PU-Wandler

15:41 Jul 7, 2019 

I do not believe that "PU-Wandler" is the only text in the document to translate. All other surrounding text would may make it clear that the article is dealing with pressure and/or pressure transducers, even the asker stated "there is no other context". This may be true regarding this term, but normally the title and abstract or the subject will guide the reader the right path.

With these more detailed statistics, one might argue that there is a prospect of the reader correctly 'guessing' the intended meaning.

Nevertheless, it is worth noting that — just as in German — there are some other options to consider in English that might reduce ambiguity.

One option would be "pV-transducer", which corresponds to the standard symbol used for pressure being lowercase (and italic) "p". I did not find an example of anyone actually writing this though.

The other option would be to insert a hyphen (or en-dash) or a slash. There are several examples of that in German (already cited) and some in English too.
"p☐v☐transducer": 23 hits¹ — https://www.bing.com/search?q=+"p☐v☐transducer"

"The air conduit is provided with an air pressure sensor 54, which is a pressure to voltage (“P/V”) transducer."
https://patents.google.com/patent/US7350593B1/en

On the other hand, it doesn't entirely remove ambiguity, as some instances of "P/V" & "P–V" on other pages stood for yet other things, such as "position/velocity" & "pressure–volume".

One last (two-page) note on this.
I stated that "PV transducer" could also stand for "photovoltaic transducer" [...].
Of course I didn't mean to suggest that the topic of the German text was photovoltaic cells, but rather that English-speakers might misinterpret that "PV" as meaning "photovoltaic" — if "there is no context".

It's not so easy to get good statistics about this, but consider the following:
"pv-transducer": 8100 hits¹ — https://www.bing.com/search?q=+"pv-transducer"
"pv-transducer"+voltage+pressure: 43 hits² — https://www.bing.com/search?q=+"pv-transducer" voltage press...

"pv-transducer"+solar: 27 hits — https://www.bing.com/search?q=+"pv-transducer" solar

¹ Some of the hits for the term "pv-transducer" alone are spurious, such as:
https://www.beyerdynamic.de/fileadmin/editors/downloads/Prof...

² Some of the hits for "pv-transducer"+voltage+pressure actually still use "PV" as an abbreviation for "photovoltaic":

Actually, I've just had another closer look at patent DE19746717C1, which I quoted in both my Answer and in a previous Discussion posting.
http://www.patent-de.com/19990610/DE19746717C1.html

While I already agreed that the context of the sentence
"Diesem Eingangsbereich wird das normierte analoge Druckistwertsignal, vom PU-Wandler 1 kommend"
was measuring pressure, and providing a commensurate electrical signal, I realise now that I overlooked the fact that whereas "PU-Wandler" appears once in the patent, the alternative form, "P/U-Wandler", appears five times in the same patent. For example:
"Um eine elektronische Einrichtung zur Ansteuerung eines Druckregelventils, mit einem über einen P/U-Wandler ermittelten analogen Druckistwertsignal [...].".
So I would now say that "PU-Wandler" is a misprint in that patent.

It still comes back to my point that the context is vital.
If we are allowed to speculate about misprints, and don't have any context, then we have to also consider "PA-Wandler" ( https://www.linguee.com/english-german/search?source=auto&qu... ), "PB-Wandler", and so on.

Hello, Johannes Gleim.

The difficulty I foresee is that even if the context happens to be conversion of pressure (via deformation) into an electrical signal (namely voltage), that doesn't guarantee that the German specification "PU-Wandler" wasn't providing more specific information about the nature of the sensor, i.e. that relevant parts of the sensor are constructed from PU (presumably polyurethane, but could be polyurea).

10:46 Jul 5, 2019 

I looked for your cited patent DE19746717C1:

Elektronische Einrichtung zur Ansteuerung eines Druckregelventils
:
Diesem Eingangsbereich wird das normierte analoge Druckistwertsignal, vom PU-Wandler 1 kommend, und das normierte analoge Drucksollwertsignal, vom Sollwertaufbereitungsglied 3 kommend, sowie der analoge Relativwert, vom Differenzverstärker 5 kommend, zugeführt.
http://www.patent-de.com/19990610/DE19746717C1.html

and found the following patent translation:

Electronic controller for a pressure regulation valve
:
This input region is the normalized analog actual pressure, coming from the PU converter 1, and the normalized analog pressure setpoint signal, coming from the set value processing member 3, and the analog relative value, coming supplied from the differential amplifier.
https://patents.google.com/patent/DE19746717C1/en

You will recognize that the translation from German to English is questionable und not reliable, see "input region", "analog actual pressure", "is" for “zugeführt" und you cannot trust the translation of "PU-Wandler" by "PU converter" being correct, either. But it confirms the subject of pressure-voltage conversion.

"p" is the Internationally standardized symbol for pressure, "U" that for voltages, except for anglosaxon countries, which use "V" instead of.
Transducers normally transduce physical values to electrical values.

You are right to note that "PV" may also mean "photovoltaic", but I think the context will make it clear (at least for the asker) that we are dealing with pressure-voltage transducers. I conclude this from the first question in the discussion, whether "PU-Wandler" can be translated by ""P/V converter". This proves that the asker understand "U", resp. "V" as "voltage" in the context.

You are also right to ask for more context, which must exist, e.g. other phrases, the document title, the subject, the purpose of translation or the field of business activities of the client.

07:45 Jul 5, 2019 

Yes, "U" could be the symbol for voltage ("V" in English).
https://de.wikipedia.org/wiki/Elektrische_Spannung

I'd be more inclined to this idea if the "p" were lowercase (though I realise not everybody abides by that standard) ...
https://de.wikipedia.org/wiki/Druck_(Physik)

... or if there had been a hyphen ("P-U-Wandler") or a slash ("P/U-Wandler").
Both of those variants can be found online
"Das mit diesem P-U-Wandler erzeugte elektrische Signal als Funktion des Arbeitsdruckes wird stetig mit der vorgegebenen Sollgröße des Steuersignals verglichen."
http://propventile.de/wp-content/uploads/2015/09/Allgemeines...

"Um eine elektronische Einrichtung zur Ansteuerung eines Druckregelventils, mit einem über einen P/U-Wandler ermittelten analogen Druckistwertsignal in einer Arbeitsleitung und einem vorgegebenen analogen Drucksollwertsignal, die beide als Eingangssignale einem 8-bit-A/D-Wandler zur Digitalisierung zur Verfügung stehen, [...]."
http://www.patent-de.com/19990610/DE19746717C1.html

Or if there were more context.

07:19 Jul 5, 2019 

The original Question stated: "I'm sorry, there is no context."
I took that literally.

If there's no context, and "PU-Wandler" can be interpreted as written to mean "PU transducer", then that's what I'd go with.

Sure, "PV transducer" is a term we can find online.
https://www.bing.com/search?q=+"PV transducer"
It might sometimes mean "pressure–voltage transducer".
It certainly sometimes means "photovoltaic transducer".
https://ieeexplore.ieee.org/document/7945273
Probably it could mean other things too.

This is also a patent translation (same German company Knorr-Bremse Systeme fuer Schienenfahrzeuge GmbH) as the patent I cited. You may know that automatic patent translations are peppered with errors and unreliable.

And your Ghits are wrong, too. That's what I've got:

"PU transducer" Ungefähr 113 Ergebnisse (0,25 Sekunden)
"PV transducer" Ungefähr 318 Ergebnisse (0,26 Sekunden)

Yes, it can, but P/V transducer is more frequent.
7 Ghits for P/V transmitter
234 Ghts for P/V P/V transducer

Hello, Yuu Andou.

Sure, it could be "P/V converter", or "A/D converter", or many other things....

But do you have a specific reason why you think it should be "P/V converter"? What would a "P/V converter" be, and why is it more likely than "PU transducer" (or "PU pressure transmitter")?

05:57 Jul 4, 2019 

Ich bin nicht sicher, ob dieser Begriff als "P/V converter" uebersetzt werden kann.
