To introduce tensile loading, there is pro v ision for a threaded pin on top of the
housing and an internal thread on the adapter.
Jointed e y elets are suitable for use in the case of quasistatic loading (stress
re v ersal
v
10 H z). In the case of d y namic loading w ith a higher frequenc y , fle
x ible tension bars should be used.
The adapter (3) can be remo v ed b y undoing the scre w s (5). The transducer
can then be scre w ed onto the upper part for taking tensile measurements.
C are must be taken to make the bearing surface on the mounting plate flat.
For attachment use scre w s (5) of at least A270 qualit y (Fig. 4.1). To w ithdra w
them again use torque M
A(5)
(see dimension chart). When the adapter is re
mo v ed the zero signal on the force transducer can change b y
<
1 %. Make
compensating adjustments for this w hen connecting the electronics. When
measuring d y namic forces, the scre w connections to the threaded pin and in
ternal thread must be properl y pretightened w hen the transducer is free of
load: the tightening torque M
A(4)
is listed in the dimension chart. It ma y be e x
ceeded b y not more than 10 %. If a locknut is used, the torque must on no
account be conducted through the transducer.
