MORE than half of unplanned downtime is attributed to mechanical failures. Vibration testing provides a way to determine where a machine is on the failure curve allowing maintenance teams to react as needed. The higher the overall vibration of a machine the worse the condition is.

That’s according to Comtest which is offering the Fluke 805 vibration meter that measures overall vibration, bearing vibration and temperature simultaneously. “Bearing condition is assessed automatically with use of Crest Factor Plus (CF+) and temperature is often used as a second opinion that confirms the bearing assessment based on vibrations,” the company said in a statement.

“With Fluke Connect for the FC enabled models, or a free excel template trend plots on all available parameters are easily created."

Overall vibration values are used to create trend plots that help to predict the condition of a machine and to plan maintenance. Machine condition of most common machinery can be determined instantly with alarm levels that are programmed in the product.

“Users such as frontline mechanical troubleshooting teams and machine operators of high-end process facilities (petrochemical, pulp and paper, primary metals, utilities, food, product, etc.) are very specific about inconsistencies in results when using vibration screening devices.

“Fluke 805 promises reliable, repeatable results thanks to the innovative sensor and sensor tip design that minimizes measurement variations caused by angle or pressure. This unique sensor force design compensates for the pressure applied during measurement, and provides reliable results both for overall vibration (10 Hz to 1,000 Hz) and bearing measurements (4,000 Hz to 20,000 Hz).”

The Fluke 805 Vibration Meter provides a four level severity scale (Good, Satisfactory,Unsatisfactory and Unacceptable) for both overall vibration and bearing condition. Rather than seeing unexplained lights or numerical indications, users can easily assess the severity of the situation with text-based alerts.

The device can hold up to 3500 measurements and if long term trending is required, users can easily export data through a USB connection. No special software is needed because the product is shipped with a disk containing pre-built Excel templates.
