Introduction:
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.
