In food, forage and chemical industry, the users usually need continuous measurement for the particle materials or powder materials feeding into or out of the  warehouse, in order to improve the management, computer controlled quantitative accumulative scale, applying weighing instrument and a scale of double-hopper structure, which has the following features:
1．SCM control system
2．High precision 24 post Σ-ΔA/D convertor to process the signals.
3．Up and down-hopper structure make the continuous weighing.
4．Calculating precisely, the residue in the equipment can be measured automatically.
5． Fully sealing cabinet  is good performance in dust protection.              
6．The equipment can be connected with printer and communication bus
7．New E-RAM, The number can be stored in 10 years
8．Easy to operate, and the pneumatic valve is reliable 

Main technical parameters
1．Static precision: 0.1％F·S
2． Dynamic precision: 0.2％F·S
3．The accumulative value is 999999999999, totally 12 posts, displayed in the LED screen.
4．Pneuamtic valve pressure 0.4~0.6Mpa
5．Instrument supply 220V+10%-15%             
6．Ambient temperature 0~40℃, relative moisture < 90% in no dew place.
