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 IE-Node, 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).
