Application

High quality sensors are required due to the constantly rising demand in accuracy and reliability in almost all technical fields. In addition to particularly small linearity errors, measuring applications often call for improved reversal errors, longtime stability and temperature constancy.

This highly precise load cell in combination with qualitatively adequate evaluation electronics can solve many ambitious force measurement tasks. It’s area of application is also extended to include today’s various needs of exact reference systems for quality control.

Examples of application:

Reference sensor for adjustment and control of force measurement facilities in production and in laboratories
Material testing
Spring fame force measurements
Press-in operating
Weighing technology

Description

The high precision load cell model for compression forces consists of a circular body, in which a load button is integrated. The load to be measured is transferred via its convex surface 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 part from lateral displacement when subjected to lateral force. A high level of measurement accuracy requires force application using a flat and hard stamp or plate while the load cell is mounted on a plane surface. The surface should be polished or even lapped and hardened. Its thickness should correspond to the forces in order to prevent bending.

The force should be applied axially and centrically. Even if smaller angle errors influence the measuring signal, they are minimized by the convex and plane surface of the load application button.

Two laterally located M8 threaded holes support the handling and transport of the sensor.
