Chain Conveyor Monitoring

4B has a wide range of sensors for monitoring the various parts of your drag chain conveyor. The most common areas for monitoring include: bearing temperature, speed / motion, level / plug indication and slack/broken chain detection.

All of 4B's sensors can be connected to our hazard monitoring systems.

WDA sensor - belt speed / alignment / chain break sensor

Non-contacting extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 100mm away from the sensor. The WDA sensor can be used on bucket elevators to measure speed and alignment by sensing either the metal elevator buckets, or the ferrous bolts attached to plastic buckets. A more specialized use for the WDA switch is as a broken/slack chain detector on drag chain conveyors, or as a non-contact speed switch for screw conveyors.

4B Binswitch

Detects level or plug situations for bulk granular solids or liquids in tanks, bins, or silos and can be used as a plug or choke detector in chutes, conveyors and elevator legs.

M100 Stopswitch

The M1003 Stopswitch is a simple inductive shaft speed monitoring device. The self-contained unit, which signals when the shaft has stopped rotating. It can be used for process control, motion detection and stopped shaft indication. An inductive sensing device located in the nose of the M100 enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. The M1003 Stopswitch requires no calibration and provides an output when the shaft has stopped rotating.

M800 speed sensor

The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions.

4B Whirligig shaft sensor mount

The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.

Watchdog Super Elite hazard monitor (WDC4)
Combined belt speed (slip), belt alignment, continuous bearing temperature, pulley alignment and plug condition monitor for bucket elevators and conveyors.

Hazardmon cloud-basiertes Überwachungssystem

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.

T400N Elite bearing temperature monitoring system

Unique low cost alarm/indicator panel for use with any 4B NTC-type temperature sensors. ADB810, WDB70, and WDB810 series sensors are recommended.
