OUR TECHNOLOGY
- Built on the award winning HotSense™ ultrasonic platform powered by the proprietary Ionix HPZ piezo-ceramic, and offering increased heat resilience
- Dual element thickness gauging transducer for use through -55 to +550 °C [-67 to +1,022 °F] wide temperature range for in-service assets
- Reduce inspection time with no duty cycling or cooling up to +350 °C [662 °F] maximising productivity and minimising down-time or outages with in-service inspection
TECHNICAL DETAILS
- Measure remaining wall thickness from 1 to 500 mm with compliant thickness gauges on hot assets, in-service, without shutdown or isolation
- Better data from easier and more accurate calibration at asset temperature
- 2X increased wear resistance for the most extreme environments and applications including scanning and corrosion mapping
- Range of accessories available, including port inspection wand and safety guards for the most extreme temperatures
- Compatible with industry standard ultrasonic gauges and flaw detectors
- Compliant to EN 12668:2 and ASTM E1065 to meet existing asset integrity UT procedures
