LDC1612: Using unshielded inductor as sensing coil

Part Number: LDC1612

Planning to use the device in conjunction with unshielded inductor instead of the PCB antenna / coil - in a bid to reduce to footprint and increase detection range. The application is to detect metal loss in carbon steel pipe. Any suggestions / thoughts on if

1. If I may use an unshielded inductor for the above mentioned reasons in my application?

2. Is LDC1612 the best device for my application?

Thanks,

Vik

  • Hi Vik,

    Please clarify what do you mean by metal loss in a pipe. Are you trying to measure wear or the pipe getting thinner?

    1) Yes, you can use unsheilded inductors, although be careful with ferrite core inductors, as they can constrain the magnetic field from reaching the target.

    2) Please clarify the desired sensing so that I can answer this question.

    Regards,

  • Thank you Chris for the response.

    The objective is to detect and measure metal loss in a piece of metal generally as a result of corrosion.

    1. Point noted.

    2. The minimum diameter of the metal loss I would like to be able to detect is 5mm. The minimum depth of loss I would like to find is 0.5mm. Desired Maximum sensing range is 20mm

    Detection material – Carbon steel

    Appreciate the help very much
