Measuring side
Fig. 4.2: Measuring side of the TB2
Mounting sequence:
1. The protective film must be removed before the external centering is
mounted.
2. Use clean, flat (axial run‐out tolerance 0.01 mm) and ground (as far as is
possible) flange surfaces (R
2
> 900 N/mm ; Hardness > 30 HRC).
3. Prior to installation, clean the torque transducer flange and counterflange
plane surfaces. For safe torque transfer, the surfaces must be clean and
free from grease. Use a piece of cloth or paper soaked in solvent. Make
sure that no solvent drips into the inside of the transducer when cleaning.
4. For the bolted measuring body connection, use eight DIN EN ISO 4762
property class 10.9 or 12.9 hexagon socket screws of a suitable length
(dependent on the connection geometry, black, oiled, m
Table 4.1).
WARNING
With alternating loads: Cement all connection screws into the mating
thread with a screw locking device (medium strength) to exclude pre­
stressing loss due to screw slackening.
5. The adapter material should have a yield point of minimum 900 N/mm
tapped threads.
