alpha & Wittenstein Increase Measurement Accuracy

February 18, 2008

New sensor technology from alpha & Wittenstein integrates torque and force sensors into the housing of servo gear reducers, enabling measurements to be more precise. The alphaIQ loads sensors to the gearbox, which allows all mechanical loads to be processed; this includes torques, shear forces, speed, thermal loads, wear and backlash.  Computer software comes with the product, so the variables can be displayed on a PC.
