    methods to calibrate a temperature sensor

    How can I calibrate a temperature sensor ?
    It's a tool for sensor calibration?
    The calibration can be done using a oil bath ?
    The calibration can be made only by comparing the results with a "ideal" sensor ?
    How is that sensor calibrated ?

    Maybe you have some links, tutorials, manufacturiers...
    Any informations/comments are welcomed.

    Resistive sensor

    If the sensor is resistor you can express its resistance as follows:

    R=Rnom*(1+Kt_1*(T-Tnom)+Kt_2*(T-Tnom)^2)

    I have attached a excel file for calculation of the coefficient Rnom, Kt_1, Kt_2.

    Youi just have to measure the resistance of the sensor at three temperatures and to enter the dat in the fil.
