Definitions

  • Device for determining an object in particular locating device or material recognition device
  • the locating device is initially held once so that the measuring range is sufficiently far away from the wall 18 or objects 14, 16 to be measured.
  • a calibration measurement can be carried out. This measurement can be started manually or automatically by the control unit when the measuring device 2 is switched on by an operator. In the illustrated embodiment, after turning on the high frequency sensor 6 for objects 14, 16 is searched. If no objects are detected, the calibration measurement is started by the control unit 10 and maintained until an object 14, 16 is detected by the control unit 10 in conjunction with the high-frequency sensor 6. Alternatively, the calibration measurement can be started by the control unit 10 after the switch-on and be maintained until the Control unit 10 in conjunction with the inductive sensor 6 detects an object. The detection can be triggered by a measuring signal which changes rapidly in time and which changes faster than a preset threshold change.
  • the fuzzy network is the logic 44 to the high-frequency evaluation unit 46 and the input means 48. In this way, an evaluation result from the high-frequency evaluation unit with the measured phase angle 50 in the fuzzy network can be processed to a unique result of geometric information. If, for example, the phase angle lies in the region around 50 ° and if the result from the high-frequency evaluation unit is that the detected object is, with high probability, an iron object, then the geometric information of a pipe can be output.
