6.2.1. Linear Variable Differential Transformer (LVDT)

Try these first

1. 1.

   What does LVDT stand for?

   Hint

   Think about what it measures related to position.

2. 2.

   What principle does an LVDT operate on?

   Hint

   It involves magnetism and electricity.

3. 3.

   What principle does an LVDT utilize?

   • Mechanical pressure
   • Electromagnetic induction
   • Hydraulic force

   Hint

   Think about how it measures displacement.

4. 4.

   True or False: LVDTs require physical contact to measure displacement.

   • True
   • False

   Hint

   Consider the design of the sensor.

5. 5.

   Given a bridge expansion design that utilizes an LVDT for monitoring, propose a setup that includes the positioning of the sensors for maximum effectiveness.

   Hint

   Think about factors affecting the expansion.

6. 6.

   An LVDT measures a linear displacement of 0.01 meters. If the output voltage changes linearly from 0 to 10V with the range from -0.02m to +0.02m, what is the displacement voltage at 0.01m?

   Hint

   Use linear interpolation formula based on given ranges.
