Full form of IVDT(Linear Variable Differential Transformer.
Working principle Of IVDT
The working principle of LVDT as a displacement transducer is based on mutual induction.
application of LVDT
1) Measurement of material thickness in hot or slab steel mills.
3) Jet engine controls in close proximity or exhaust.
4)LVDT is not suited for fact dynamic measurements on account of mass of the core.
Advantages of LVDT
1. Require extremely small force for operation hence very useful for use in small system.
2. Extremely sensitive.
3. Require small power for operation.
4. Frequency response is good.
