A system includes a radio frequency identification (RFID) tag,36, embedded within a mineral extraction component, 32, (e.g. a drilling riser segment or other tubular component), a manual RFID antenna tuner, 40, comprising an input device, 42, (e.g. a switch, a knob or an electronic user interface) configured to receive settings indicative of a desired inductance and electronic circuitry, 44, configured to adjust an inductance of an RFID antenna, 38, based on the settings. The manual RFID antenna tuner, 40, may vary the inductance through a frequency range of 30-300 kHz (low frequency). An RFID reader, 46, may be electrically coupled to the manual RFID antenna tuner, 40, and configured to communicate with the RFID tag, 36. The RFID antenna, 38, may include a conductive wire disposed about its perimeter. |
