USM Go Ultrasonic Flaw Detector

The USM Go is the lightest and most portable ultrasonic flaw detector available from GE. The USM Go is designed for ease of prolonged operation in the harshest inspection environments in the oil and gas, aerospace, power generation and automotive industries.

USM Go Series/Upgradeability

The USM Go can be upgraded to include numerous features/functions. Features/functions can also be added at a later time. See USM Go Series chart below.

Productivity

The USM Go features intuitive operation so there is virtually no time-consuming, learning curve. You are productive from the moment you pick it up! Navigation is simplified using the proven graphical user interface (GUI) and the innovative joystick, allowing one-handed operation and fast and accurate adjustment. Other productivity features includes:

AutoCal

Auto 80

Gate synchronizations

Robust Construction

A robust moulded rubber casing to withstand the harshest environments and significantly reduce downtime.

IP 67 immersion test (P67 / IEC529 - dust proof / dripping water proof as per IEC 529 specification for IP67 classification)

Drop test (514.5 Procedure II; 516.5 Procedure IV)

Vibration test (Mil-Std-810F; 514.5-5 Procedure I, Annex C)

Ergonomics

The USM Go ultrasonic portable flaw detector has been ergonomically designed to provide an instrument which is light, small and easy to use in the harshest inspection environments.

Minimized housing size when used in difficult-to-access areas

Optimized display size to improve readability and echo separation

One hand operation for security

Light weight (850 g/1.87 lb)

Integrated stand

Can be used with regular camera and industrial tripods

Main controls are under the thumb: gain, free defined keys

A “Flip” function allows the instrument to be used equally well by left-handed and right-handed people.

Connectivity

A standard USB connection to allow data to be downloaded from the flaw detector for further analysis or storage. The instrument is standard delivered with a 2 GB SD memory card (can accomodate up to 16GB card size).

Reports are produced in jpeg or bmp format so there is no need for special reading software.

A simple on-board data logger to collect and save thickness measurements.

UT Detectability

Unique patented Phantom echo indicator option: wrap around echoes due to low attenuation and PRF will flash on the screen.
