Due to the
constantly rising demand in accuracy and reliability
in almost all techniqual fields sensors are required
that provide an accordingly high quality. Along with a
particularly small linearity error measuring
applications often call for an improved hysteresis
error, longtime stability and temperature constancy.
This highly precise load cell in combination with
qualitatively adequate evaluation electronics can
settle many ambitious force measurement tasks.
Furthermore its application field expands by today’s
manifold needs of exact reference systems
for quality control.

| Description |
 |
The high precision load
cell model 8527 for compression forces consists of a
circular body, in which a load button is integrated.
Via its convex surface the load to be measured is
transferred to the measuring element where it is
converted into an electrical voltage by a strain gauge
full bridge. The output voltage is proportional to the
measuring force.
The measuring element is located between two
stabilizing membranes protecting the central body from
any off-center displacement upon affecting lateral
forces.
Precondition for a high measuring accuracy is a force
introduction through a flat and hard stamp or plate
while the load cell is mounted on a plane surface. The
surface should be correspondingly thick in comparison
to the appearing forces in order to avoid any bending.
Further it should be polished or better lapped or
hardened.
The measurement force should be applied axially and
centrically. Even if smaller angle errors produce
influences on the measuring signal, those are
minimized by the convex
and plane surface of the load introduction button.
Two laterally located threaded holes with M8 support
the handling and transport of the load cell.
