Completing a UXO survey does not mean the work is finished. Proper inspection and maintenance of magnetometer equipment after field operations are essential for identifying wear, preventing unexpected failures and preparing for the next project.

Inspecting the magnetometer module

After demanding fieldwork, the magnetometer module should be carefully inspected for signs of wear or damage.

The non-magnetic steel housing helps minimise interference with magnetic measurements. However, this material is less wear-resistant than tempered steel, making it important to check for excessive wear, dents or deformation.

The tip, threaded connections, connector pins and sounding cable should also be examined for damage, contamination and wear. Even when a cable appears to be in good condition, weakened connections can introduce noise or interruptions into the measurement data.

Checking measurement quality

Equipment inspection goes beyond visible components. Reviewing the final measurement data can help identify potential issues within the measurement system.

Unexpected drift, increased noise or inconsistent readings may indicate that the sensor or another component requires further inspection.

A post-project check should also confirm that the magnetometer module, cabling, CPT-Logger, depth synchronisation and software continue to function together correctly.

Following an impact, overload, repair or questionable measurement results, additional inspection or calibration may be necessary before the equipment is used again.

Designed for easier maintenance

Gouda UXO-Equipment has designed the exterior housing components of its magnetometer module to be replaceable by operators without dismantling the measuring unit itself.

This allows worn or damaged exterior parts to be replaced more efficiently, helping to reduce downtime and avoid unnecessary shipping, additional equipment requirements and import/export handling.

Ready for the next project

Regular inspection and appropriate maintenance help identify potential problems before they affect field operations.

By checking both the physical condition of the equipment and the quality of the measurement data, operators can prepare their magnetometer systems for reliable performance on the next UXO investigation.
