Olympus NDT, a specialist in non- destructive testing (NDT) instruments and solutions, offers customers a wide range of manual or automated inspection solutions featuring innovative ultrasonic testing (UT), eddy current (ET), and related non-destructive testing technologies. Non-destructive testing is a means for examining thehidden internal structureor measuring the thickness of parts without cutting or otherwise damaging them. It offers important tools for ensuring both safety and quality control in a wide

Olympus NDT recently introduced the new Epoch LTC digital ultrasonic flaw detector. Weighing only 2.12lb (0.96kg), the handheld instrument is now the smallest in its line of Epoch flaw detectors. The rugged Epoch LTC is built for use in a wide range of weather conditions and difficult inspection environments. Its sealed case meets IP67 requirements to withstand the rigours of very wet or dusty environments, while the multi- As leaks along pipelines have severe environmental and safety implications, integrity of supply has never been more important. Conventional monitoring techniques are unable to offer real-time, continuous, non-intrusive monitoring. Sensornet’s digital pipeline leak detection solution uses fibre optic Distributed Temperature Sensing (DTS) technology to spot and locate the smallest leak in seconds, and to within 1 metre, without operational delay or risk.

Olympus NDT’s Epoch LTC digital S S ultrasonic flaw detector

The Epoch LTC provides powerful standard measurement features and specialised software options to find internal defects in a variety of materials. The instrument is EN 12668-1 compliant and features a square wave pulser, selectable digital filtering, gain range from 1 to 110 dB, peak memory, 0.001" (0.01mm) measurement resolution, and one gate with programmable alarm. Dynamic DAC/TVG software is standard with the Epoch LTC, and application- specific software options include DGS/ AVG flaw sizing, manual PRF control, extended range, tunable square wave pulser, curved surface correction, and AWS D1.1/D1.5. The Epoch LTC provides internal storage of inspection data of 50,000 IDs with waveform and measurement parameters, while a Mini

The Sentinel Distributed Temperature S S Sensing system is part of Sensornet’s digital pipeline leak detection solution

The system is an extremely versatile leak detection solution that is based on temperature measurements using distributed fibre optic sensing technology. It can be used to detect both liquid and gaseous leaks in diverse industrial applications such as oil and gas transmission and distribution; LNG, steam and water pipelines. The system can be used along long distance pipelines with repeater stations situated at block valve or pumping stations, providing full coverage of the entire pipeline. By detecting the temperature change of the surroundings, the DTS can not only detect the presence of a leak, but can also pinpoint the location of the leak down to 1m. The system provides measurements from every 10 seconds, as such rapid detection is essential in the case of potentially explosive gases. Distributed Temperature Sensing is the only leak detection technique that can monitor the pipeline in real time and provide precise leak location to the nearest metre. Sensornet offers a complete monitoring solution package, including initial application design input, system installation and integration, commissioning and data interpretation. The company works with advanced thermal modelling software and leading industry partners to monitor mission critical infrastructure and obtain meaningful and valuable information.
