Bearing Sensor Overview- Bearing sensors are miniature sensors installed in or beneath the babbitt layer of the bearing shoe. The sensors monitor the metal temperature- the most reliable indicator of bearing condition- to give early warning of oil film breakdown. Machines can then be shut down and the problem can be corrected before catastrophic bearing failure occurs.
While no larger than many bare ceramic elements, these rtds have a metal cases and insulated leads to withstand rough handling and harsh environments. They're east to install in drilled holes for general purpose sensing. A bearing failure will not only mean a application shutdown; it could also result in secondary or peripheral damage to costly internal parts. Early detection of a bearing failure may only result in an outage lasting a few days, but an undetected failure, causing major internal damage, can force an outage for weeks or months.
Most bearing failures such as flaking and pitting, spalling, unusual wear patterns, rust and corrosion, creeping, skewing and others are usually attributed to a relatively small group of causes that are often interrelated and correctable. These causes include lubrication, mounting, operational stress and bearing selection and environmental influence.
