Advantages, disadvantages and applications of radiation pyrometer

There are some advantages of radiation pyrometer which are given below.

• The radiation pyrometer has high output and moderate cost.
• It has ability to measure high temperature.
• It has fast speed response.
• It has good stability.
• It has no physical contact with target of measurement.

There are some disadvantages of radiation pyrometer which are given below.

• The radiation pyrometer is complex in nature.
• It has non linear scale.
• It has possible errors due to pressure to intervening gases or vapours that absorb radiation.
• Emissivity of target material affecting measurement.

There are some important applications of radiation pyrometer which are given below.

• The radiation pyrometer is used for temperature above the physical operating range of thermocouples.
• It is used for measurement of temperature in exhaust, flues etc. in heating system.
