Fig. 3.1: Assembly diagram
The overall heights of the individual thrust piece, pendulum, transducer and
C18 mounting base assemblies match precisely and the surfaces are
superfinished. So the individual components must not be swapped between
the assemblies.
Each component is uniquely identified by the serial number of the associated
transducer and the position number. (see Fig. 3.2, Marking) The serial number
of the complete K−BU18 / 3MN system is located on the BU18 mounting
base.
The transducers must always be mounted by their respective mounting bases
onto the complete system mounting base.
To minimize reproducibility error, the angular position of the transducers and
mounting bases is specified. When assembled, the cable outputs must point
outward radially. For accurate positioning, there are also markings on all the
mounting bases as well as the measuring bodies. (see Fig. 3.2, Marking)
