Dimensions and Mounting Instructions

IMPORTANT This Loadcell must be mounted in accordance with Elphinstone Instructions. Failure to do so may void warranty. Specifications to change without notice. These specifications supercede all previous specifications as of October 2006.

Mounting Requirements

• Top Plate must be dead stiff and machined flat after welding
• Bottom Mounting must be dead stiff
• Bearing plate must be welded using 10mm fillet
• Across end and fully down each side

Precautions

• Do not strike an Arc on the loadcell body with a welder
• It is Ok to use the loadcell to position the Bearing plate for tack welding only
• Remove the loadcell to complete welding procedure
• Do not damage the bottom cover plate as this protects delicate strain gauges
• Take care to protect the loadcell connector/cable as this can not be replaced in the field
• Fit protection for the loadcell connector from stones and foreign objects which may damage it
• Do not damage or paint over the Part/Serial Number identification tag
