A bimetallic thermometer as compared to industrial mercury in glass thermometer has almost the same_________________?
Correct answer: D. All a, b & c
- A. Temperature measuring range (- 40°C to 450°C)
- B. Accuracy (± 1% of span)
- C. Speed of response
- D. All a, b & c
Explanation
Industrial bimetallic and mercury-in-glass thermometers can have broadly comparable ranges, accuracy, and response characteristics in ordinary industrial service. The bimetallic instrument is preferred where greater ruggedness and remote mechanical indication are useful.
