SUMMARY

Measuring the surface temperature of a filament bulb using a thermocouple is ineffective with contact methods due to the low thermal mass of the filament. Contact with the thermocouple sensor will cause the filament to equalize in temperature with the probe, resulting in inaccurate readings. Non-contact methods, such as infrared thermometers, are recommended for accurate temperature measurement of filament bulbs.

PREREQUISITES
  • Understanding of thermocouple types and their applications
  • Knowledge of thermal mass and its impact on temperature measurement
  • Familiarity with non-contact temperature measurement techniques
  • Basic principles of electrical resistance in filament bulbs
NEXT STEPS
  • Research infrared thermometers and their specifications for measuring filament temperatures
  • Learn about different types of thermocouples and their appropriate applications
  • Study the principles of thermal mass and its effect on temperature readings
  • Explore alternative temperature measurement techniques for delicate components
USEFUL FOR

Engineers, physicists, and hobbyists interested in accurate temperature measurement techniques for electrical components, particularly those working with filament bulbs.

Can some 1 pls tell me how to measure the surface temperature of the filament bulb with a thermocople, do you put the sensor on the surface or what. As i am new to this can u pls help. Thanks you

You will not be able to get a meaningful temperature of a filament with a contact method. The thermal mass of a filament is very low, contact with any object will cause the filament to equalize in temperature with the probe, thus you will not measure the correct temperature.

See my response to this same question in your previous post. Please do not double post.
