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).
- Screw in installation

Monitors
T400 Elite (PTC Version)
Low cost alarm/indicator controller for use with PTC temperature sensors.
The T400 ELITE is a microprocessor controlled unit which works in conjunction with PTC temperature sensors to monitor up to 48 bearings and can cause alarm and shutdown of the machine when alarm conditions are detected. The control unit is housed in a self contained wall mounting enclosure. A test push button on the lid of the control unit provides for full system verification. Alarm and status LEDs provide quick location of the alarm condition, and voltage free relay contacts provide separate alarm and shutdown control. An alarm mute push button is provided on the lid of the control unit and additional connections are provided for an external alarm mute functionality.
T400N Elite
Unique low cost alarm/indicator panel for use with any 4B NTC-type temperature sensors. ADB810, WDB70, and WDB810 series sensors are recommended.
The T400N ELITE is able to accept signals from up to 8 NTC sensors (zones), which are separated into two groups of 4 zones. Each group of sensors is able to cause alarm and shutdown of individual machine when hazardous conditions are detected. There is a total of 2 Alarm and 2 Stop relays. The control unit is housed in a self contained wall mounting enclosure. A test push button on the lid of the control unit provides for full system verification. Alarm and status LEDs provide means of quick location of the alarm condition, and voltage free relay contacts provide separate alarm and shutdown control. An alarm mute push button is provided on the lid of the control unit and additional connections are provided for an external alarm mute functionality. A rotary switch is used to select the temperature alarm value.
T500 Elite Hotbus™
The T500 Elite Hotbus™ is a serial communications system designed to monitor up to 256 sensors for combined belt alignment, belt speed, continuous bearing temperature, pulley alignment, level indication (bin / silo) and plug conditions on bucket elevators and conveyors. With automatic machine shutdown capability and PLC / PC compatibility, this advanced microprocessor based system offers low cost installation, versatility and easy system expansion. Logging and trending software is also available for historic data analysis and preventative or predictive machine maintenance.
HazardMon.com® is a secure cloud based hazard monitoring solution providing status notifications and data logging for bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system's health is detected. An automated maintenance feature allows site operators to verify that all sensors on the system are operational and working correctly.
Watchdog™ Super Elite (WDC4)
The Watchdog Super Elite (WDC4) is easy to install and simple to set-up. The system processes signals from sensors for belt misalignment, belt speed & slip, continuous bearing temperature, pulley misalignment and plug conditions for bucket elevators or belt conveyors. When an alarm is detected it will sound an alarm and provide shutdown control of the elevator/conveyor and feeding system.
A 3.5” LCD screen displays the entire system status at a glance. Password protected controller settings can be set up either directly on the LCD screen, or by a PC application and transferred to the WDC4 via an SD card.
The Watchdog Super Elite can be connected directly to a PLC using the Modbus TCP/IP protocol, or integrated into HazardMon.com®. This secure cloud based solution provides live system status, graphs and historical data that is viewable on any web-enabled device (smart phone, tablet, desktop PC).
