The Fluke 805 vibration meter is a portable multifunction vibration screening tool that provides quantifiable information on a bearing and the overall health of motors and other rotating equipment. It is ideal for frontline mechanical troubleshooting teams that need reliable and repeatable measurements of rotating equipment to make imperative go/no-go maintenance decisions.
Most vibration pens and other screening devices provide an overall number for vibration condition and some also provide an overall number for bearing condition. However, Fluke’s design engineers produced the 805 to provide quantifiable results of bearing condition, overall vibration and temperature, assess condition severity using text-based alerts, and export and trend data using built-in templates. It is an accurate and user-friendly tool that improves machine checks so operators can keep their facilities running optimally.
The Fluke 805 measures:
• Overall vibration from 10 to 1000 Hz, providing a four-level severity assessment for overall vibration and bearing condition.
• Bearing condition (Crest factor Plus, CF+) by detecting peaks in the vibration signal readings of roller bearings from 4000 to 20 000 Hz, and using a proprietary algorithm to interpret severity, to determine if the bearing is going bad.
• Surface temperature using an infrared sensor which automatically measures contact temperature and displays it along with the vibration reading for a broader understanding of machine health.
The meter has a unique sensor tip design that minimises measurement variations caused by device angle or contact pressure. This reduces operator error and improves the accuracy and repeatability of quick vibration screening. The meter also provides a severity scale for both overall vibration and bearing condition, delivering more information than many comparable vibration pens. Logged data can be easily uploaded into Excel to create trending reports.
