what's the difference between a resistance thermometer and a Thermistor? Weedwacker 203.214.123.115 (talk) 12:44, 11 May 2008 (UTC)[reply]

From the thermistor page: Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals. The temperature response is also different; RTDs are useful over larger temperature ranges, while thermistors typically achieve a higher precision within a limited temperature range. Thermistors are also more subject to self-heating effects than resistance thermometers.

The reference to "alpha" in the "Temperature to resistance equation" section does not connect. Where is alpha? Torsionalmetric (talk) 13:50, 10 July 2008 (UTC)[reply]

===========

Even metal clad RTD are easily broken when subjected to physical shock or distortion (flexing). Sponsion (talk) 14:30, 25 June 2010 (UTC)[reply]

I would prefer if we dropped the lower case "s" and refer to "RTD" in the singular. When writing "RTD" in technical papers, the "s" is inherent or implied within RTD and is therefore redundant.

E.g., "RTDs resistance change are relatively linear over extensive temperature ranges." This may be written as "RTD resistance change is relatively linear over extensive temperature ranges."

If no one objects, I will eventually edit the article to remove the lower case "s"; i.e., I will change (RTDs) to (RTD) and correct the subject verb agreement. Sponsion (talk) 14:30, 25 June 2010 (UTC)[reply]

The resistance value for the PT100 RTD at T=55C appears to be an outlier. The value listed in the table is 121.49, but a value of 121.32 would fall closer to the curve described by the other values. — Preceding unsigned comment added by 108.7.96.172 (talk) 22:13, 4 August 2012 (UTC)[reply]

This article needs to be either renamed or updated to include thermistors. A thermistor IS a resistance thermometer. Moreover, there are more thermistors produced and used commercially than either PRTs or thermocouples.

Perhaps the article should be renamed as "Platinum resistance thermometer", especially as other RTD types (most notable is nickel) are also omitted. 71.228.106.24 (talk) 19:59, 11 July 2010 (UTC)[reply]

The section "Wiring configurations" contains completely useless information. Do not confuse the 2-, 3-, 4-wire resistance measurements with the Wheatstone bridge measurement! The allowable cabling length that you mention is wrong! Nobody applies 3 wire configuration for example the length of 500 m. For this length use a transmitter!

Please correct your article, because the "Wiring configurations" section is completely wrong! — Preceding unsigned comment added by 82.131.179.39 (talk) 05:27, 13 May 2013 (UTC)[reply]
