Bulldog
Conveyor Belt Alignment & Rip Detection Switch
MBA2AI, MBR2AI

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.

Watchdog™ Super Elite (WDC4)

Watchdog Super Elite hazard monitor (WDC4)
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).

T500 Elite Hotbus™

T500 Elite Hotbus™ elevator & conveyor monitoring system
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.

B400 Elite Beltswitch

B400 精英型皮带跑偏控制器
B400 Elite Beltswitch

The B400 Elite Beltswitch belt misalignment monitor uses 4B Touchswitch sensors to monitor belt alignment in bucket elevators and conveyors. Each control unit incorporates two independent monitoring circuits for early detection of belt misalignment on one or two bucket elevators / conveyors. The 4B Touchswitch is an electro-mechanical limit switch with no moving parts. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. Status LEDs on the control unit indicate the alignment condition of the belt, while internal relay contacts provide alarm and automatic shutdown of the elevator when hazardous misalignment conditions are detected.

Hazard Monitoring Design Service

Hazard Monitoring Design Service

Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.

4B provides an extensive range of their own ATEX / IECEx / CSA approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.

And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.

We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.

To get a recommendation from our engineers, please fill in the electronics questionnaire below. Please fill this form in as accurately as possible to allow us to deal with your enquiry more effectively.
