2. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   By far the most common devices used in industry have a nominal resistance of 100 ohms at 0 °C and are called Pt100 sensors ("Pt" is the symbol for platinum, "100" for the resistance in ohms at 0 °C). It is also possible to get Pt1000 sensors, where 1000 is for the resistance in ohms at 0 °C.

3. List of temperature sensors - Wikipedia

   en.wikipedia.org/wiki/List_of_temperature_sensors

   The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...

4. RTD - Wikipedia

   en.wikipedia.org/wiki/RTD

   Resistance Temperature Detector, a resistance thermometer; RTD is also used to rate or describe plywood manufacturing processes where RTD sensors significantly reduce the delamination caused by insufficient heating of the plywood during the press cycle.

5. Callendar–Van Dusen equation - Wikipedia

   en.wikipedia.org/wiki/Callendar–Van_Dusen_equation

   The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD). As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.

6. 3ω-method - Wikipedia

   en.wikipedia.org/wiki/3ω-method

   The 3ω-method can be accomplished by depositing a thin metal structure (generally a wire or a film) onto the sample to function as a resistive heater and a resistance temperature detector (RTD). The heater is driven with AC current at frequency ω, which induces periodic joule heating at frequency 2ω (since P = I 2 R {\displaystyle P=I^{2}R ...

7. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   Resistance temperature detector (RTD) Pyrometer; Langmuir probes (for electron temperature of a plasma) Infrared thermometer; Other thermometers; One must be careful when measuring temperature to ensure that the measuring instrument (thermometer, thermocouple, etc.) is really the same temperature as the material that is being measured.
