New tool sounds' out bearinq wear

摘要

A small handheld device designed to provide an instant indication of machinery condition has been launched. The Kittiwake Holroyd MHC Bearing Checker is an acoustic emission-based instrument that can monitor an unlimited number of machines on a periodic basis. Based on the detection of the high-frequency activity generated by deterioration in rotating machinery, the device's distress parameter removes the need for machine-specific interpretations. A distress reading greater than 10 alerts the user to a problem, who can instigate further checks. A decibel level is also provided, giving an indication of the overall noise of the bearing - it increases with speed of rotation, but also with degradation of the bearing or inadequate lubrication.
