WDB Series Bearing Sensors
4B Braime WDB810V3AI WDB Series Bearing Sensors
The 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.

4B Braime Bulldog
The Bulldog alignment and rip detection switch is an electro-mechanical system designed to detect dangerous misalignment of the conveyor and also detection of belt tear damage. The switch will detect horizontal misalignment of belts when contact is made with the roller, the roller arm will be forced to pivot by the belt activating a switch at 20º to trigger an alarm, and 35º to trigger a shut down procedure of the conveyor. The sensors are usually installed in pairs on opposite sides of the belt.
A steel flexible wire is set below the running conveyor belt approx 20-30mm attached by a rare earth magnet at each end. If the belt is ripped or damaged the wire is pulled away releasing the magnet connection which in turn will activate a switch.
4B Braime ADB810V3AI/D8 ADB Series Bearing Sensors
The ADB series have been designed to allow the depth of the sensor to be adjustable depending on your application. A number of versions are available with probe lengths of 50, 100, 200 and 300 mm. The sensors screw directly into a bearing housing through a 1/4” BSPT threaded grease zerk. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor. The ADB series have NTC or PT100 type thermistors which allow for continuous temperature monitoring.
The sensor is supplied with a 3m attached cable and can be connected to a PLC or to a hazard monitoring system, such as 4B’s Watchdog Super Elite, T500 Hotbus Elite or T400 NTC Elite. The connections are not polarity sensitive therefore special connection requirements are eliminated, and the cable can be extended in the field.
4B Braime MDB813V3AI MDB Series Bearing Sensors
The MDB series is a range of bearing sensors manufactured to screw directly into a bearing housing through the existing 1/4” BSPT threaded grease zerk (can be installed in 1/8” NPT grease zerk fitting with an adapter). Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor. The sensor is fitted with a M12 connector for use with a separately supplied cable and socket assembly which can be attached connected directly to a PLC or to a hazard monitoring system, such as 4B’s T500 Hotbus Elite, Watchdog Super Elite, or T400 / T400 NTC Elite. The connections are not polarity sensitive therefore special connection requirements are eliminated. Four versions are available, a NTC thermistor model or PT100 type for continuous temperature monitoring, and PTC or Contact thermistor models with five trip points (60°C, 70°C, 80°C).
