LVDT

What is a LVDT, and how does it work?

Hint
LVDT = Linear Variable Differential Transformer, which is a type of electrical sensor.
LVDT - Linear Variable Differential Transformer - is an electrical sensor that converts mechanical motion, vibration, or rotation into an electrical signal. It is typically used for measuring linear displacement.
