Bearing Sensor Case Style Features: For embedded applications in rotating machines RTDs - 100 ohm platinum, 0.00385 ohm/ohm/°C Thermocouples types J, K, T & E Single and duplex sensors Various styles and sizes Operating Temperature: to +250° F (+120° C) Bearing Sensor Optional Spring and Star Washer The spring and star washer are options for the TOP HAT case style B sensor. The top hat shape allows spring loading by use of a spring and retaining ring clip. The sensor tip is inserted into the milled hole, then the retaining ring clip is pushed down to compress the spring and retain the sensor. Using these sensors will give reliable indication as to the bearing condition. This may provide an early warning of oil film breakdown and allow the machine to shutdown and avoid unnecessary damage.
