Which of the following statements about the linear variable differential transformer (LVDT) is NOT true?
1
The LVDT can be used in all applications where displacements ranging from a fraction of an mm to a few cm have to be measured. Acting as a transducer, it can be used as a device to measure force, weight and pressure.
2
LVDT transducer can be used as a device to measure force, weight and pressure.
3
Power consumption in LVDT is high, it is around 100 watts.
4
LVDT is sensitive to stray (outside) magnetic fields.
