As part of Plant Integrity Ltd's continuous drive for improvement of its flagship Teletest Focus+ Guided Wave inspection product, the system has now gone WiFi. The WiFi-enabled Teletest units have been used successfully on site with a range of up to 50m between the laptop and the electronics, giving a significant benefit to the equipment operator.
The original Teletest Focus+ unit development was a two-year undertaking between Plant Integrity, key industrial partners, and TWI's Long Range Ultrasonics Group, providing a pulser-receiver unit that not only improves guided wave inspection for site technicians but also provides the optimum platform for guided wave research and development for TWI and other institutes. This has proved invaluable for research projects such as Tank Integrity Monitoring, now permanently installed on pipelines and other condition monitoring projects.
The Teletest Focus+ pulser-receiver unit still has ethernet communication back-up, 24 fully independent transmit-and-receive channels for quick data collection. Better range and sensitivity has been achieved due to maintaining the Teletest standard output voltage of 300V peak-to-peak with improved sampling resolution and filtering.
Key features introduced in the previous electronics unit, such as the internal electric pump for inflation of collars and GPS, have proved so popular that they have been kept within the new unit. Inspection of pipelines is still operated in octants to fully utilise the A-Map (unrolled pipe) and secondary focusing technique unique to Teletest.
This additional functionality has not compromised the weight of the electronics, with a 45% reduction over the previous versions and only 8kg.
The Teletest Focus+ system is fully back-compatible with tooling and Teletest WaveScan software. Teletest operates in Multimode configuration as standard, uniquely providing longitudinal and torsional wavemode inspection simultaneously. In addition, a new five ring torsional module has been launched that provides a high amplitude, broad-frequency range torsional inspection when additional power is required, without the need to change transducer spacing.
