Accurate temperature measurement performance of a radiation pyrometer cannot be affected, if the ?
Correct answer: C. Object and surrounding are at almost the same temperature
- A. Enhancement or attenuation of radiation occurs in the sighting path
- B. Object has varying emissivity
- C. Object and surrounding are at almost the same temperature
- D. Object is transparent
Explanation
Radiation pyrometer readings are affected by emissivity, sight-path absorption, transparency, and reflected surroundings. If the object and surroundings are at nearly the same temperature, reflected radiation has little effect on the measured temperature.
