Advanced Ultrasonic Thickness Gauge for Industrial UAVs
No surface preparation or couplant
Robust thickness measurements
Lightweight Compact & Modular
No force required from UAV to take measurements

DroneMAT is a electromagnetic acoustic transducer (EMAT) ultrasonic thickness (UT) gauge designed for industrial UAVs (Drones). It allows users to perform ultrasonic thickness inspections from drones in a more efficient, reliable and safer way. The modular and lightweight design allows conversion of any industrial drone to an aerial UT gauge, increasing the range of applications and utilization.

DroneMAT on corroded surface
  • Decrease cost of inspection vs the conventional way by increasing inspection speed and elimination of auxiliary equipment

  • Eliminate working at height by inspectors and reduce potential risks

DroneMAT Silo Inside Contact
  • Modular design allowing integration to any industrial drone (total payload < 700 gr)

  • Allows inspection on any metal surface - coated, unbonded paint or corroded

DroneMAT Matrice Approach 3
  • Independent sensor aligning to measurement surface

  • No contact required to perform measurements  - gap up to 3 mm / misalignment (angle) 25 degrees

  • Measurement immune to drone noise

  • User friendly App with easy data management  (including A-Scan and Inspection details)

EMAT Technology

EMAT technology allows significant advantages over standard piezoelectric thickness gauges in applications for drone inspections:

  • No paint removal required (non-contact up to 3 mm)

  • No surface preparation

  • No couplant required

  • Measures through unbonded paint

  • Sensor not required to be perpendicular to test material

  • Use in corroded areas

  • High temperature applications
