Abstract

A device for the impact excitation of concrete products and the recording of electrical responses is described. The device consists of a remote probe, a portable power supply, input/output board, and a laptop computer. A differential electrical sensor that consists of receiving measuring and compensating electrodes is used for the measurements. This makes it possible to significantly improve the signal/noise ratio. The probe is equipped with long wires that make it possible to examine different parts of extended concrete products. An example of the scanning of the surface of a concrete product and defect detection is given.
