Explanation: The LVDT accelerometer consists of one primary and two secondary windings which are placed on either side of central code. The two ends of the core are connected with spring steel but these are already placed in a casing. If a core is exactly placed at the center, the voltage produced between primary and secondary windings will be exactly equal; this voltage is called as static field voltage. If any vibration occurs on the casings of the LVDT accelerometer, the core will either move upward or downward. Owing to this, the voltage is induced in the secondary coil according to the movement of the core. Now the difference in voltage arises in the output terminal. This output voltage is directly proportional to the vibration or acceleration.
