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.

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