Bearing Temperature Sensors

BRAIME

WDB8 Series
Bearing Temperature Sensors
APPLICATION
For use on any application where bearing temperature monitoring is required.
METHOD OF OPERATION
The WDB 8 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” BSP thread.
Three versions are available; an NTC thermistor or platinum RTD type for
continuous temperature monitoring, and a PTC thermistor model with the
following trip points (specify when ordering): 50°C, 60°C, 70°C, 80°C, 90°C.
The sensor is supplied with a three meter attached cable and can be
connected to a PLC or to a hazard monitoring system, such as 4B’s T500
Hotbus Elite, Watchdog Elite, or T400 Elite.
The connections are not polarity sensitive therefore special connection
requirements are eliminated, and the cable can be extended in the field.
