WDB series bearing sensors are designed to screw directly into a
bearing housing. Each sensor is fitted with a grease zerk to allow
lubrication of the bearing without the need for removal of the sensor.
The WDB8 series have a 1/4” BSPT thread. The WDB2 series have a 1/8”
NPT thread. Three versions are available; an NTC thermistor or Pt100 RTD
type for continuous temperature monitoring, and a PTC thermistor model
with the following trip points (specify when ordering): 60°C, 70°C,
80°C, 90°C for step (Cold/Hot) temperature monitoring.
The sensor is supplied with a three meter attached cable and can be
connected to a hazard monitoring system, such as 4B’s T500 Hotbus Elite,
Watchdog Super Elite, or T400 Elite or to a PLC. The connections are
not polarity sensitive therefore special connection requirements are
eliminated, and the cable can be extended in the field.
