Efficient magnetic two probe TOFD (time-of-flight diffraction) handheld scanner

The MICROBE – 2 Probe TOFD Scanner is a small handheld device with built-in encoder and magnetic wheels. It is designed to translate two TOFD probes around ferrous piping and vessels.


Component Identification

The MICROBE Cart contains the built-in positional encoder while the removable handle allows for cable management and access to the umbilical.

Various lengths of frame bars, to which the probe holders and accessories mount, are available.

The versatile slip joint probe holder carries the phased array probe and wedge with seemingly endless adjustment possibilities.

The magnetic wheels maintain scanner contact with the inspection surface. Add additional magnetic wheels to double the magnetic attraction.

A brake prevents the MICROBE from unwanted rolling on a scan surface.

A vital component to the MICROBE, the umbilical housing is a plug-in for optional y-axis accessories. As well, the umbilical exports encoder signals to the user’s instrument and acts as a means of cable management.
