PATENTED CONTACT-LESS LPS INSPECTION

Conventional LPS inspection tells you something is wrong. TOPseven BEAT tells you where. A tuned 13.565 MHz signal injected into the down conductor. A drone-mounted Field Sensor reading the emitted field along the blade. Fault location identified without opening the circuit.

Resistance Measurements Confirm a Problem. TOPseven BEAT Finds It.

A failed continuity test tells you the conductor path is broken. It does not tell you where. That uncertainty means either a full rope-access inspection or a repair decision made without precise information. BEAT changes that. A tuned AC signal is injected into the LPS down conductor. The Field Sensor reads the near field along the blade during flight. Discontinuities appear as measurable changes in the standing wave — localized, documented, and ready for review without a single contact point on the conductor.

Three Components. One Inspection Sequence.

Three Components. One Inspection Sequence.

BEAT is designed around a single operational logic: mount, calibrate, fly, measure, review. Three Signal Generators inject the test signal at the blade roots. The drone-mounted Field Sensor handles calibration, measurement, and communication during flight. The onboard calibration camera eliminates the need for a separate calibration flight — reducing setup time and getting teams into the inspection sooner.

Non-invasive by design

The induction coil injects the test signal without cutting the cable, disconnecting the conductor from ground, or physically altering the LPS installation. The circuit stays intact throughout.

One less flight

The onboard calibration camera is integrated directly into the Field Sensor. No separate calibration flight required. Less setup, fewer flight hours, and a simpler workflow from arrival to measurement.

Built on a shared platform

BEAT shares the same compute architecture, software stack, and sensing approach as the TOPseven sensor platform. Tighter integration today. More capability as the platform develops.

No cable cuts. No intervention.

The Signal Generator injects the measurement signal non-invasively. The conductor is never cut, disconnected, or physically altered during inspection.

Localize. Not just detect.

BEAT identifies where the fault is, not only that one exists. That is the difference between a targeted repair and a full access inspection.

    Blade by blade. Automatically.

    Thanks to new onboard calibration the drone flies the inspection path automatically. The Field Sensor commands each Signal Generator in sequence, measures the emitted field, and the drone lands automatically at the end of the mission.

    The standing wave. Measured precisely.

    BEAT measures the standing wave created along the rotor blade when a 13.565 MHz signal is injected into the down conductor. Changes in amplitude and the position of minima indicate impedance changes in the conductor path. If the conductor is completely disconnected, the near field beyond the fault no longer appears — allowing the interruption to be localized with precision rather than inferred from a single pass-fail result.
