New Interface Multi-Axis Load Cells

One of the common trends in test and measurement is the growing demands for better, more complete sources of data to provide relevant, accurate and viable information to make smart decisions. A significant step towards empowering our customers with more data capabilities is in the ever expanding 2-axis, 3-axis, 6-axis, and axial torsion multi-axis load cell product lines. These requests frequently come with requirements for reduced physical sizes, in dimensions, while keeping the same level of capacity and capabilities. All in the end goal of securing more measurement data.

The benefit of multi-axis is that they are designed to measure a multitude of forces and moments simultaneously with a single load cell sensor. These sensors provide multiple bridges that precisely measure the applied force from one direction with minimal crosstalk from the other axes. We can measure forces simultaneously in three mutually perpendicular axes, with the 6-axis load cells also measuring torque around those axes. Benefits are compounded when these sensors are paired with our data acquisition and amplifier systems that make graphing, logging and displaying data easy enough for any experience level.

As the demand for these products grow across industries, Interface continues to develop new configurations and total system solutions for new and unique applications. We are continuously adding to this line of products In fact, we recently added a few new series of multi-axis sensors aimed at covering a wider spectrum of product tests and custom measurement applications just this month. Included below is a list of the new products we’ve introduced in July, which provide more options to select a multi-axis solution right for your unique needs.

6A Series 6-Axis High-Capacity Load Cells

Interface’s 6A Series 6-Axis Load Cell measures forces simultaneously in three mutually perpendicular axes and three simultaneous torques about those same axes. 12 full bridges provide mV/V output on 12 independent channels. A 72-term coefficient matrix is included for calculating the load and torque values in each axis. Interface’s BX8 Amplifiers, which includes BlueDAQ software, greatly simplifies the data acquisition process. The new Models 6A225 and 6A300 are available.

Interface multi-axis load cells are ideally suited to many industrial and scientific applications, such as aerospace, robotics, automotive and medical research such as orthopedics and biomechanical use cases. In fact, their unique capabilities are helping the medical industry optimize prosthetic design via multi-axis testing. The energy industry is using Interface’s multi-axis products in wind tunnels, and the military is using them to test the center of gravity in aerospace and defense systems applications.

Multi-axis is the future of force measurement. More axes of data gives the users a better idea of the whole testing picture, which leads to better, higher quality products. We’re proud to be leading the multi-axis load cell trend and will continue to serve our customers with new products, and custom solutions designed for every need.

Advancing Load Button Load Cell Capabilities with ConvexBT

Demands for high precision testing utilized for compact designs and in confined spaces is growing. The requirements for quality, accuracy and most importantly reliability are what has driven the experienced engineers at Interface to create the newly released ConvexBT™ Load Button Load Cell product line.

The revolutionary design of the ConvexBT is a first of its kind load button load cell, providing better temperature resistance and more enhanced eccentric load rejection. Miniature load cells categorized as load buttons have been sensitive to off-axis, eccentric or misaligned loads. This means if the load is not exactly perpendicular to the surface it is resting on, the data could become skewed or inaccurate.

Interface designed the ConvexBT™ Load Button Load Cell to confine misaligned loads to the primary axis of the cell providing superior performance in comparison to similar products on the market in repeatability, better data and reproducible results.

As technology advances, there is a growing demand to make devices and products more compact and convenient. This trend is happening across industries and is especially prevalent in medical, industrial automation and products reliant on advanced communications technology. To design and validate these products, our customers need force-sensing solutions that can fit in confined spaces and provide extremely accurate data. This is the driving force behind the development of ConvexBT, the next generation in force measurement device.” – Ted Larson, VP product management and marketing, Interface.
