Tension force transducer TR series

Users are delighted with the precision performance and robust reliability of the TR Tension Roll® transducer, a unique sensing device for accurately measuring process web tension in any substrate. A dead-shaft idler roller with tension sensors built into each roll end, the Tension Roll® transducer is ideal for installation on original equipment or for retrofits since it arrives pre-assembled and ready-to-install between the facing sides of a machine frame. It can be inserted into an appropriate web path location, and an accurate web tension value can be displayed on a connected indicator or controller. No assembly required. With the TR transducer the engineering time required to size the unit to the machine frame prior to installation is significantly lower than when installing standard shaft-end load cells or tension transducers onto an idler roll. Another advantage of the Tension Roll transducer over a conventional idler roll with transducers is that it requires only a single transducer cable to connect at one end of the roll. The transducer's connector cable never has to cross the machine. For web presses and machines that run an extreme range of materials and tensions, the Tension Roll transducer can be mounted in a pair of DFE's model C shaft-end tension transducers . This allows one range of tensions to be measured by the Tension Roll's sensors, while a higher load range can be measured using the externally-mounted tension transducers. This feature is convenient in the rare cases that a machine's tension range exceeds the 100:1 maximum-to-minimum tension ratio of DFE's extended range option.
