CM
LOAD CELL FOR COMPRESSION APPLICATIONS
MECHANICAL DIMENSIONS
Main features
• Range of measurement: from 100 to 50.000 Kg
• Accuracy class: 0,2%
• All stainless steel construction
• Corrosion resistant
• Internally generated calibration signal
• Grade of protection: IP67 (DIN 40050)
CM series load cells are strain gauge transducers used to
measure loads in static and dynamic applications, in
compression, with high accuracy.
They are machined from a single block of metal, so the
primary sensing element, the mountings and the case
contain no welds allowing smaller dimensions and an
enhanced grade of protection. The configuration of the point
of measurement, with 8 strain gauges, reduces errors caused
by imperfect applications of the load.
Typical applications of load cells connected in parallel are:
silos, hoppers, large weighing platforms.
The stainless steel construction is suitable for use in
aggressive environments in the chemical and petrochemical
industries.

If the transducer is supplied complete with
prewired connection cable, the colour code
is that indicated in the table.
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.
