Detectors are used to detect, trace and locate faults in pipelines. The detector can be used to determine the location of the camera crawler or camera head if a probe (33 kHz or 512 Hz) is used with the CamBoss or REVI system. Thanks to this, it is possible to precisely locate the detected damage and determine the next repair procedure. In addition, the detector has the ability to locate low voltage and telephone cables, which minimizes the risk of damage to these networks during excavation work.
