INDUSTRIAL RTD MINIATURE BEARING TEMPERATURE SENSORS New Product Design The bearings of industrial rotating equipment operate under arduous conditions ­ often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the shoe. Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film, allowing machine shutdown and maintenance to take place before catastrophic failure of the bearing and possible damage to its mounting. Conax Miniature Bearing sensors provide a simple and cost-effective method to monitor bearing temperatures.
