For more complex force measurements a multi axis load cell becomes essential for obtaining results.
6 axis load cell calibration.
A single point load cell is used to measure forces in a single direction.
Shunt calibration of a strain gauge load cell.

This blog describes a detailed test plan for calibrating a 3 axis multi axis load cell in a morehouse universal calibrating machine pictured below.
The abcs uses load cells hydraulic actuators and a computer control and data acquisition reduction program to automatically generate an extensive balance calibration.
Shunt calibration is the known electrical unbalancing of a strain gauge bridge by means of a fixed resistor that is placed or shunted across one leg of the bridge.
It consists of a single machined part of simple geometry with strain gauges placed on the surface.
The design and construction of the load cell is very straightforward.
Six full bridges provide mv v output on six independent channels.
Multi axis load cells are becoming more popular and the calibration of such load cells creates various challenges to ensure minimal cross talk and to calibrate each axis of the load cells.
Load cell concept sandia s six axis load cell is an analog device designed to measure the three vector components each of force and torque that can be applied to the cell.
6 axis load cell calibration.
It is capable of simultaneously loading all six balance components to obtain a third order 6 x 96 balance calibration matrix that is more representative of actual in test load conditions than a calibration produced by manual loading.
The michigan scientific six axis load cell tr6d c 40k has the ability to measure forces in six directions meaning it can measure the x y and z axes as well as the rotation around each axis.
Having the right tools for a job is essential for being able to get the desired results from a test.
