  • Kokapen zehatza: Features two detection modes:
    • General Mode: For rapid investigation of large areas.
    • Location Mode: Provides accuracy within 10cm for precise identification of leakage points.
  • Dual-Diaphragm Resonance Technology: Enables precise acquisition of weak signals, even in narrow and confined spaces. This technology ensures synchronous resonance when leak sound waves reach the sensor, amplifying the vibration amplitude for accurate detection.

    Dual Membrane Resonance Sensor Working Principle

5. Konfigurazioa eta funtzionamendua

5.1 Hasierako konfigurazioa

  1. Gailua kargatu: Connect the host machine to the charger using the USB data cable. Ensure the device is fully charged before first use.
  2. Konektatu osagaiak: Attach the desired sensor (DMR-H40, DMR-V59, or RCS-S3) to the host machine. Connect the control handle and headphones.
  3. Piztu: Press and hold the power button on the host machine to turn it on.

5.2 Funtzionamendu moduak

The PQ125C offers two primary detection modes:

  • Modu orokorra: Use this mode for initial surveys and rapid investigation of large areas to quickly identify potential leak zones.
  • Kokapen modua: Once a potential leak zone is identified, switch to Location Mode for precise pinpointing of the leak. This mode provides accuracy within 10cm.

5.3 Leak Detection Procedure

  1. Hautatu sentsorea: Choose the appropriate sensor based on the detection environment (e.g., DMR-H40 for walls, DMR-V59 for indoor floors, RCS-S3 for outdoor ground).
  2. Initial Scan (General Mode):
    • Place the sensor on the surface above the suspected pipeline.
    • Move the sensor along the direction of the pipeline.
    • Monitor the sound and image fluctuations on the display. Areas with small fluctuations indicate no damage.
  3. Pinpointing the Leak (Location Mode):
    • When significant sound and image fluctuations are observed, indicating a potential leak, switch to Location Mode.
    • Carefully move the sensor in smaller increments around the area of high fluctuation.
    • The device will provide a clear indication of the leak's precise location.
