5.3 Mounting accessories for tensile/compressive loading
Knuckle eyes are available for installing with the Z30A (see page 47). These
mounting accessories prevent the introduction of torsional moments into the
transducer. Using two knuckle eyes will also exclude bending moments, shear
loading and eccentric loading. Knuckle eyes are mainly provided to deal with
static tensile loading on the transducer.
For dynamic loading , Z30A transducers must be installed free from play.
Knuckle eyes have only limited application in the case of dynamic loading,
since alternating dynamic stress increases the play in the universal joints and
falsifies the measured value. It also produces a self-amplifying load cycle
which can destroy the knuckle eyes. The breaking force is only 150% F

Thrust pieces EDO3/1kN or EDO4/50kN (see page 49) and two load buttons
(see page 48) are available for introducing compressive forces.
