AM
MINIATURE FORCE TRANSDUCER FOR
COMPRESSION APPLICATIONS
MECHANICAL DIMENSIONS
Main features
• Range of measurement: from 5 to 20 kN
• Accuracy class: 1%
• All stainless steel construction
• Corrosion resistant
• Grade of protection: IP65 (DIN 40050)
• Small size
The AM force transducers series have been designed to measure static and dynamic compression forces.
They are particularly suitable for monitoring pounding operations in compression which require a rugged transducer,
insensitive to high resonance frequencies caused by nonhomogeneous leads in dynamic sequences.
The accuracy and the stability are not affected by continuous
cycling under harsh conditions even with dynamic loads.
The small size of the AM force transducers makes them ideal
for retrofitting in existing equipment.

Cells connected in parallel
In systems that use several cells, the parallel
connection automatically sums the loads on each
individual cell.
Using this method of measurement, the maximum load
will be the sum of the loads on the individual cells and
the sensitivity will be the average value of these cells.
It is important that the user ensures that no cell is
stessed beyond its maximum rating under any load
condition.
