Important
The cable fastening side of the transducer should always be connected dir­
ectly with the rigid customer‐side force transfer areas. Ensure that the cable is
laid so that, where possible, no force shunt is caused by the cable (e.g.
through the weight or stiffness of the cable).

5.3 Mounting for tensile/compressive loading

The transducer is bolted directly (via the ring‐shaped flange faces) onto a
rigid, fully‐bearing structural element (such as a profile, a cover or a plate).
With this method of installation, transducers can measure axial forces in both
the tensile and pressure directions. Alternating loads can also be recorded
perfectly.
• For exact positioning, the transducer is fitted with centering aids on the
upper and lower mounting surfaces.
• The upper and lower bearing pads must be flat and even. The roughness of
the base bearing pad must not exceed R
• The component mounted on the U93 must be sufficiently hard and must not
deform when load is applied. We recommend a hardness of 43 HRC.
• Thoroughly clean the bearing pads before assembly.
• For dynamic alternating loads, the tightening torque for the screws must be
selected so that the screws are pre‐stressed to above the operating load of
the transducer. The requisite data can be found in the table below.
