Why would the clipped voltage affect LVDT operation? I don't believe that this is the case. The answer might depend on the details of synchronous rectifier used as receiver. Level stabilisation would be wanted however, because the drive voltage acts as scaling factor for the displacement measurement.
Hi,
You need to isolate the circuit why don't you try with isolater.
Don't know the details of your LVDT transducer, but a usual type has zero output in the center position, a simple rectifier can't determine if the sensor is moved to the left or right.I am using full bridge rectifier at receiver end and a capacitor, which is use to read DC level
If you want a precision LVDS, the frequency, amplitude and ratiometric detection is critical, so it doesn't change with core loading changes from motion.
clipping is not allowed.
For 0.1% typical accuracy on position use this.

For 25 or worse % accuracy
Try this.

Using a 10W audio power amp with a stable signal to drive it.
An electronic circuit like your oscillator does not have a neutral. An electrical circuit has live, neutral and ground wiring.
You should learn that your circuit is wrong to be a Wien Bridge oscillator:
1) R1 and R3 must have the same value.
2) The gain must be a little more than 3 times.
3) An automatic level control circuit must be added so that the output level does not keep rising until the opamp produces clipping.

Sine wave, AC circuit and Neutral?? Are you trying to make an inverter with a sinewave output? This way makes a heater that wastes a LOT of power from the battery.
But you could use a comparator to compare this sinewave (when it has its level stabilized) with a high frequency triangle wave and the output of the comparator will be Pulse Width Modulation making an efficient inverter.
Input current of what?someone know how to find , input current
Unfortunately there's no driver coil impedance given, but 12 mA maximum is obviously the current specification.
I wonder where you got the 10 V rms driver voltage specification in post #5. I can't see it in the datasheet.
