 The
Weigh Frame is a critical part of Checkweighing Systems. In
fact, Checkweighing accuracy is directly related to the dynamics
of the weighing process. If the Weigh Frame isn't stable and
the loadcell free from vibration, weighing errors can result.
The 8120 Weigh Frame for Checkweighing Systems from Thermo Ramsey
has been designed to minimize the effects of vibration and provide
the ultimate in checkweighing performance.
With a
simplified design, the 8120 has a minimum number of moving parts.
This not only helps reduce vibration, but it also means there
are fewer parts to wear out. The simplified design makes repairs
easier and shortens downtime.
GENERAL
DESCRIPTION
The 8120
Weigh Frame
for Checkweighing Systems provides the structure
to move the product over the checkweigher. The frame consists
of the conveying medium (stainless steel, plastic, or micropitch
chain), weightable with loadcell, motor and drive mechanism.
Because
checkweighing is a dynamic or in-motion process, it is subject
to vibrations which can interfere with the accuracy of the weighing
process. These vibrations result from the motion of the drive
motor and conveying media during normal operation. The 8120
Weigh Frame
for Checkweighing Systems improved design prevents
resonance of the weightable structure and provides optimum weighing
accuracy. The stable base and extra rigid framework assures
that there will be no movement within the weigh frame structure
to amplify vibration.
OPTIONS
Conveying
Media - The 8120 Weigh
Frame for Checkweighing Systems is available with
several different conveying media:
- 8120
Nylatron Chain - For lighter products, this light weight,
low friction chain provides maximum accuracy without compromising
durability.
- 8120
Stainless Steel Chain - For heavier products and higher speeds
where a more rugged and durable conveying media is required.
- 8120
Micro-Pitch Chain - For products where high accuracy is required.
- 8120
PWT - Powered belt for unstable products.
