Comtest has introduced the Fluke 805 vibration meter, a portable multifunction vibration screening tool that provides quantifiable information on a bearing and the overall health of motors and other rotating equipment. The Fluke 805 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, currently on the market, provide an overall number for vibration condition and some also provide an overall number for bearing condition. Fluke’s design engineers produced the 805 vibration meter to provide quantifiable results of bearing condition, overall vibration and temperature, assesses condition severity using text-based alerts, and exports and trends data using built-in templates. It is an accurate and user-friendly tool that improves day-to-day machine checks, so users can keep their facilities and plants up and running.
The instrument measures:
• Overall vibration from 10 to 1000 Hz, providing a four-level severity assessment for overall vibration and bearing condition.
• Identifies bearing condition (CF+) by detecting peaks in the vibration signal readings of roller bearings from 4000 to 20 000 Hz, and using a proprietary algorithm 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 Fluke 805 handheld vibration 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 readings, delivering more information than comparable vibration pens. Logged data can be easily uploaded into Excel to create trending reports.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.
