Thermistor calibration
Posted: Tue May 22, 2012 3:57 pm
This is a picture of the fried thermistor together with a new one:
I need to calibrate the thermistor so that the graphs I post are meaningful. To see how the thermistor performs I need two standard temperatures. Water offers an easy way to calibrate temperature. This is the setup to measure the temperature at 100°C and 0°C:
The plastic bag is there to protect the thermistor from the water.
And the resulting graph:
Conclusion:
Thermistor looks good at 0°C but at 100°C it only shows 96°C.
I'll have to find a way to correct the tables now.
