High Accuracy Weighing Indicator Controller , Belt weigh feeder
controller
Main Features:
ARM CPU system with higher arithmetic speed.
Dust-proof stainless Steel shell.
EMC design with high anti-jamming capability, suitable for
industrial environment.
The DC24V power input circuit of weighing indicator has reverse
polarity protection function.
The display information of Bucket Lifting/Declining state,
Single-bucket-loading-weight, Totalized Loading Weight,
Positive/Negative Deviation Value, Alarm state, Date/Time and other
auxiliary data are used for adjusting if
Single-bucket-loading-weight is valid and the loading process
should be stopped.
The information of User Name, Car.No., Goods No., and Operator No.
can be inputted.
High sampling frequency, multiple digital filter and acceleration
compensation algorithm for ensuring high weighing accuracy in the
lifting process of the bucket.
Using two oil pressure sensors for getting higher weighing
accuracy than using one.
24-bit High-precision and high-speed ∑-△A/D conversion module with
1,000,000 internal code used and max. sampling frequency 400Hz.
1000 Loading Records can be saved, queried and printed, and each
record can contain 50 Single-bucket-loading-weight values.
1000 Reload Records can be saved and open for reloading.
