The Fluke 820-2 LED Stroboscope is used for performing extensive stop-motion diagnostics on rotating machinery without the need to make direct contact.
With the Fluke 820-2, you'll be able to easily determine parasitic oscillations, slippage and unwanted distortions, making this stroboscope highly useful for a wide variety of applications including belt-driven machines, roller bearings, shafts, gear teeth, other machinery components, clutches and cogwheels, foundations (resonance vibration), cable/piping wear and damage and much more.
Stroboscopes are much more efficient than standard laser tachometers; by using a strobe system you don't need to make a mark on the system you're testing to measure. Instead, the stroboscope gives the illusion of 'stopping' the rotating of the machinery, allowing measurements down to 30RPM (FPM) and higher.
The Fluke 820-2 caters for practically any application thanks to its adjustable flash duration. This is ideally suited for applications with higher RPM or larger, rotating objects with high surface speeds. Reducing the flash period increases the image quality, ensuring measurements are as accurate as possible.
