雷竞技appThe LED strobe Fluke 820-2
The main features
- High brightness 7 - LED array - 4800 Lux @ 6000 FPM / 30 cm
- Unified scintillation characteristics of high efficiency LED solid-state light source, can achieve higher flicker frequency - 30-300000 FPM (flashing number per minute)
- Digital pulse width modulation, can high speed rendering extremely clear image
- No filament, gases, rugged design using hollow fiber or glass solid-state leds can bear (1 m drop)
- Quartz accuracy control system provides high accuracy - 0.02% (+ / - 1)
- Multi-channel LCD display
- Check the machine without physical contact or reflective tape speed
- Increasing or reducing flicker time, in order to check the gear teeth, the number of shear plane, repetitions, or "drift" equipment
- Simple button operation, equipped with 2 x and present 2 buttons, easy to adjust
Adjustable flash duration
Standard flash duration suitable for most applications, without having to adjust.In other applications (high RPM or faster on the surface of the larger rotating object), you need to use the flash duration can be adjusted.Under the high speed applications, the object may move in a twinkle in a short period of time, the image is not clear.Shorten the duration of scintillation, the movement of the object will be cut short, display image is clear.
The common application of 820-2
雷竞技appFluke 820-2 LED strobe without physical contact is not only a kind of measuring mechanical equipment rotating speed of the tool.Or is suitable for various applications of excellent diagnostic tools:
- Belt drive machines - HVAC fan and pump
- Ball bearings, shaft, gear and other machine components
- The clutch and gear
- The foundation - resonance
- Cable or pipe worn or damaged
- Mixing and dose process

Safely observation and study of potential mechanical failures
Rotating equipment雷竞技app running speed measurement is not easy, but the Fluke 820-2 LED strobe simplify the process, don't need to actual downtime, execution stops without contact sports equipment diagnosis.Whether to diagnosis of parasitic oscillation and slip or harmful deformation, 820-2 LED strobe is the ideal site trouble shooting, process or product research and development tools.
The LED strobe can also be used as a measure speed stroboscopic tachometer, without using laser tachometer.Is measured using the strobe, the parts must be visible, and can be used as a reference point identification tags.Stroboscopic tachometer is a very useful tool, because you can't always by contact machine shaft to paste the reflective tape, to use the laser tachometer, or moving axis by using contact type tachometer - through the use of stroboscopic, you can lower the shaft speed and to 30 "frame" RPM (FPM).
820-2 is applicable to:
- Turbine with variable speed and speed change often
- With variable speed but rarely change the variable frequency drive motor
- Check the belt speed and find the belt slip
- Check the machine components -- fan blade, pump, compressor, screw and gear tooth.
- The RPM measurement and frequency of inspection
- Slip measurement
