A silly question – why isn’t the resistance value of a thermal resistor an integer?
Thread Content
Why isn’t the resistance value of a thermal resistor an integer? For example, 100 ohms at 0 degrees and 600 ohms at 500 degrees. Isn’t that convenient?
The temperature coefficient of resistance of metals cannot be changed at will.
The resistance of thermistors at 0 degrees is always an integer; for example, the resistance of Pt100 at 0 degrees is 100 ohms, while that of Pt50 at 0 degrees is 50 ohms. The resistance at 0 degrees can be controlled through manufacturing, while the resistance at other temperatures is determined by the temperature coefficient of the thermoresistive material and cannot be set manually.
This question is very representative; form or result, which do you want?
It’s really absurd... Just like when people grow taller – can they jump from 1 meter to 1.2 meters to 1.5 meters in such a manner?
Hahaha, this is the first time I’ve seen a post from Hai Chuan that made me laugh out loud! I had some ideas, but I never dared to question the components; it seems that only by questioning things can one see problems more clearly. Haha, but I still think the original poster is very talented!
For example: converting RMB to USD (temperature vs. resistance value). Since the exchange rate is not an integer, when the RMB amount is rounded, the US$ amount is no longer an integer ； The same is true in reverse. @jiaguoyun
Since it’s absurd, there’s no need to say much – there are too many absurd things in the world. Never mind, never mind.
It’s a matter of materials – if you can find materials that are suitable enough and at a low cost, that would work; it might even save the need to design circuits
