Download Solution PDFLinear Variable Differential Transformer (LVDT)
- These devices are used to measure displacement.
- It is the most widely used inductive transducer that converts linear motion into an electrical signal.
- The LVDT is placed inside a stainless steel housing because it will provide electrostatic and electromagnetic shielding.
- LVDTs operate on the principle of a transformer.
- The transformer consists of a primary winding and two secondary windings wound on a cylindrical former.
- Both the secondary windings have an equal number of turns, and we place them on either side of the primary winding.
- The primary winding is connected to an AC source which produces a flux in the air gap and voltages are induced in secondary windings.
- A movable soft iron core is placed inside the former and the displacement to be measured is connected to the iron core.
- Both the secondary windings are connected in such a way that resulted in output is the difference between the voltages of the two windings.
