Description The
bending plate inside the load cell is equipped with strain gauges
which, on the exertion of a force, supply a bridgeoutput voltage
directly proportional to the measurement variable. The center axis of
the tension/compression load cells incorporates a continuous thread
through which the measurement force is applied free from lateral or
torsion force either using a load application button or an
applicationspecific adapter part. Starting at a measurement range of 0
... 5 kN, the measurement accuracy is ideal if the load cell has been
mounted on a level, hard and polished base. This condition is not
necessary for small measurement ranges of 0 ... 2 kN due to 3 special
knife-edge bearings (see dimensional drawing 1).
Structural
measures should be taken to avoid exposing the load cell to lateral
forces (for instance, mounting on movable bearings, levers held by
roller bearings). Attachment via the clearance bore holes integrated in
the external ring allows simple handling of the sensor.
A
stop serves as overload protection against damages caused by
impermissible high compression forces (option up to measurement range 0
... 20 kN). Lateral forces of up to 5 % nominal strength only have
little influence.
