Troubleshooting (Coming Soon)

The Tri-Wheel™ Tension Load Cell is a modular fixture designed to be installed individually or stacked in an array. The system incorporates a set of wheels with adjustable positions, allowing an operator to select from multiple wrap angles. The minimum wrap angle position can be helpful when working with high tension applications or rigid materials with bend limitations. The maximum wrap angle narrows the measurement range of the load cell to deliver the highest possible accuracy and resolution for the selected load rating.

The heart of the Tri-Wheel™ system is a high-performance semiconductor strain gauge load cell providing up to 33 times more signal output than similar foil gauge systems. The Tri-Wheel™ fixture incorporates ceramic pulleys able to withstand wear from steel, copper, glass, carbon fiber and composite filament. Designed with quick integration in mind, the Tri-Wheel™ system is compatible with DFE amplifiers, indicators and controllers featuring Quik-Cal™ technology for rapid, reliable calibration.

HOW IT WORKS
Tension is measured by strain gauges embedded on a dual cantilevered beam and connected in a full wheatstone bridge configuration. As the filament passes over the rotating wheel assembly coupled to the end of the transducer, the beam deflects slightly in response to tension. This produces a voltage signal proportional to tension. The output signal can be displayed as actual tension with a tension indicator or input to a closed-loop tension controller to modulate a torque device and maintain a precise tension set point.
