PT100 Waterproof Temperature Sensor Platinum Resistance Probe

Pt100 is a platinum thermal resistance whose resistance is proportional to the change in temperature. The relationship between the resistance of PT100 and temperature is: when the temperature of PT100 is 0 °C, its resistance is 100 ohms, and its resistance is about 138.5 ohms at 100 °C. Its industrial principle: When the PT100 is at 0 degrees Celsius, its resistance is 100 ohms, and its resistance will increase at a constant rate as the temperature rises.The resistance value and temperature of the metal thermal resistance can generally be expressed by the following approximate relationship, that is,Rt=Rt0[1+α(t-t0)] Where Rt is the resistance at temperature t; Rt0 is the corresponding resistance value at temperature t0 (usually t0 = 0 °C); α is the temperature coefficient. The relationship between the resistance and temperature of the semiconductor thermistor is Rt=AeB/t Where Rt is the resistance at a temperature of t; A, B depends on the constant of the structure of the semiconductor material.
