Optima HPS

NEW - a revolutionary development in force measurement technology offering a 10-fold improvement over any force platform system on the market. 

Using AMTI’s new optimised strain gauge technology, the Optima HPS provides levels of accuracy never before seen in force platform systems:

  • Average COP accuracy of just a fraction of a millimetre (typically less than 0.2)
  • Crosstalk values typically ± 0.05% of applied load
  • Measurement accuracy typically ± 0.1% of applied load*

AMTI verifies the accuracy of each Optima system through a proprietary Precision Calibration that takes up to 4000 measurements throughout the platform’s entire rated capacity. This process uses a high-density calibration grid that covers the entire platform surface and uses fully documented NIST-traceable standards.

The plots shown in the Optima Human Performance System brochure show the unmatched performance of the Optima Human Performance System. Each intersection of the grids for COP-X, COP-Y, Fz Accuracy, Fz to Fx Crosstalk, Fz to Fy Crosstalk and Fz to Mz Crosstalk represents a physical location at which performance verification data was taken; any platform error is shown on the Z axis.

Each Optima Human Performance System is composed of an Optima Force Platform, Optima Signal Conditioner, Optima Calibration Certificate, and cabling.

The Optima force platforms models available are:

OPT464508 464 x 508 mm

OPT464508HF (High Frequency) 464 x 508 mm

OPT400600 400 x 600 mm

OPT400600HF (High Frequency) 400 x 600 mm

Precision Calibration Overview
Precision Calibration Overview
The calibration of an Optima system is an exacting process involving up to 4000 measurements taken along a 1-inch-grid pattern.

Multiple loads are applied at up to 400 locations using a precision machine capable of maintaining absolute positioning accuracy of 0.005 mm (certified by The Association For Manufacturing Technology).

First, live loads from 50 pounds to Full Scale Capacity (FSC) are applied across the top and sides of the force plate.

Next, dead weights of 50, 100, and 200 pounds (accurate to 0.01%) are used to verify the system’s performance in the physiological testing range.

Finally, secondary characteristics, such as linearity and hysteresis are measured at eight locations using a ten-point-up, ten-point-down calibration protocol.

This exhaustive calibration and verification process ensures that each Optima system offers the best possible quality, accuracy, and performance available.
