Bearing RTDs are designed for areas where there are space limitations. They are small, compact and are often used to detect temperature increases in bearings, thrust bearing plates, shafts and motor windings. They are miniature low mass sensors which are fast responding.

Bearing sensors are manufactured using thin film technology and by design are tip sensitive and vibration resistant. They can be spring loaded into a bearing housing or held in position with a high temperature epoxy resin.
