Definition

1. Noun:
   • A thermometer designed to measure high temperatures: A pyrometer is an instrument used to measure temperatures that are too high for ordinary thermometers, typically those above the range of liquid-in-glass or thermocouple thermometers used for lower temperatures. It often works by detecting the thermal radiation emitted by the object.

Usage Examples

• Noun:
  • The engineer used a pyrometer to check the temperature of the molten metal.
  • Accurate temperature control in the kiln is possible with a modern optical pyrometer.

Advanced Usage

• "Optical pyrometer": A type of pyrometer that measures temperature by comparing the intensity of light emitted by the hot object with that of a calibrated internal source.

  • The scientist calibrated the optical pyrometer before taking measurements of the star's surface.

• "Radiation pyrometer": A pyrometer that determines temperature by measuring the thermal radiation (infrared) emitted from an object.

  • The radiation pyrometer can measure the temperature without making contact with the surface.

Variants and Related Words

• Pyrometric (adj): Relating to the measurement of high temperatures.

  • The pyrometric data was recorded every minute.

• Pyrometry (n): The science or practice of measuring high temperatures.

  • His research is in the field of industrial pyrometry.

Synonyms

• High-temperature thermometer: A general descriptive synonym.
• Radiation thermometer: Specifically for pyrometers that use radiative principles.
