When installing the reference torque measuring disc as a comparison
standard in calibration test benches, the torque to be measured is introduced
from the measuring side (see Fig. 4.2).

Assembly sequence:
1. Use flange surfaces (minimum material strength > 900 N/mm
hardness > 30 HRC) that are clean, flat (run out tolerance 0.01 mm) and
as polished as possible ( R
2. Prior to installation, clean the plane flange surfaces of the
torque measuring disc and of the counter flanges. For safe torque transfer,
the surfaces must be clean and free from grease. Use a piece of cloth or
paper soaked with a solvent. Make sure that no solvent drips into the
gaging flange's interior.
3. Use eight DIN EN ISO 4762; black/oiled/m
screws, property class 10.9 (measuring range 10 kN⋅m: 12.9), of the
appropriate length (depending on the connection geometry, see Table 4.1)
to screw fasten the measuring body.
We recommend, particularly for 100 N⋅m and 200 N⋅m situations,
fillister head screws DINEN ISO 4762 or similar, blackened,
smooth headed, permitted size and shape variance in accordance with
DIN ISO 4759, Part 1, product class A.
