Method of measuring crack depths in electrically conductive metal workpieces using current probes with voltage probes located between current probes by measuring the minimum potential difference between the voltage and current probes
专利汇可以提供Method of measuring crack depths in electrically conductive metal workpieces using current probes with voltage probes located between current probes by measuring the minimum potential difference between the voltage and current probes专利检索，专利查询，专利分析的服务。并且A method for determining in a nondestructive manner the existence, the depth and the length of cracks in an electrically conductive metal workpiece such as a steel plate or a steel pipe, by means of an electric resistance measurement which is carried out by using a pair of current probes and a pair of voltage probes located between the current probes, and, if a defect is located between the current probes and the voltage probes, the measurement is made on the basis of the minimum potential difference detected by the voltage probes rather than by the maximum value in the measured voltage distribution.，下面是Method of measuring crack depths in electrically conductive metal workpieces using current probes with voltage probes located between current probes by measuring the minimum potential difference between the voltage and current probes专利的具体信息内容。
