A measuring assembly with a mechanical excitation device that excites the metal belt of a transport device at an excitation frequency (fA) to produce mechanical vibrations. Analog measurement signals (MA) characterizing the amplitude (A) of the excited mechanical vibrations are detected for corresponding regions of the metal belt using sensor elements. The measurement signals (MA) are digitized with digitization devices and the digitized measurement signals or signals derived therefrom are transmitted from the digitization devices to an evaluation device arranged outside of the measuring assembly as transmitted signals (MA). The sensor elements comprise eddy current sensors.

When the sensor elements are viewed as a whole, a plurality of sensor elements are operated using the same operating frequency (f1, f2, f3).

A remote tension measurement system and method of use is provided for detection and estimation of tension in two-dimensional and three-dimensional inflatable structures. Given a spacing distance and a known mass of the membrane-formed structure, measurement points are determined to define a measurement region of the structure. A non-invasive sensor monitors the measurement points to detect a transverse wave moving along the measurement region at an angle to a straight path between measurement points. Propagation speed for the transverse wave is calculated and tension for the measurement region is deduced from the calculation. The solution exploits either proactively introduced, pre-existing, induced by normal environmental conditions) and/or multiple transverse vibrations in the membrane-formed structure. Propagation speed is calculated deterministically based on an analysis of the arrays of measurement points.

Systems and methods for measuring web tension distribution in roll-to-roll processes, for example, such as R2R processes employed in the fabrication of printed devices. Such systems and methods entail a web that travels between first and second rollers in a longitudinal direction of the web, inducing tension in the web in the longitudinal direction thereof such that tension is present in a flexible substrate of the web between the first and second rollers, and operating the system to determine an average tension and linear variation of tension present in the flexible substrate resulting from the tension induced in the web inducing a nonuniform tension distribution in the flexible substrate between the first and second rollers. The systems and methods utilize one or more devices that induce deflection in the web between the first and second rollers.
