Construction of LVDT
The transformer and LVDT share a similar construction. It consists of one primary winding(P) and two secondary windings (S1 & S2). The primary and secondary windings are bounded by a hollow cylinder, known as the former. The primary winding is at the center and the secondary windings are present on both sides of the primary winding at an equal distance from the center. Both the secondary windings have an equal no. of terms and they are linked with each other in series opposition, i.e. they are wounded in opposite directions, but are connected in series with each other.
The entire coil assembly remains stationary during distance measurement. The moving part of the LVDT is an arm made of magnetic material.
Linear Variable Differential Transformer (LVDT)
The LVDT stands for Linear Variable Differential Transformer. It converts the Linear motion into an electrical signal using an inductive transducer. Due to its superior sensitivity and accuracy over other inductive transducers, the LVDT is extensively used in many different fields. For measuring linear distance, the linear variable differential transformer (LVDT) is a precise and trustworthy tool. Today, LVDTs are used in computerized manufacturing, robotics, avionics, and machine tools, combining research facilities, high-level analysis, and analysis to detect damage caused by massive rock deformation or other movements in the subgrade of old buildings or structures. physical structure. One try. This method is used to try to detect failure in concrete slopes and warn or correct the condition. One of the special problems with historical buildings is that they can easily be damaged by small deformations in the long run.
