Question
Download Solution PDFDirection: It consists of two statements, one labelled as Statement (I) and the other as Statement (II). Examine these two statements carefully and select the answers to these items using the codes given below:
Statement (I): The principle of the resistance strain gauge is that if gauge factor is known, the measurement of
Statement (II): The output of a LVDT is of the order of millivolt.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe gauge factor is defined as the ratio of per unit change in resistance to per unit change in length. It is a measure of the sensitivity of the gauge.
Gauge factor,
Where ε = strain = ΔL/L
Therefore, if the gauge factor is known, the measurement of
LVDT:
- LVDT (Linear Variable Differential Transformer) is an electromechanical transducer that can turn rectilinear motion into corresponding electric signal.
- In LVDT the output signal is AC voltage whose magnitude changes with the linear displacement of the core within the LVDT coil.
- The output of an LVDT is of the order of millivolt.
Therefore, both statement (I) and Statement (II) are individually true and Statement (II) is not the correct explanation of Statement (I)
