LTT technology combines precision strain gage force transducers with dead shaft mounting options to produce the highest accuracy web tension measurement systems available. LTT series transducers, developed for low force web tension applications, incorporate a differential bending beam design with a full Wheatstone Bridge strain gage coniguration. This design provides stable, accurate, and repeatable measurement over a wide range of operating tensions while virtually eliminating temperature drift. All LTT capacities are equipped with mechanical overload protection. Available with a mounting coniguration for dead shaft applications (with horizontal or vertical support surfaces), the LTT can be rotated to measure the resultant tension force, not just a component of the force. Factory calibration, with closely matched output signals, eliminates ield calibration and costly recalibration after the initial setup. Zero and span settings remain stable for tension forces at the low end of wide rangeability applications. The full bridge design (as opposed to half bridge) provides moderate accuracy when using a single transducer on one end of the roll.
