Inductive transducer

Hi,

I have a inductive transduver and I need convert the signal of transducer to a current/voltage signal.

I find this IC: http://www.ti.com/lit/ds/symlink/drv401-ep.pdf 

Does anyone know a IC more simple? Because this IC has PWM output for example, that I don´t need.

I need convert the signal of inductive transducer for a signal that I can process.

Thank you!

  • Ricardo,

    The DRV401 is intended to work with a very special current sensor so I doubt that you would find it useful.

    Can you explain what type of transducer you have? What are you sensing? Do you have information such as a data sheet on the transducer?

    Regards, Bruce.

    Hi,

    Thanks for your answer.

    I haven´t technical information about my transducer. Is a inductive transducer, that measure linear distance with a relutance variable. The connection with a transducer are two wire...

    Thank you!

    Ricardo,

    It is difficult for us to provide meaningful advice without information on the transducer.

    Most reluctance distance sensors have some sort of AC excitation from a second coil of some type. Is this the case? Other reluctance sensors have a permanent magnet that provides excitation but they sense motion of, for example, a toothed wheel.

    In any case, a two-terminal inductive sensor must provide an AC voltage output. A simple voltage amplifier using an op amp would would be a good start. If you can provide more detail such as frequency, voltage level, etc, we may be able to offer more advice.

    Regards, Bruce.

    Hi,

    Thanks for your answer.

    In this case, the transducer doesn´t has AC excitation or other type of excitation. A two-terminal provide the value of a variable coil. I think that is how a potentiometer: with variation of distance, the transducer variable a induction (instead resistance in potentiometer).

    Thank you!

    Ricardo,

    Sorry, but we cannot provide any help without information on the transducer.
