Question

Difference between optical pyrometer and total radiation pyrometer

Answer 1

Radiation pyrometer

Opticalpyrometer

1.Temperature is direct measured with the help of thermocouple.

1.Temperature is measured by comparing the brightness of hot body radiation at specific colour.

2.Emissivity of target may affect measurement.

2.Dust, smoke and thermal background radiation affect.

3.Chance of error is negligible.

3.Causing human error.

4.The radiation pyrometer has moderate cost.

4.The optical pyrometerhas high cost.

5.The output is directly given by thermocouple in terms of m volt.

5.The output is observed by human eye.

Answer 2

Answer:The radiation pyrometer has moderate cost. The optical pyrometer has high cost. Answer:The radiation pyrometer has moderate cost. The optical pyrometer has highhigh
