Correct Answer - Option 4 : 1, 2 and 3

LVDT (Linear Variable Differential Transformer) is the most widely used inductive transducer that coverts the linear motion into the electrical signal.

Advantages of LVDT:

Linearity: The output voltage of this transducer is practically linear for displacements up to 5 mm (a linearity of 0.05% is available in commercial LVDTs).

Infinite resolution: The change in output is stepless. The effective resolution depends more on the test equipment than on the transducer.

High output: It gives a high output, therefore there is frequently no need for intermediate amplification devices.

High sensitivity: The transducer possesses a sensitivity as high as 40 V/mm.

Ruggedness: These transducers can usually tolerate a high degree of vibration and shock.

Less friction: There are no sliding contacts.

Disadvantages of LVDT:

  • Very high displacement is required for generating high voltages.
  • Shielding is required since it is sensitive to magnetic field.
  • The performance of the transducer gets affected by vibrations.
  • It is greatly affected by temperature changes.
