Q. We want to measure bearing temperature in our motors to alert us of overheating. We have used a type of sensor which inserts into the side of the motor, but they leak and fail often. We would like to put something on the surface of the motor outside of the bearing housing, but we do not want something welded to the housing. What can you suggest?

A. The best solution for your application is a WORM sensor with a Magnetic Pad (-MPAD). The -MPAD has 40lbs of attraction and will hold up to a vibrating surface. We also suggest adding our 30G option to the RTD, in order to protect the RTD element inside the sheath from high vibration during motor operation. Standard fixed length sensors cannot withstand this vibration over time. The -MPAD with WORM sensor is easy to install on any ferrous metal surface.
