7.3.2 Mounting via the central fine thread
The sensor can be used for quasi-static measurements with this type of mounting. Dy­
namic loads are acquired correctly. The sensor must not be exposed to any tensile forces
with this type of mounting.
Use the fine thread completely and please be sure to observe the torques specified in the
table.

7.3.3 Mounting with threaded bushing
The sensor can be used for quasi-static measurements with this type of mounting. Dy­
namic loads are acquired correctly. The sensor must not be exposed to any tensile forces
with this type of mounting.
This type of mounting offers a way to use the force transducer when it is not possible to
insert screw in the four threaded connectors on the force application part.
The threaded bushings are included in the scope of supply.
Screw the threaded bushings into the fine threading of the sensor. Use a screw of prop­
erty class 12.9 to fasten the sensor onto your structural element (see Fig. 7.3). Make cer­
tain that at least six threads are used and observe the torques as specified in the table
below.
