Solved Examples on LVDT
1. An AC LVDT (Linear Variable Differential Transformer) is characterized by the following parameters: Input = 6.3 V, Output = 3.2 V, and a range of ±0.5 inches. Determine the following:
- Calculate the output voltage concerning core position for a core movement ranging from 0.45 inches to -0.30 inches.
- Find the output voltage when the core is positioned at -0.25 inches from the center.
Given that a 0.5-inch core displacement results in an output voltage of 3.2 V, a 0.45-inch core movement can be calculated as (0.45 * 3.2) / 0.5 = 2.88 V. Similarly, for a -0.30-inch core movement, the output voltage is determined as (-0.30 * -3.2) / (-0.5) = -1.92 V.
To find the output voltage for a -0.25-inch core movement, the calculation is (-0.25 * -3.2) / (-0.5) = -1.6 V.
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.
