Conveyor monitoring system

47 WatchdogMaterial handling and electronic component specialist has released the fourth generation Watchdog Super Elite (WDC4) control unit for monitoring bucket elevators and conveyors. It processes signals from up to 15 sensors for belt speed, belt misalignment, continuous bearing temperature, pulley misalignment and plug conditions. When an alarm condition is detected, the system logs the details, sounds the alarm and provides shutdown control of the elevator/conveyor and feeding system.

A new 3.5-in. color graphic LCD screen displays the entire system status at a glance. The WDC4 supports belt speed monitoring for variable frequency drives, and belt misalignment inputs for contact, pulse and temperature (brass rub block) sensors. The control also has jog and acceleration monitoring for detecting any equipment issues during the start-up sequence.

Controller settings are password protected, and can be set up either directly on the LCD screen, or by a free PC software application and transferred to the WDC4 via an SD card. The Watchdog Super Elite can be connected directly to a PLC using Modbus TCP/IP protocol, or integrated into HazardMon.com, a secure cloud-based solution that provides live system status, graphs and historical data viewable on any web-enabled device. 4B Components Ltd., Morton, Ill.; www.go4b.com/watchdog
