TU

COMPACT LOAD CELL FOR TENSION/COMPRESSION
APPLICATIONS

MECHANICAL DIMENSIONS

Main features

• Range of measurement: from 50 to 1000 kg

• Accuracy class: 0,2%

• All stainless steel construction

• Corrosion resistant

• Grade of protection: IP67 ( norme DIN 40050)

• Compact size

The TU range of load cells are designed for the
measurement of static or dynamic loads in compression
(output signal: negative) or traction (output signal: positive).
All the transducers are calibrated as load cells in units of
mass (Kg). The TU series is supplied for nominal loads from
50Kg to 1t.
This model has an IP67 protection degree so it can be used
in aggressive atmospheres often found in the chemical
industries. The transducer body is machined from a single
piece of stainless steel with no welding. This means that it is
highly resistant to mechanical shock and vibration.
The compact size means that these cells can be placed in
positions that are difficult to acess and where little space is
available.

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.
