The GE / Bently Nevada TK21 Oscilloscope Interface allows most dual-channel oscilloscopes with a Z-axis input to perform diagnostics on rotating machinery. The interface receives signals from XY and Keyphasor proximity transducers and allows the oscilloscope to provide an orbit presentation from these signals.

Using the TK21 with an oscilloscope enhances machinery diagnostic capabilities by allowing the user to view vibration, position, and phase information.

The TK21 works with oscilloscopes that have a Z-axis (sometimes referred to as an external blanking) input. The oscilloscope must also have the capability to display X versus Y. The factory settings for the Keyphasor gain and offset in the TK21 ensure compatibility with most Tektronix oscilloscopes. The user can easily adjust these settings to suit any oscilloscope.

Product Family: TK21, TK-21, TK 21

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.
