Product Overview: Fluke 820-2 LED Stroboscope
Observe and study potential mechanical failures with confidence
Measuring the operating speed of rotating equipment is no easy task, but the Fluke 820-2 LED Stroboscope simplifies the process by allowing stop motion diagnostics to be performed without physically shutting down the equipment or making contact. Whether you're diagnosing parasitic oscillations, slippage, or harmful distortion, the 820-2 LED Stroboscope is the ideal field troubleshooting, process or product research and development tool.
The LED Stroboscope can also be used as a strobe tachometer to measure speed without the need for a laser tachometer. When using this strobe, the part being measured must be visible and have an identifying mark that can be used as a reference point. A strobe tachometer is a very useful tool because you can't always apply reflective tape by touching the machine shafts to use a laser tachometer, or touch the moving shafts to use a contact tachometer - by using a strobe you can bring the shaft speeds down and "freeze" them to 30 RPM (FPM).
820-2 Applies:
- Turbines with variable and frequently changing speeds
- Variable frequency drive motors with variable speeds but minimal speed changes
- View belt speed and find belt slip
- View machine components - fan blades, pump blades, compressor screws and gear teeth.
- RPM measurement and frequency check
- Slip measurement
