Product Description

Dual Hoppers Weighing Controller Vibration Resistant Zero Tracking

Description:

GM8804CD is the first dual-hopper bagging controller in the world, which offers a integrated and value adding solution for applications in which multiple hoppers are on a single scale. And It has the same high performance and key technologies while offering lower cost for us clients by controlling two hoppers with a single indicator.

Characteristics:

I/O points (12 input, 16 outputs) as standard
16 keys for combine mode and hopper mode, etc.
Splash proof front panel and keys (IP-65)
User programmed timer settings and alarms
Automatic or manual storage of accumulated data
Easily selectable minimum divisions: 1, 2, 5, 10, 20, or 50
Dust and water-proof display (when mounted into a panel)
Active free fall compensation in dual-hopper packing system
High-speed, highly accurate continuous feeding of powder and grain
Automatic discontinuous weighing systems in bulk handling processes
Advanced interlocked function specially for dual-hopper discharging systems
Improved weighing performance(selectable 6kinds of packing operation mode)
