SUMMARY

Optical pyrometers offer significant advantages such as non-contact measurement, ruggedness, and the ability to operate at high temperatures with a wide bandwidth. However, they also present disadvantages, including low sensitivity and poor time response. Additionally, the object being measured must be sufficiently hot to emit visible radiation, and there can be systematic errors due to differences in emissivity between the pyrometer filament and the object.

PREREQUISITES
  • Understanding of optical pyrometry principles
  • Knowledge of emissivity and its impact on measurements
  • Familiarity with temperature measurement techniques
  • Basic concepts of thermal radiation
NEXT STEPS
  • Research the principles of emissivity and its effects on optical pyrometry
  • Explore advanced optical pyrometer models and their specifications
  • Learn about calibration techniques for optical pyrometers
  • Investigate alternative non-contact temperature measurement methods
USEFUL FOR

Engineers, researchers, and technicians involved in high-temperature applications, as well as anyone interested in non-contact temperature measurement technologies.

Hello I really want to know what the advantages and disadvantages of optical pyrometers are?


Thanks a lot
 
Science news on Phys.org
+ Cheap, rugged, high temperature, wie bandwidth
- Low senstitvity, poor time response.
 
What mgb_phys said, and ...

Advantage:
non-contact measurement.

Disadvantage:
object must be hot enough to radiate visibly
systematic error from emissivity difference between pyrometer filament and object
