Now with continuous bearing temperature monitoring

The 4B Watchdog Elite, which has established itself as the industry standard product for hazard monitoring in bucket elevators and conveyors, has now been relaunched with continuous bearing temperature monitoring.

A multi-functional hazard monitor that monitors belt and pulley alignment (top and bottom), bearing temperature, belt speed and blocked chute conditions, the 4B Watchdog is a comprehensive monitoring system that allows complete monitoring of multiple hazards in a bucket elevator or conveyor.

The Watchdog system uses a range of compatible sensors to monitor different hazards, such as the belt misalignment sensors "Touchswitch", BAP2" and WDA3", the WDB bearing temperature sensors and the "Binswitch" capacitive sensor.

An LCD screen displays elevator status messages (available in four different languages) and a super-bright LED screen displays belt speed.

All units automatically select supply voltages from 110VAC to 240VAC (50-60 HZ) and supply the sensors with fully regulated 24VDC power supply. Voltage free relay contacts are provided for alarm and stop, for underspeed, misalignment, and temperature.

RS485 communication is also available for connection to plant computers / PLCs. Simple menu-driven calibration and parameter adjustment.
