Abstract
A carrier for installing an RFID tag in a utility marker tube provides a centering plate fitting against an upper edge of the tube and oriented and positioned either by inner tube walls and/or the outer tube wall periphery to locate a downwardly extending transducer support tab holding the transducer within the tube. The centering plate may be held in place by a separate or integrated cap retaining the centering plate while sealing the tube against environmental contamination.
Claims10
An RFID marker system comprising:
- a tubular post of a radio-transparent polymer material adapted for partial insertion in the ground to extend upward therefrom, the tubular post providing outer walls defining an internal volume;
- a centering plate receivable at an upper end of the tubular post to be supported by the upper end of the tubular post;
- a transponder support tab attached to and extending downwardly from the centering plate when the centering plate is received at an upper end of the tubular post, the transponder support tab extending within the internal volume to present a vertically extending surface sized to receive an RFID tag thereupon;
- and
- an RFID tag attached to the vertically extending surface;
- and
- further including a cap having an upper wall and having at its perimeter downwardly extending walls adapted to slide over the outer walls of the tubular post of the upper end of the tubular post therein to capture the centering plate between a lower surface of the upper wall of the cap and an upper surface of the upper end of the tubular post.
