3.07 Scale Mounting, HY Models
The HY design utilized a asymmetric design in that the left and right mounts are slightly
different. One side incorporates a rigid mount that bolts directly to the load cell. The other side
uses a spherical rod end bearing to allow some flex in the mounting structure while minimizing
drift and inaccuracies associated weak or flexing structures.
Although this benefit can be great in many applications it is not always the appropriate mount to
be used. The following list highlights applications that won’t benefit from the spherical bearing
mount, and the symmetrical rigid mount that is also supplied should be used.
The spherical bearing mount may be detrimental in these application
•
Applications with over 150lbs per foot of belt load. (500Kg per meter)
•
Non-top mounted CEMA idlers.
•
Flat carrier idlers or rollers.
•
Belt speeds over 600 FPM.
•
Belt widths over 48” (1200mm).
Consult our factory for unique applications. The HY15 modular scale is very adaptable.
If the application requires a symmetrical rigid mount simply remove the shoulder bolt from the
rod end bearing to disassemble. Then use the two bolts supplied with the rigid mount to attach it
to the end of the load cell. See below.
Because the HY modular scale is in two separate assemblies they need to be mounted parallel
and square with each other. On a standard top mounted CEMA idler conveyor the left and right
modules should bolt directly into the same mounting holes of the weighing idler.
