  2. Pyrometer - Wikipedia

    en.wikipedia.org/wiki/Pyrometer

    The tuyère pyrometer is an optical instrument for temperature measurement through the tuyeres, which are normally used for feeding air or reactants into the bath of the furnace. A steam boiler may be fitted with a pyrometer to measure the steam temperature in the superheater.

  3. Wedgwood scale - Wikipedia

    en.wikipedia.org/wiki/Wedgwood_scale

    Louis-Bernard Guyton de Morveau used his pyrometer to evaluate the temperature scale of Wedgwood and came to the conclusion that the starting point should be significantly lower, at 517 °F (269 °C) instead of 1,077.5 °F (580.8 °C), and that the steps should be nearly halved from 130 °F (72 °C) to no more than 62.5 °F (34.7 °C). However ...

  4. Pyrometric cone - Wikipedia

    en.wikipedia.org/wiki/Pyrometric_cone

    The pyrometric cone is "A pyramid with a triangular base and of a defined shape and size; the "cone" is shaped from a carefully proportioned and uniformly mixed batch of ceramic materials so that when it is heated under stated conditions, it will bend due to softening, the tip of the cone becoming level with the base at a definitive temperature.

  5. Pyrometric device - Wikipedia

    en.wikipedia.org/wiki/Pyrometric_device

    Pyrometric devices gauge heatwork (the combined effect of both time and temperature) when firing materials inside a kiln.Pyrometric devices do not measure temperature, but can report temperature equivalents.

  6. Thermometer - Wikipedia

    en.wikipedia.org/wiki/Thermometer

    An infrared thermometer is a kind of pyrometer . All objects above absolute zero emit blackbody radiation for which the spectra is directly proportional to the temperature. This property is the basis for a pyrometer or infrared thermometer and thermography. It has the advantage of remote temperature sensing; it does not require contact or even ...

  7. Temperature measurement - Wikipedia

    en.wikipedia.org/wiki/Temperature_measurement

    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.

  8. Infrared thermometer - Wikipedia

    en.wikipedia.org/wiki/Infrared_thermometer

    The most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface (actually a relatively small area determined by the D:S ratio). These usually project a visible red dot onto the center of the area being measured that identifies the spot being measured, but plays no ...

  9. Exhaust gas temperature gauge - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas_temperature_gauge

    An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).
