Mechanical installation
Important
Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screws into
the counter thread to exclude prestressing loss due to screw slackening, in the
event of alternating loads.
Notice
Comply with the minimum thread reach as per table 5.1. The maximum thread
reach must be selected so that the counter flange is not touched. Otherwise
significant measurement errors may result from a torque shunt, or the trans­
ducer may be damaged.
