Vapour actuated pressure spring thermometer does not require ambient temperature compensation. Ambient temperature compensation is provided in gas or liquid expansion pressure spring thermometer by__________________?
Correct answer: D. All A , B & C.
- A. Making the volume of thermometer bulb as large as conveniently possible
- B. Reducing the volume of the capillary to a minimum
- C. Reducing the volume of the receiving element to a minimum
- D. All A , B & C.
Explanation
Ambient-temperature effects are reduced by making the bulb volume large and the capillary and receiving-element volumes small, so most of the system's expansion response comes from the measured bulb. Therefore, all three listed design measures provide compensation.
