Specifications
Standard CASI 921 in-line scale is 36" long by 24" wide. Custom sizes are also available with additional lead time. Standard product weight range is from less than 1 lb. to 100 lbs., with custom product weight range also available. Accuracy for the CASI 921 is up to ± 0.01 lb.
With any Checkweigher, the parts per minute rate depends upon the item lengths, weights, conveyor speed, and required gap.
All control is from the ruggedCASI 1100 industrial PC based system controller. The 1100 offers redundant hard drives & power, a 19 inch high resolution HMI and the programming flexibility only available via a Windows XP product.
CASI-921 Operation
The CASI-921 unattended intermittent checkweigh system uses a simplified design with a single compression load cell mounted on a massive four inch steel pedestal. This incredibly stable platform delivers superior accuracy and reliability due to a simple but effective design.
CASI-921 Advantages
The built in zero pressure accumulation control of the CASI-921 automated check weigh system can automatically bring in and release cartons at rates up to 15 per minute. Cartons identified by scanners requiring greater than .01 lb. accuracy can be allowed a longer weigh time with proper accumulation. Logic for an integrated reject mechanism for out of tolerance cartons is also provided.
Checkweigh Manager is
an advanced checkweigh system management module that ships free
with every CASI checkweigh system. The built in operator HMI and
I/O control allows each checkweigh system we sell to perform conveyor
control functions as well as interface to barcode scanners and
other peripheral devices. Remote support is provided standard
with optional Voice over I.P. available.
The CASI-921 includes divert logic for carton reject mechanisms like the SortMaster™ 100 Series. Divert rates of 30 cartons per minute are possible.
Options / Accessories
The CASI-921 offers the widest array of options of any in motion weighing system on the market. Our custom integration service will customize the system to your specifications by including fixed position barcode scanners, RF Tag Readers, Product Diverts, Carton Dimensioning Systems, and more. Some of the more popular options are listed below:
- NEMA 4X Stainless Steel
