Can't edit max thermistor temperature

Post by john »

Is there any way to edit thermistor reading to more than 125c?
I need to measure up to 150c, but cant change "property variable" from p125 to p150.

Hi, John.
Welcome to the forums.
125C is the maximum calibrated value you can use.
I believe it's not designed for higher temperatures as the temperature is calculated by linear interpolation, so it will start to become widely out of tolerance.
An alternative is to use a formula for temperature calculations based on the thermistor resistance value.
One such example can be found here.
I have found the method used within the flowchart to be surprisingly accurate.
