IFF6ADF 6-axis flange force transducer

The 6-component sensors come standard with a so-called Calibration matrix (or with optional advanced calibration "Matrix Plus") delivered. Since the individual signals from the force sensor cannot be directly assigned to a force or torque by multiplying them with a scaling factor, we strongly recommend using the IFFBX8 measuring amplifier. The amplifiers are delivered with the free yet comprehensive BlueDAQ software. The calculation rule can be described mathematically precisely by the cross product of the calibration matrix with a vector of the six sensor signals. For more information, see the description of the calibration matrix, amplifier and software.

Standard calibration
If some measuring axes are not utilized well, the error can occur due to crosstalk in them
Measuring axes have a relatively strong effect, although – based on 100% of the measuring range – it is significantly less than 1%
is.
Advanced calibration “Matrix-Plus”
A new calibration procedure was developed that optimizes the display in the loaded measuring axis and the display in the unloaded measuring axes. The characteristic field of the 6-axis sensor is represented by two matrices. Matrix A describes the linear relationships, matrix B describes the non-linear relationships.
Matrix-Plus with “standard secondary conditions”
When determining the matrices, special conditions are defined so that the measurement errors are minimal even when the measuring range is not fully utilized. Mathematically, loads of 100%, 80%, 60%, 40% and 20% are optimized.
Matrix-Plus with “simulated operating point”
It is even possible to take the application (operating point) into account when determining the matrices: This procedure is referred to as a “simulated operating point”. As a result, accuracies of 1% to 0,2% of the actual value can usually be achieved. In addition to the actual 100% calibration load, the application-specific load vector is also taken into account mathematically.
Matrix-Plus with “calibration at the operating point”
Alternatively, calibration at the operating point of the application is also possible. Custom calibration uses the actual loads and leverage ratios of the custom application. In this case, accuracies of 0,5% to 0,1% of the actual value can be achieved. For calibration, suitable devices may need to be manufactured to reflect the specific leverage ratios of the application. This may result in additional costs and additional costs in individual cases
Delivery times arise.
