MOUNTING A TAT LOAD CELL AND APPLYING THE LOAD

Rev. B

MOUNTING:
TAT loadcells in their standard configuration can be mounted in either by the use of an adhesive or by clamping.  Nonstandard loadcells are available with thru holes or tapped holes if required by the application.

The easiest mounting technique is to simply glue the fixed end of the loadcell to a fixed surface.  Only the free surfaces of the center section need to remain free of glue.   While it would be best to glue the loadcell to an aluminum surface, for most applications the loadcell can be glued to other surfaces, but in that case the glue should be of highly compliant type to minimize differential thermal expansion effects.  The loadcell can also be clamped across its width in a direction perpendicular to the sensing axis.  For a small cost increment, holes can be drilled or tapped in the fixed end of the loadcell at positions defined by the user.


LOAD APPLICATION:
TAT loadcells are exceptionally insensitive to the precision to which the load may be misapplied.  For all but the highest accuracy applications, the load can be applied anywhere along the three inner sensing surfaces as shown on the outline drawing where the visible surface which is draw in crosshatch.  There is no need for a spherical load button.

The specific method of load application is dependent on whether the load is tensile or compressive and the way in which the loadcell is to be used.  Refer to the "Products" page and the accessories discussion.
