FLUKE 805 Oscillator

FLUKE ? FLUKE 805 Vibration Testers Fluke 805 Vibration Tester ▒ Product Overview An accurate and reliable method of measuring bearings and overall vibrations. Decide with confidence whether or not to perform maintenance tasks. The Fluke 805 vibrometer is the most trustworthy vibration screening device for field mechanical problem solving teams that need to measure the severity of overall vibration and bearing conditions in a reproducible manner. Features of 805 • Not only the overall vibration but also specific variables such as bearing conditions and temperature are measured through the meter, not through the pen to provide more complete data. • Combination vibration and force sensor tips to correct user-induced changes (force or angle) provide accurate repeatable readings. • Use four levels of scale and text notifications (good, satisfied, dissatisfied, not acceptable) that can be easily identified by the onboard processor to measure the bearing • situation and overall vibration. • A wide range of sensor sensitivity is provided to read a wide range of frequencies (10 Hz to 1,000 Hz, 4,000 Hz to 20,000 Hz) covering most machines and elements. • The user interface is simple, minimizing what you enter for RPM ranges and equipment types. ▒ Key features • Innovative sensor design minimizes measured vibrations caused by device angle or contact pressure • Provides constant data quality in both low and high frequency ranges • Show overall vibration and bearing severity through four levels of scale • Can export data via USB • Trending in Microsoft® Excel with built-in templates, acceleration for various machines, Overall vibration measurements (10Hz to 1,000Hz) in units of velocity and displacement measurements • Crest Factor+ that uses direct sensor tip measurements (4,000Hz to 20,000Hz) to provide stable bearing evaluation. • Color lighting systems (green, red) and screen descriptions showing pressure that must be applied to measure • Temperature measurements through infrared temperature sensors improve diagnostic capabilities • Up to 3 in onboard memory,500 measurements can be stored • Audio output for direct bearing tones • External accelerometer to support measurements for hard-to-reach locations • Flash for easy navigation and verification of measurement locations in the dark • High-resolution large screen 805 allows you to view the following machine categories. • Cooler (refrigerator) • Fan • Cooling tower drive • Centrifugal pump • Positive displacement pump • Air compressor • Blender • Regular gearbox (rolling element bearing) • Mechanical tools (motors, gearboxes, spindles, etc.) What is the Crest Factor+? Crest Factor+ is a new proprietary algorithm/technology that can clearly evaluate bearings. The Crest Factor was originally used for vibration analysis for the purpose of identifying bearing faults. This is defined as the peak value of the time domain vibration signal divided by the RMS. The original Crest Factor did not increase linearly as the bearing deteriorated, so there was an important limitation that it was very difficult to determine the severity of the mechanical problem. Indeed, the wave height rate may decrease with large RMS values and severe bearing failure.To overcome this limitation, Fluke uses a proprietary algorithm known as Crest Factor+ (CF+). CF+ values range from 1 to 16. The worse the bearing situation, the higher the CF+ value, which makes it easier for the user to determine the severity of the problem. In addition, Fluke included four-step severity scales: Good, Satisfied, Dissatisfied, or Unacceptable to provide a simpler identification of the problem. Export to 805 and Trending The most efficient way to track machine status is to trend (repeated vibration measurements kept in spreadsheets for a period of time). 805 makes it easy to do the following.• Connect USB and export results to Excel • Trend readings using embedded Microsoft® Excel templates and plot graphs • Compare full vibration readings to ISO standards (10816-1, 10816-3, 10816-7)
