You will have to define LVDT as there are about 15 different common usages of the ACRONYM
The abbreviation LVDT stands for "Linear Variable Differential Transformer". In common usage, it is also just called a differential transformer, and measures linear displacement, i.e. movement.
First off, LVDT stands for linear variable differential transformer. The principle of the LVDT is that the physical energy is converted into electrical signals.
The linear variable differential transformer (LVDT) is a type of electrical transformer used for measuring linear displacement.
the physical energy is converted into electrical signal it's the principle of LVDT
The magnitude of the output voltage is proportional to the distance moved by the core (up to its limit of travel), which is why the device is described as having a "linear" response to displacement. The coils are connected in reverse series, so that the output voltage is the difference (hence "differential") between the two secondary voltages.

at 1 khz is .6volts
I think a secondary wife is called a 'concubine'
Output voltage at the null position is ideally zero. But because of harmonics in the excitation voltage and stray capacitance coupling between primary and secondary usually some nonzero voltage exists at null voltage. This is called residual voltage. If it is less than 1 % of full scale output voltage ( which is the normal case) it is in the acceptable limits.
it transforms linear motion into electrical signal..and the best example is LVDT. :)
