Help with this template Comments: edit – history – watch – refresh Sorry, thermistor and RTD is two different thing although it is using same theory and method but because of the material and withstand, it cannot be merged. futhermore, RTD artical is just fair but not too detail. If you want to merged, merged RTD artical with thermocouple.

[edit] Merge from R.T. Device

From reading the discussion below, it seems like this is no longer an issue, BUT thermistors and RTD's are NOT the same thing. They operate using the same principle ("large" changes resistance in resistance vs. temperature) but have very different response curves as can be seen on the fourth page of the application notes from General Electric's Thermometrics Division (http://www.gesensing.com/products/resources/whitepapers/ntcnotes.pdf). Not only are the actual physics underlying the resistance changes and the materials they are made from very different, but they are also sold as distinct devices by manufacturers. I think, therefore, that the tag for a merger of Resistance Temperature Device and Thermistor should definitely be removed. I feel like Resistance Temperature Device and Resistance thermometer should be merged though because Platinum Resistance Thermometers are definitely the largest subclass of RTD's. - Dborrero 15:50, 30 March 2007 (UTC)

Resistance Temperature Device and Resistance thermometer should be merged, as they are two articles about the same device. Thermistor, on the other hand, is a different device. While it would be helpful to reference the Thermistor article in Resistance Temperature Device, they should be on separate pages due to their differing operation.

Resistance Temperature Device needs to be merged into this article.—The preceding unsigned comment was added by Slashme (talk • contribs) .

So does Resistance thermometer.--Srleffler 20:44, 26 May 2006 (UTC)

• I agree that they need to be merged as suggested. A single article will be much easier to read and understand. I doubt that I would ever have found the resistance thermometer article without the merge notice, and it was the article with the information I was looking for. --W0lfie 15:36, 21 June 2006 (UTC)

• Resistance Temperature Device is a copy-and-paste from a National Instruments application note. I have listed it as a copyright violation, but I'll try to rewrite-merge the contents into this article. Han-Kwang 16:34, 2 July 2006 (UTC)

• I deleted Resistance Temperature Device as a copyright violation. I agree that the articles should be merged, but I think the name of the merged article should be resistance thermometer, which is the more common name by far according to Google results (60,300 vs. 171,000 or 74%). Unless there is a strong reason that a different name should be used, the most common name is preferred. Is there a resaon the title should be resistance temperature detector instead? I'll modify the merge tags and if someone objects, they can revert and say why here. -- Kjkolb 22:47, 12 July 2006 (UTC)

Try RTD temperature on Google: 1.2 million hits, plus 8 ads for buying them. Or RTD Pt (750 thousand). Google should not be trusted for multi-word searches, because skipping to results page 99 will show that Resistance thermometer actually has 768 hits, RTD temperature 734 hits, and RTD Pt 732 hits.

Google breaks down when you do this. It cannot be trusted to give anything close to the true number unique results when they are more than two or three hundred. Actually, even that many can be questionable. The problem can most easily be seen by searching for an extremely common word, like "home" or "the". According to Google, there are only 919 unique results out of 19.2 billion for "home" and 688 unique results out of 23.8 billion for "the". Another problem is that you are not using quotes, which helps to exclude irrelevant results when using multiple search terms. -- Kjkolb 12:42, 16 July 2006 (UTC)

Never too old to learn something new... I checked a catalog for electronics and process control hardware (RS components) and they had yet another term than the two we're discussing here. Han-Kwang 22:07, 16 July 2006 (UTC)

I am from power industry. Still the term used by is RTD and Pt 100. So my oppinion is to keep the artical. It does not matter duplication of the material. I think this artical should be more developed with test standard and colour coding etc. Janeth
