3. Secondary Coil 2 S2

4. Ferromagnetic Core

5. Shaft

6. Shield

1. The ferromagnetic core is the moving component whose position within the shaft is sensed.

2.            It is surrounded by one primary winding in the center of the former.

3.            The two secondary windings are equal and opposite direction.

4.            If the left secondary windings in the clockwise direction, the right secondary windings will be in the anticlockwise direction.

5.            The net output voltages will be the difference in the voltages between the two secondary coils.

6.            A cylindrical shield protects the windings from damage.

7.            The two secondary coils are represented as S1 and S2.

8.            The induced voltages V1 and V2 in the two secondary are equal but anti phase.

1.    Working

The working of LVDT by splitting the cases into 3 based on the iron core position insulated former.

1.      Center or Null Position

2.      Right of Null Position

3.      Left of Null Position

CASE-1

® On applying an External force which is the Displacement.

® If the core reminds in the null position it without providing any movement.

® Then the voltages induced in both the secondary coils are equal.

® The core is in the centre V1 and V2 are equal and Opposite.

® Hence they cancel out and the Output voltage V₀ is zero.

                 V₀ = V1 – V2 = 0

CASE-2

® When an external force is applied and it the steel iron core tends to moves towards coil S2.

® V2 is increased but V1 is decreased in magnitude will each other.

® Therefore the net output voltage

V₀ = V2 – V1

® This is in phase with V2.

CASE-3

® When an external force is applied and it the steel iron core tends to moves towards coil S1.

® V1 is increased but V2 is decreased in magnitude will each other.

® Therefore the net output voltage

               V₀ = V1 – V2

® This is in phase with V1.

v The magnitude of V₀ is a function of the distance moved by the one core.

v Phase indicates as to in which direction it has moved.

If core is attached to a moving object, the magnitude of V₀ gives the position of that object.

Transducer

1. It may be defined as any device that converts energy is one form to energy in other form.
2. A transducer is an electronic device that converts energy from one form to another form. 3. A transducer converts a signal in one form of energy to a signal in another form.
Most of the transducers either convert electrical energy into mechanical displacement and/or convert some non-electrical physical quantity to an electrical signal.
In an electronic instrumentation system, the functions of a transducer are two fold
1. To detect or sense the presence, magnitude and changes in the physical quantity being measured.
2. To provideta proportional electrical output signal as shown in fig.
