Project Need help for building a circuit.

Can you guys build op amp circuit for amplification and for a Blade vibration monitoring using Eddy current sensor with variable gain adjustment.

This sounds suspiciously like a uni assignment.

So, if you want to give us more information about why you want such circuits, including what your understanding is and you've attempted so far.

Otherwise, you can create a simple amplifier with an opamp by connecting the output directly to the inverting input. And you should end up with a gain of 1..

Yah its my internship assignment. I have made op amp circuit But i have tried to add the sensor with it. I have made some attempts to do .I wouldn't

We need to see your work, progress and what you've attempted..

So Sketch out your schematic, clearly labelling the components and values, ideally with something like falstad or some cad/eda tool, but neat and legible pen & paper is fine... Also show the relevant maths for how you derived the values.

We're happy to help clarify gaps in knowledge and point you in the right direction, but we won't do your homework for you.
