Load introduction

Loads should act as precisely as possible in the load direction. Torsion
moments, off‐centre loads, as well as transverse or lateral forces cause
measurement errors and may damage the load cell permanently. Such
interferences must be intercepted e.g. by stay rods or guide rollers, with these
elements not being permitted to take up any load or force components.
In order to minimize error interferences due to load introduction, HBM offers
various proven load introductions for load cell types HLCB... / BLCB... /
ELCB... (versions with counterbore + thread), depending on the mounting
situation:
see chapter 6.1 "Accessories"
The load cell type HLCA... (version with tapped through hole) is provided for
use with threaded bolt and locknut. Depending on actual use, the threaded
bolt can be screwed into the tapped through hole in both directions. The
locknut will secure the threaded bolt on both surfaces. Please note the
required locknut torques from 40 N⋅m ... 54 N⋅m.
