4. Inductive

LVDT is an Inductive transducer. The linear variable differential transformer, or LVDT, transforms an object’s rectangular movement into the corresponding electrical signal.

### LVDT (Linear Variable Differential Transformer)

• The LVDT uses the transformer-based displacement calculation method to determine displacement.
• The LVDT converts a linear dislocation from a mechanical position into a relative electrical signal that contains information about direction and distance in the form of phase and amplitude.
• The linear variable differential transformer’s (LVDT) operating theory relies on mutual induction to convert nonelectrical dislocation energy into electrical energy.
• The primary coil, which is the inner one, is energised by an AC source as indicated.
• The two secondary coils receive the magnetic flux created by the main, which induces an AC voltage in each coil.

Applications:

• This transducer is also capable of serving as a backup transducer.
• The weight, force, and pressure are all measured using LVDT technology.
• Some of these transducers are employed in pressure and load calculations.
• LVDTs and servomechanisms are mostly employed in industrial settings.
• other uses, including hydraulics, automation, satellites, aircraft, and power turbines.
