APPARATUS FOR DETECTING BURIED CONDUIT LINE

摘要

PURPOSE: An apparatus for detecting a buried conduit line is provided to grasp a position and a path of a buried conduit by installing an electronic indicator at the buried conduit, generating a magnetic field to the electronic indicator, and observing the magnetic field retransmitted from the electronic indicator. CONSTITUTION: A transmitter(100) is formed with an RF transmitter in order to generate a predetermined frequency. A loop antenna(110) has a shape of circular coil and is connected with the transmitter(100). The loop antenna(110) is used for oscillating signals generated from the transmitter(100). An electronic indicator(120) is installed at a conduit line. The electronic indicator(120) includes a receiving coil which is synchronized with a transmitting frequency oscillated from the loop antenna(110). An amplifier(130) is used for amplifying the transmitting signal which is sensed by the loop antenna(110). A display device(140) is used for indicating the presence of the electronic indicator(120) by using the amplified signal of the amplifier(130).
