Summary

Customer Need / Challenge
A fitness machine manufacturer wants multiple load measurement systems for their different fitness machines such as the elliptical, leg press, rowing machine, and the cable machine. They want to ensure the machines functioning properly to prevent injuries. It can also be used for trainers who want to conduct strength and endurance tests.
Interface Solution
A combination of products such as the WMCFP Overload Protected Sealed Stainless Steel Miniature Load Cell, SSB Sealed Beam Load Cells, and AT103 Axial Torsion Force and Torque Transducers. Paired with Interface’s proper instrumentation, the forces can be measured, graphed, and displayed during the testing stage.
Results
Interface’s products all effectively measured forces needed for those working out or undergoing athletic training. Not only did it ensure the machines were working properly, but it also helped those using them to track their endurance performance.

How it Works

Elliptical- Two AT103 Axial Torsion Force & Torque Transducers can be installed inside of the handles of the elliptical. This will measure the athlete’s push and pull forces when in use. Data can be measured when paired with the INF-USB3 Universal Serial Bus Single Channel PC Interface Module, and displayed with the customer’s laptop.
Leg Press- An SSB Sealed Beam Load Cell can be installed under the plate of the leg press. Forces from when someone pushes up on the leg press will be measured using the 480 Bidirectional Weight Indicator.
Rowing Machine- The WMCFP Overload Protected Sealed Stainless Steel Miniature Load Cell is installed in line of the rowing cable, with rod end bearings. When pulled, forces are recorded using the WTS-AM-1 Wireless Strain Bridge Transmitter Module, and transmitted to a PC or laptop through the WTS-BS-6 Wireless Telemetry Dongle Base Station.
