The Fluke 820-2 LED Stroboscope is more than just a tool to measure rotational speed of machinery without physical contact. It is also an excellent diagnostic tool for a wide variety of applications in a vast range of industries. Even better, it’s a Fluke tool which means that it is rugged and ergonomic. It allows clear observation of machinery in motion - all cyclic motion can be slowed or stopped visually in order to note performance, observe dynamic motion, measure speed, or photograph/video the action.
The Fluke 820-2 is far superior to its competitors on every front including feature set, form factor and brand promise. The stroboscope can be used as a strobe tachometer to measure the speed instead of using a laser tachometer. In order to use the stroboscope, you will need access to visibly see the object to measure and it needs to have some marking on it to use as a reference point. A strobe tachometer is a good tool to have because you can’t always get access to the machine shaft to stick a piece of reflective tape to use a laser tachometer or make contact with the moving shaft to use a contact tachometer.
Rugged, compact and easy-to-use
Investigate and observe potential mechanism failure with confidence on a variety of machinery, in a wide range of industries, without making physical contact with the machine. The Fluke 820-2 LED Stroboscope is a rugged, compact, portable strobe ideal for stop motion diagnostics, mechanical troubleshooting, and process or product research and development.
The Fluke 820-2 LED Stroboscope is a simple, easy to use tool to stop motion for measurement and diagnostic purposes allowing you to:
Identify the running speed of rotating equipment without stopping the operation or making contact with machinery
Stop motion for diagnoses of parasitic oscillations, flaws, slippage or unwanted distortions
Measure speed of rotation or frequency of a rotating shaft, speaker, or mechanical part
Identify part numbers or other markings
Adjustable flash duration
For most applications the standard flash duration will work well without adjustment. In other applications with higher rpm or larger rotating objects with high surface speeds, an adjustable flash duration is needed. In high speed applications, objects may move during the brief period of a single flash, resulting in a blurred image. By decreasing flash duration, objects have less time to move and the image will appear sharper.
Common applications for the 820-2
The Fluke 820-2 LED Stroboscope is more than just a tool to measure rotational speed of machinery without physical contact. It is also an excellent diagnostic tool for a wide variety of applications:
- Belt driven machines-HVAC fans, pumps
- Roller bearings, shafts, gear teeth or other machine components
- Clutches and cogwheels
- Foundations-resonance vibrations
- Cable or piping wear or damage
- Mixing and dosage processes
In addition, the stroboscope can be used as a strobe tachometer to measure speed instead of using a laser tachometer. In order to use the stroboscope, the component under measure must be visible, and have an identifying mark that can be used as a point of reference. A strobe tachometer is a useful tool because you can’t always get access to the machine shaft to stick a piece of reflective tape to use a laser tachometer or make contact with the moving shaft to use a contact tachometer-using a stroboscope you can "stop" the shaft down to 30 RPM (FPM).
