Output of LVDT
- The output of a Linear Variable Differential Transformer (LVDT) is an AC voltage that is proportional to the displacement or position of its core.
- A zero-differential output voltage is produced when the core is in the center, or null position, where the induced voltages in the two secondary coils are equal. The induced voltages in the secondary coils become unequal as the core moves away from the null position, and the differential output voltage increases proportionately.
So in a nutshell we can conclude that the output of an LVDT is an AC voltage and the magnitude and other measurements of this output voltage provide insightful information about the direction and amount of displacement which is later inspected and fixed if any problem is detected.
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.
