● No expensive scaffolding, no backbreaking surface preparation! Best of all, no water, no couplant and no mess!
● The EMAT (Electromagnetic Acoustic Transducer) thickness measurement robot is a flexible and versatile tool for corrosion/erosion inspectionon ferromagnetic equipment such as pipes, vessels, tanks in power generation, refining, petrochemical and other industries. The integrated EMAT sensor can tolerate paint, coating, and rough surface.
● With the strong magnetic wheels, the robot can climb up 25 meters (82 feet) above the ground. Operator can control the robot remotely through a hand-hold controller or a touch-screen industrial-grade tablet while monitoring the robot surrounding from the front and rear cameras.
1 Key Product Features
No expensive scaffolding. Equipped with two high strength magneticwheels, the crawler can climb up 25 meters (82 feet) above the ground. Front and rear cameras provide live-feed video surrounding the robot to the remote operator for safe and accurate control.
No backbreaking surface preparation. The advanced EMAT sensor can tolerate paint and coating up to 4 mm (0.16”) and rough surface. Non-perpendicularity can be up to 25 degree. No need ultrasound couplant, no cleaning required after inspection.
Three thickness computation algorithm. The default auto-expert mode significantly reduces the influence of human factor and simplifies the inspection process. Two other modes, “single peak” and “peak-to-peak”, are available at the operator’s discretion.
Compact design offers high flexibility on small ferromagnetic pipe, elbow and other complex surfaces. Longitudinal scan on straight pipe or elbow: Min. diameter 100 mm (4”). Spiral scan: Min. diameter114 mm (4.5”), circumferential scan: Min. diameter 250 mm (10”).
Multi-mode operation: Quick thickness survey using hand-hold controller; Continuous line scan thickness profiling (B-scan); Programm able interval point-to-point thickness measurement.
Real time A-scan and B-scan display, large data storage and auto-reporting
