เครื่องวัดความสั่นสะเทือน FLUKE 805
Vibration Meter
Features and Benefits
Innovative sensor design helps minimize measurement variations caused by device angle or contact pressure
Consistent data quality at both low and high frequency ranges
Four-level scale indicates severity of problems for overall vibration and bearing condition
Exportable data via USB
Trending in Microsoft® Excel using built-in templates
Overall vibration measurement (10 Hz to 1,000 Hz) for acceleration, velocity and displacement units of measurement for a wide variety of machines
Crest Factor+ provides reliable bearing assessment using direct sensor tip measurements between 4,000 Hz and 20,000 Hz
Colored lighting system (green, red) and on-screen comments indicate how much pressure needs to be applied to take measurements
Temperature measurement with Infrared Temperature Sensor increases diagnostic capabilities
On-board memory holds up to 3,500 measurements
Audio output for listening to bearing tones directly
External accelerometer support for hard to reach locations
Flashlight for viewing measurement locations in dark areas
Large screen with high resolution for easy navigation and viewing
