I am looking for a specific thermistor. In my system, the thermistor strongly lies in the temperature (approx. 20%), and has no markings. From the documentation I only have its characteristics. What is the thermistor / model, markings, replacement? Size and manufacturer do not matter. The system will fit any suitable.
Can you measure its resistance at exactly 25 ° C and possibly other temperatures and compare with the graph?
That's what I did and at exactly known temperature, the actual value differed from that of the characteristics by 12K at 0 ° C. I will give you that the differences were different at other temperatures. You can draw a completely different characteristic in this way. At positive temperatures the difference was about 5K (20stC). The characteristics presented in the first post are appropriate for a functional thermistor. I think it will be a Thermistor MF52 10K F. It has very similar characteristics.
Thanks for posts and help. I think the problem is solved.
