LDC1614EVM: Integrated inductance to digital evaluation board with reduced diameter coils?

Part Number: LDC1614EVM

Hi Team.

I have been using your LDC1614EVM Inductance to Digital Converter to measure displacement on a simplified test model. I’m now looking to increase the complexity of my model and integrate the sensing coils into my test rig. However, would like to reduce the outer diameter of the coil size to 4mm and measure displacement on the micrometer scale (i.e. sensitivity of about 1um), within an aqueous environment.

My background is mechanical entering and have fairly limited experience with electronics. Is it possible to buy an integrated Inductance to Digital Converter Evaluation Module with the sensing coils that I can snap off that fit that description?

Thanks,

Abi

Abigail,

Coil R on the LDC Reference Coil EVM is 4mm, so you can prototype using that. You can use the unused channels on the EVM to connect to Coil R (you can also break off the included EVM coils if you wish). Please note that the maximum distance the LDC1614 can typically see is about twice the coil diameter away, and you will see improved resolution the closer you get to the coil.
