摘要

The experimental results of the response of a single-transmitter–single-receiver electromagnetic induction sensor to a linear conductor are reported. First, the sensor geometry is given, and a simple model is derived to predict the survey profile of the instrument as it moves over a linear conductor. Next, the experimental apparatus is described, and the acquired results are compared with those predicted by the model. As part of this analysis, various orientations of the transmitter and receiver dipoles are considered, as well as different tilt angles of the sensor head. The variation of peak signal strength with height above the linear conductor is also investigated. In all cases, excellent agreement between experiment and theory is achieved. These results demonstrate the potential for implementing simple sensors for detecting linear conductors or buried utilities and are important for verification of theoretical analyses.
