance temperature detector made of platinum (Pt), which is a positive resistivity. The relationship between its resistance and temperature change is as follows: R=Ro(1+αT), where α=0.00392, Ro is 100Ω (resistance value at 0°C), T is the temperature in Celsius. Therefore, the resistance temperature detector made of platinum is also called PT100 temperature sensor.
