Dual Hoppers Bagging Load Cell Indicator 16 Buttons With Beeping Feedback
?
?
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)
