plate1Arsalis designs and develops force plates. Our force plates include 4 strain gauge sensors measuring the vertical, fore-aft and lateral ground reaction forces. The mechanical design of the force plate is scalable so that it can be adapted to various animal sizes, from mice to elephants. Each force plate is delivered with an amplifier featuring 4 gain ranges, and supplying either analog signals or a TCP-IP interface. Our force plates can be connected in a network (up to 16 plates) in order to set up an instrumented running track. Our force plates demonstrate outstanding performance and reliability as well as competitive pricing.

Arsalis also develops custom force plates of any sizes. Our systems include force plate(s), amplifier, photocell triggers, data acquisition hardware, calibration hardware, fixation base and software for data acquisition and analysis.

The Arsalis force plates output data through the TCP-IP and/or the analog interface. The TCP-IP interface allows versatility and very simple integration of multiple plates. The analog interface allows integration of the Arsalis force plate with existing data acquisition systems like 3D motion tracking systems, electromyography and metabolic energy expenditure measurement systems.

The table below presents the specifications for a 500x800 mm force plate
