4.3 U2B installation for tensile loading

To introduce tensile loading, there is provision for a threaded pin on top of the
housing and an internal thread on the adapter.
Jointed eyelets are suitable for use in the case of quasi static loading (stress
reversal v10 Hz). In the case of dynamic loading with a higher frequency, fle
xible tension bars should be used.
The adapter (3) can be removed by undoing the screws (5). The transducer
can then be screwed onto the upper part for taking tensile measurements.
Care must be taken to make the bearing surface on the mounting plate flat.
For attachment use screws (5) of at least A2 70 quality (Fig. 4.1). To withdraw
them again use torque M
moved the zero signal on the force transducer can change by < 1 %. Make
compensating adjustments for this when connecting the electronics. When
measuring dynamic forces, the screw connections to the threaded pin and in
ternal thread must be properly pretightened when the transducer is free of
load: the tightening torque M
ceeded by not more than 10 %. If a lock nut is used, the torque must on no
account be conducted through the transducer.
