spotOn® AE

Acoustic Emission (AE) is the most flexible NDT method.

Normally used for screening of large structures,

A³ Monitoring utilises spotOn AE for monitoring of structures.


spotOn AE can be used for monitoring the ‘acoustic activity' generated while hitting the pipe.

Accidental (digger hitting pipe) third party interference is detected using spotOn AE and appropriate alarm is sent to the asset owner or pipeline operator.

spotOn® CP

spotOn CP identifies external threats with sudden  change of voltage due to coating damages.


spotOn CP checks voltage and alarm is sent immediately if a value exceeds a user threshold. This communicates using mobile, satellite or wifi comms. Data is automatically stored and can be accessed at any time via Internet.

spotOn® AE+ CP

Combination of

spotOn AE

(Acoustic Emission)


spotOn CP

(Cathodic Protection)


has been developed as a  specialist product to detect  third-party damage along petrochemical pipelines.


AE identifies events generated while mechanically interfering with the pipeline.


CP recognises anomalous variations in voltage caused by breakages in coating.
