pyroscope
Học thuậtThân thiện
Definition
Noun A scientific instrument that measures high temperatures by analyzing the color of the light emitted by a hot object. It is a specific type of optical pyrometer.
Usage
The word "pyroscope" is a technical term used primarily in physics, engineering, and industrial contexts. It refers to a device that determines temperature based on the principle that the color of thermal radiation changes with temperature.
Examples
- The technician used a pyroscope to measure the temperature of the molten metal without making contact.
- Accurate readings from the pyroscope are essential for monitoring the furnace's conditions.
- Early pyroscopes relied on comparing the color of an object to a heated filament.
Advanced Usage
- Conceptual Use: The term can be used more broadly to describe any method of estimating temperature by color observation, even informally.
- Example: "The experienced blacksmith acted as a human pyroscope, judging the iron's temperature by its glow."
Variants and Related Words
- Pyrometer (n.): A broader category of instruments for measuring high temperatures, which includes the pyroscope.
- Optical pyrometer (n.): A near-synonymous term for a pyroscope.
- Radiation pyrometer (n.): Another related type of temperature sensor that measures thermal radiation.
Synonyms
- Optical pyrometer
- Radiation thermometer
Related Terms and Concepts
- Pyrometry (n.): The science and technology of measuring high temperatures.
- Thermal radiation (n.): The electromagnetic radiation emitted from the surface of an object due to its temperature, which a pyroscope analyzes.
- Color temperature (n.): A characteristic of visible light, measured in Kelvin, which is directly related to the principle of how a pyroscope works.
Noun
- a pyrometer that uses the color of the light emitted by a hot object
