	(Rapid Motion Scanner)
	A high speed, Ultrasonic C-scan imaging system scanning at 730mm per second with a 2mm resolution

Silverwing UK Ltd are pleased to present the latest addition to their range of corrosion detection and sizing systems the RMS 600, 450P and 300.

The RMS is a remote access Ultrasonic C-scan imaging system. Utilising a combination ultrasonic pulser/receiver with a built in high speed A/D converter, sampling at 50MHz, the RMS is capable of operating at a scanning speed of 730 mm per second. The control software has been written especially for the latest generation dual core notebooks which fully utilises the Microsoft Vista operating platform.

The data acquisition, analysis and reporting software comes as a combined suite and automatically stores the A-scan, C-scan image and thickness measurement whilst scanning at 730 mm per second with a maximum resolution of 2 mm x 2 mm.

The RMS 600 comes with a remote access crawler supporting a 600mm wide scanning bridge as standard. A second crawler with a 300 mm wide scanning bridge is available for inspection of areas with obstacles such as nozzles that prevent access using the wider bridge. Ultrasonic data is captured via a single crystal immersion transducer. The transducer is mounted in a fully gimballed probe holder, which ensures it remains perpendicular to the surface. A stainless steel wear plate prevents transducer damage when scanning over rough surfaces.

The two low profile tractor units utilise high torque stepper motors combined with magnetic drive wheels. The combined magnetic pull is in excess of 100Kg, which is 5 times the unit weight of 20Kg, ensuring that it remains attached to the structure no matter what angle it is driven at.

A 110v water pump is supplied as part of the system and a 15metre combination umbilical cable is used for data transfer, control instructions and couplant supply. For taller structures or large diameter vessels there is an option to purchase a 30m umbilical cable.
