Watchdog™ Super Elite (WDC4)

New Product

Bucket Elevator & Conveyor Hazard Monitor

WDC4V46CAI, WDC4V4CAI

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).

SPECIFICATIONS:

NTC expansion board for WDC4

Adds 6 additional NTC temperature inputs.  A total of two boards can be added to expand temperature monitoring up to 20 points.

PLC expansion board for WDC4

A discrete PLC input card providing 4 solid state relay outputs for belt speed, belt misalignment, bearing temperature and plug indication.

PT100 expansion board for WDC4

Provides the ability to connect 4 additional PT100 Platinum RTD temperature sensors to the control unit.  A total of two boards can be installed, providing a total of 8 PT100 inputs.

Analogue expansion board for WDC4

Provides the ability to connect 4 current loop inputs (4-20 mA) and 2 voltage inputs to the Watchdog control unit.  Between 1 and 6 sensors can be installed with power and ground connections integrated into the expansion board.

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.

P300 - 30mm Inductive Sensor

Detects the presence or absence of materials. Is used for monitoring the speed of machinery via a speed module or PLC.

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.

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.

4b Touchswitch sensor

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.

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.
