July 12, 2009 – Promess added a series of hollow-shaft units to its line of Torque Functional Test (TFT) systems intended for intelligent assembly applications. Based on direct drive rotary motor technology, the TFT-HS series permits users to access components with tools and/or sensors inserted through the center hole during the assembly operation.Promess TFTs provide monitored and measured amounts of torque during assembly and test operations. They utilize servomotors, precision position sensing feedback technology, and extremely accurate, proprietary torque transducers to produce controlled torque inputs and feedback monitoring.The new Promess TFT-HS series includes models ranging in size from 20Nm to 300Nm at speeds up to 800rpm.
Full scale torque sensor accuracy is 2 percent, and repeatability is 0.25 percent. A full range of customized features and standard options are also available.
