High Precision Compression Load Cell

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.

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.

Description

Areas of application:

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 todays manifold needs of exact reference systems for quality control.
