Englisch Begriff oder Satz: 30K less

Fan triggering
The fan switches independently of the heat sink temperature to full speed if the temperature rises above 250°C
If there are no other command signals from the heat sink temperature, the fan will switch off again at approx. 30K less.

K = speed? not kb
K = degrees?
if K is a variable, it is not defined in the text.

thank you very much

Klarstellungsanfrage(n) und Erwiderung

Tony M: 14:00 May 24, 2005: K is common as an abbreviation for 'degrees) Kelvin, and K are sometimes used in the specific context of describing a DIFFERENCE in temperature (cf. colour temperature in photography...) Plus 30 K is a logical enough value for temp. hysteresis -
Non-ProZ.com (asker): 14:23 May 24, 2005: thank you! so it's Kelvin - it makes sense for it to switch off at 220°C - not at -240°C

"30 degrees less than 250 degrees C = 220 degrees C"

temperatures in text range from 45°C - 250°C, nothing at or below zero
Non-ProZ.com (asker): 14:37 May 24, 2005: am rather confused about when it switches off - If the temperature drops below 45°C, the fan is switched off.
Kirill Semenov: 14:39 May 24, 2005: I think the text means the fan switches off at approximately 220°C -
Tony M: 15:38 May 24, 2005: Yes, I agree with Kirill: on at 250°C and off again at 220°C -

K=Kelvin (degrees C)

Erklärung:
Just a guess - K is a temperature scale which corresponds to degrees C minus 273 - so 0 degrees K = -273 degrees C. (-273 is Absolute Zero, nothing can be colder than that).

It's strange to use both measures in the same sentence, though, so this may not be right.

Apparently \'kelvins\' is accepted usage, and I have also seen \'degrees Kelvin\'. Your choice.

nonsensical in this context? [not for grading]

Erklärung:
I'm sorry but this makes no sense to me as a reader (and an engineer, I am not).
As Angela has pointed out, 30K (if K stands for Kelvin) is MINUS 243 degrees Celsius. I cannot imagine how that fits in there as a temperature or as a difference in temperature.
It would make much more sense to me if it said "30°C less", i.e. 220°C. But then I'm not an engineer.

--------------------------------------------------

Right, so what I understand Dusty to mean is that 30K is not to be interpreted as a temperature that would be converted to minus 243 degrees Celsius or as a difference of 243 degrees Celsius, but what engineers understand by 30 K (Wikipedia says there should be a space between the number and the symbol!) is \"a difference of 30 degrees Celsius\". Well, that\'s a new one for me. Thank you, Dusty.

Angela Dickson: that's not actually what I said - it's a *drop* of 30K - it does make sense when considered as a change from 250 degrees C.

31 Min.

-> I'm not misreprenting what you said. My reference was to the first two paragraphs of your explanation and was indeed an acknowledgment. The rest is entirely my own befuddlement.

Zustimmung

jrb: yes, I would guess that K is a mistake for C, or that there's some other mistake; it seems strange that they'd mix different scales

39 Min.

-> That would be a rather holistic approach, wouldn't it? :-)) Thanks.

Widerspruch

Tony M: Yes, they DO mix both scales, see my comments above...

45 Min.

-> Thanks. See my note.

Neutraler Kommentar

Kirill Semenov: as Dusty validly pointed out, Kelvins are often used to mark the temperature differences, not their absolute values
