5.1 Precautions to be taken when assembling the transducer
• Handle the transducer carefully.
• IMPORTANT!
While assembling the couplings, don’t overload the transducer, even
temporarily. It is highly suggested to connect the transducer electri
cally first and monitor the torque signal in order to prevent exceeding
the torque range!
• Axial and radial misalignments must be avoided.
• Make sure the enclosure is correctly connected electrically to
the grounded parts.
5.2 General assembly guidelines
The drive and transducer sides should not be swapped, otherwise measurements
(readings) will be invalidated during accelerations, for example.
When reading the device label, the drive side is on the right and the transducer
side on the left of the transducer. There is a small cavity in the cover on the mea-
surement side.
Flexural, axial and radial forces are disturbances that cause incorrect measure-
ments
Be careful with the thermal expansion of the assembly.
