The bimetallic thermometer is inaccurate
Thread Content
Why do analog bimetallic thermometers have large errors, especially at sub-zero temperatures?
Bimetallic thermometers are field display instruments; they are similar to pressure gauges in that they aren’t given much attention, their price is low, and their quality is indeed not very good.
It’s from Tianjin Instrument Factory; those that cost 500 each don’t work either :(
If it’s not allowed, then it’s simply not allowed. . . You don’t want to agree, do you? ,,., hehehe:,P. . . Anyway, he doesn’t participate in any form of chain control; he has no parents or female friends either~~~ His face is also quite large, round like a pancake – it’s annoying, right? {:3_51:} . . Stop bullying him, please. . . I was wondering if you have a way to adjust it properly?
We used some imported ones; they are very accurate.
For values below 0, does one have to use a bulb thermometer?
A bimetallic thermometer is just a reference; don’t expect too much from it.
Has the sub-zero temperature reached the limit of the bimetallic thermometer’s range? Is it common to use the full scale range to determine the initial impact, by expanding the negative range a bit?
What era is this? We still use bimetallic elements? You know something called Pt100? It provides on-site display; it’s a bit more expensive, but it’s accurate!
