Fluke 820-2 LED StroboscopeInvestigate and observe potential mechanism failure with confidenceIdentifying the running speed of rotating equipment can be difficult, but the Fluke 820-2 LED Stroboscope simplifies the process allowing you to perform stop motion diagnostics without actually stopping, or making contact, with the machine you are working on. Whether you are trying to diagnose parasitic oscillations, slippage, or unwanted distortions, the 820-2 LED Stroboscope is the ideal frontline troubleshooting, process or product research and development tool.High-intensity 7-LED array � 4,800 Lux @ 6,000 FPM/30cmHigh efficiency LED solid-state light source with uniform flash characteristics allows for higher flash rates � 30-300,000 FPM (flashes per minute)Digital pulse width modulation for exceptionally sharp images at high speedsRugged, durable design utilizes solid-state LEDs with no filaments, gases, hollow cavities, or glass � (1 meter drop)Quartz-accuracy control system provides high accuracy � 0.02% (+/- 1 digit)Multi-line LCD displayCheck the rotating speed of machinery without physical contact or need for reflective tapeAdvance or retard flash timing for viewing gear teeth, cutting surfaces, repeats, or drifting equipmentSimple push button operation with 2x and �2 buttons for easy adjustmentAdjustable flash durationFor 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 820-2The 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, pumpsRoller bearings, shafts, gear teeth or other machine componentsClutches and cogwheelsFoundations - resonance vibrationsCable or piping wear or damageMixing and dosage processesIn addition, the LED 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).Use the 820-2 for:Turbines that vary in speed and change speed frequentlyVariable Frequency Drive motors that vary in speed, but do not change frequentlyFind belt rotation speed and look for belt slippageFind machine element components � fan blades, pump vanes, compressor screws, and gear teethRPM measurement and frequency investigationSlip measurement820-2 LED Stroboscope Includes:Protective caseExternal trigger connector
