The adjustable depth bearing (ADB) temperature sensors have been designed to allow the depth of the probe to be adjustable depending on your application. The sensors are available with probe lengths of 2, 4 or 8 inches, and screw directly into a bearing housing through the existing 1/8-inch NPT threaded grease zerk. There is no need to remove the sensor for bearing lubrication since each sensor is fitted with its own grease zerk. The sensors have NTC type thermistors, which allow for continuous temperature monitoring, and they can be connected to a PLC or to a hazard monitoring system. The bearing temperature sensors are Class II, Div. 1 approved.
