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).

HazardMon.com®
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.
Hazardmon.com works in conjunction with 4B's Watchdog Super Elite™, T500 Elite Hotbus™ & IE-Node control systems for bucket elevators and conveyors. Both multi-function systems are specially designed to monitor equipment for belt misalignment, belt speed, continuous bearing temperature, pulley alignment, level and plug conditions.

IE-Router
4G Router to connect 4B’s Hazard Monitoring Systems to Hazardmon via 4G Data SIM or Wi-Fi.
Sensors
P3003 & P3004 - 30mm Inductive Sensor
Detects the presence or absence of materials. Is used for monitoring the speed of machinery via a speed module or PLC.
Whirligig®
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.
The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a M12 tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is now simple, safe and reliable.
Binswitch Elite Capacitive Sensor
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.
Touchswitch™
The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. 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 solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.
The face of the sensor is made from hardened and annealed stainless steel, not soft brass or aluminium, so wear life is longer when a belt contacts it. The Touchswitch is not affected by dust or material build up and will still work when completely covered by material. An external test wheel allows for quick and simple sensor/system testing. The sensors are usually installed in pairs on opposite sides of the machine. The sensors can be connected directly to a PLC input, or for greater safety, to a central independent monitoring system, such as Watchdog Super Elite, IE-Node or the T500 Hotbus system.
Auto-Set
The Auto-Set series RF capacitance point level monitors are used for detecting high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers.
The Auto-Set series incorporates simple push-button calibration with microprocessor enable/disable switch for total protection of stored values. Once the Auto-Set is calibrated for the application it never has to be re-calibrated. Data is stored in non-volatile memory so it is not affected by power loss. A four digit LED display shows set values for uncovered, covered and trip settings, allowing simple set-up and adjustment. A set of voltage-free changeover relay contacts are actuated when the level of the material in the container reaches the probe. The unit incorporates a unique power shield which automatically compensates for material build-up around the probe and on the sides of the container, preventing false indication. The solid state electronics are housed in a weatherproof, flame retardant, glass-reinforced nylon enclosure. The Auto-Set is top or side mountable with 316 stainless steel probes lengths up to 10m long.
WDA4 Motion Alignment Sensor
Non-contacting high-power, extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 75mm away from the sensor.
The WDA sensor is designed for use with bucket elevators to detect the buckets in order to measure speed and alignment. It can also detect screw conveyor flights, and ferrous bolts when attached to non-ferrous buckets. A more specialized use of the WDA sensor is for broken/slack chain detection.
The sensor is used in conjunction with a PLC or with 4B's Watchdog™ Elite or A400 Elite control units. Two output signals are provided: one signal is a pulse output, representing each bucket detected: the second signal is a continuous output when moving buckets are detected. The continues output can be wired normally energized or normally de-energized (please see manual).
VIBMIL - Milli-VIB & Milli-Con
VIBMIL is a vibration sensor designed for continuous monitoring of vibration levels in industrial environments. It is current loop powered accelerometer and delivers accurate vibration RMS velocity using a 4-20 mA output. Built with a stainless-steel enclosure, including a 3/4” NPT thread for conduit connection. The VIBMIL can be supplied with optional inbuilt NTC or PT100 temperature sensors (Milli-Con version).
The VIBMIL is equipped with female 1/4”-28 UNF female mounting thread, allowing the use of a screw, stud, or mounting stud to secure the sensor to the desired application.
The sensor is supplied with a 1/4”-28 UNF set screw as standard. Optional converters to M8 and M6 male threads are available.
To achieve maximum sensitivity, mount the sensor vertically along the Y-axis of the machinery.
To ensure accurate readings and proper functioning of the VIBMIL, securely fix it to a level surface during installation.
Implement the 2 wire, loop powered accelerometer into the desired control system and measure the linearised output from 4 – 20mA proportional to the sensors measuring range.
Encoder-Flex 1024
The Encoder-Flex 1024 is a rotary shaft encoder that monitors slide gate position, shaft position, or shaft speed. Examples include position of rack and pinion gates, valves, distributors, and shaft speed on rotating shafts such as slow moving conveyors, mixers, and dryers.
The Encoder-Flex 1024 uses innovative technology to monitor gate position or shaft speed. The resolution is programmable from 1-1024 pulses per revolution and it consists of 4-20 mA output as well as quadrature pulsed output for directional speed, and a Modbus RTU communications for advanced configuration and diagnostics.
There are two status LEDs for easy identification of operational mode and target detection. The unit is quickly calibrated with the touch of a magnet for shaft speed, angular shaft position, or gate position. The sealed body is constructed from stainless steel.
Overheated bearings are one of the main risk factors for dust explosions in bucket elevators and need to be closely monitored.
4B offers a range of Atex, CSA and IECEx certified bearing temperature sensors and compatible monitoring systems.
