CASI 951-SS Washdown Checkweigher

The CASI 951-SS is a stainless steel checkweigher rated for NEMA 4X washdown applications often found in food/beverage and extreme environments where manchinery is splashed, washed, or cleaned with various chemicals.
Built on the standard CASI 951, the 951-SS uses a simplified design with 4 compression load cells mounted on a 3" stainless steel frame. This incredibly stable platform delivers superior accuracy and reliability. The scale is available in either rolleror belt over roller, controlled by a 24 volt DC drive allowing for zero pressure accumulation infeed and outfeed conveyor.
| All control is delivered from the rugged CASI Core NEMA 4X industrial PC for standalone or integrated applications such as labeling or sortation. CASI washdown controllers use solid state data storage, an optional touchscreen HMI, and programming and network flexibility only a Windows 7 OS can deliver. | ![]() |
| The CASI Core offers standard Ethernet or serial output Other options include DeviceNet, Profibus, Modbus and Ethernet/IP. | ![]() |
Applications

Specifications
Standard sizes for the CASI-951 range from 18" roller to 36" wide rollers in various scale lengths. 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. Standard accuracy for the CASI 951 is ± 0.1 lbs. and up to ± 0.05 lbs. in intermittant mode.
With any checkweigher, the pieces per minute rate depends upon the item lengths, weights, conveyor speed, and required gap.
CASI-951 Operation
The 951-SS uses a simplified design with 4 compression load cells mounted on a 3" steel frame. This incredibly stable platform delivers superior accuracy and reliability due to a simple but effective design. The conveyor scale can be either belt or roller and is controlled by a 24 volt DC drive allowing for on scale zone control and installation.
CASI-951 Advantages
The optional brake meter belt for the CASI 951 automated check weigh system adjusts conveyor speed to carton length producing the highest throughput available. This option also guarantees one carton on the scale and allows for an integrated reject mechanism for out of tolerance cartons. System carton rate is no longer dependant upon a set scale length and speed, as these can be adjusted to each individual carton.
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 VOIP available.
The CASI 951 includes build in divert logic for carton reject mechanisms like the SortMaster™ series.
