Abstract

A detector 5 for detecting a buried conductor 7 comprises a plurality of antennas B, T. Each antenna B, T has a winding 29 wound around the antenna, the winding 29 being connected to a current source 31 for providing a predefined current in the winding 29. When the predefined current is applied to the winding 29 an electromagnetic field is generated at the antenna which induces a test current in the antenna. The test current is compared to calibration data stored in the detector 5 to validate the correct operation of the detector 5.

Abstract

A detector for detecting a buried current carrying conductor includes a digital signal processor, magnetic sensors, and a power supply unit. The power supply unit is a switched mode power supply which incorporates a proportional integral differential controller feedback algorithm and which is managed by the digital signal processor. The load and source voltage are monitored by the digital signal processor and a look-up table is used to control a pulse width modulator, which drives a single ended primary induction controller. The digital signal processor processes and compares signals received from the sensors to calculate a depth of a buried conductor. The self-generated noise of the power supply unit does not interfere with the frequency bands of detection of the detector.

Abstract

A radio mode selectivity block 41 for a detector 1 for detecting a buried current carrying conductor comprises a plurality of beat frequency oscillators 53 to center the bandwidth of detection of the detector 1 on target very low frequency (VLF) frequency bands. The frequencies of the beat frequency oscillators are chosen to fall within the VLF frequency bands used in a number of countries, so that the detector 1 can be used in radio mode in these countries without the need for local configuration.
