Circult Design of Contact-free Sliding Micrometer

On Pointwise Observation , The contact-free sliding micrometer are instruments, suitable for highly accurate measuring distance-alterations between points in a rock-mass or soil-mass along the axis of a borehole.This paper describes the Principle of the sliding micrometer, on electromagnetic induction phenomenon .it also describes the system principle, the desigen of circle, the structure of electronic,the interface of the communication and the device . Aside from these,the paper describes the signal process, firmeware in the contact-free sliding micrometer.Finally it presents the specifications and the experimental data of the sliding micrometer.
