  2. 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.

  3. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper ...

  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. 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 ...

  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. Steinhart–Hart equation - Wikipedia

    en.wikipedia.org/wiki/Steinhart–Hart_equation

    Finding temperature from resistance and characteristics [ edit ] The equation model converts the resistance actually measured in a thermistor to its theoretical bulk temperature, with a closer approximation to actual temperature than simpler models, and valid over the entire working temperature range of the sensor.

  8. Balco alloy - Wikipedia

    en.wikipedia.org/wiki/Balco_alloy

    It is used for making low cost resistance temperature sensors. It consists of 70% nickel and 30% iron. Balco is Carpenter Technology Corporation's brand name for this alloy consisting of 70% nickel and 30% iron. It is also sold by Harrison as "Hytemco". Its principal use is for resistance thermometers (resistance temperature detectors). These ...

  9. 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.
