PRODUCT DATASHEET WDB83x SeriesBearing Temperature SensorsAPPLICATION For use on any application where bearing temperature monitoring is desired or required. METHOD OF OPERATION The WDB83x series is a range of contact bearing sensors manufactured to screw directly into a bearing housing. Each sensor is fitted with a grease nipple to allow lubrication of the bearing without the need for removal of the sensor. The sensor now has a fixed cable rather than the detachable Ml 2 connector which will be ready for connection either directly to a PLC or to a hazard monitoring system, such as 4B’s IE-NODE, Watchdog Super Elite, or T400 / T400 NTC Elite. The connections are not polarity sensitive therefore special connection requirements are eliminated.
