Question

when the core of the LVDT is at the null location ideal output value of secondary is​

Answer 1

Answer:

This equation explains the principle of Operation of LVDT. When the core is at null position then the flux linking with both the secondary windings is equal so the induced emf is equal in both the windings. So for no displacement the value of output eout is zero as e1 and e2 both are equal

Answer 2

When the core of the LVDT is at the null location ideal output value of the secondary is Zero.

• LVDT stands for Linear Variable Differential Transformer.
• It is a standard electromechanical transducer that can convert the rectilinear movement of an object into a machine into a coherent electrical signal.
• LVDT line sensors are readily available that can measure motion as a few million to a few inches, but can also measure up to ± 30 inches (± 0.762 meters). The inner structure of the transformer consists of a central curve in the middle of a pair of second curves with the same wound, evenly spaced on the base.​
