PR 6201 (500 kg… 50 t)
Precision Compression Load Cell

Product Profile

The PR 6201 range of load cells is specially
designed for weighing silos, tanks and
process vessels.

The unique design principle, in combination
with the FlexLock installation kits, makes
it possible to blance out movements arising
from mechanical or thermal ex pansion or
contraction of the vessel or its supporting
construction.

A particular design characteristic is that the
overall height and shape of the load cell
remain unchanged, from 500 kg up to 50 t.
Alongside this, the unit has an especially
high overload capacity of up to 200 %.

At the same time, this range distinguishes
itself – in addition to its high measurement
accuracy and repeatability - above all for
its unmatched reliability, robustness and
stability, which offer trouble-free operation
without adjustment, year after year.

The pendulum support principle, combined
with patented measuring element geometry,
ensures that force transmission into the
sensor is always at the optimum level and,
in this way, the effect on measurement
accuracy is minimized. At the same time,
the load cell offers a particularly high over­load range, high repeatability and perfect
linearity.

There is an especially wide working tempera­ture range attributable to sophisticated
resistance strain gauge technology. The
hermetically sealed enclosure and special TPE
cable allow the unit to be used even under
extreme operating conditions in harsh
production environments.

The entire measurement chain can be
calibrated without the use of reference
weights. Due to “matched output” techno ­logy, a damaged load cell can be exchanged
without the need for re-calibration. This
saves a tremendous amount of time during
commissioning.

An explosion-proof (Ex) version of this range
of load cells is also available, as an option,
for use in intrinsically safe environments.
