Title: DEVICE AND METHOD FOR DETECTING ELECTRICALLY CONDUCTIVE MEASUREMENT OBJECTS IN A SUBSTRATE
Abstract:
The invention relates to a device (10) for detecting electrically conductive measurement objects in a substrate, the device comprising: a housing (21); a magnetic coil unit (34) which is located in the housing (21) and has an emitter coil unit (38) and a receiver coil unit (39); a control unit (36); and an evaluation unit (37). A metal sheet (35) is provided in the housing (21), wherein the magnetic coil unit (34) is mounted on a lower side (53) of the metal sheet (35) facing the substrate during the measurement operation, and the control unit (36) is mounted on an upper side (54) of the metal sheet (35) facing away from the substrate during the measurement operation.
