Load CellsTENSION SENSORS
for Paper and Converting applications

Wide range

High accuracy and repeatability

High overload limit

On-line sensing through DTI

Suitable for both live and dead roller applications.

Dynaspede Load Cells are full-bridge strain gauge-based tension sensors, designed for direct on-line sensing of tension in moving paper, films, foils, wires and cables. They are characterized by extreme linearity, near-zero hysteresis and overload capabilities to withstand rigorous industrial duty applications with electronics to match from Dynaspede range of tension indicators, tension controllers… analog or DSP based.

Digital Tension MonitorDIGITAL TENSION MONITOR

Digital Tension Indicators (DTI), used with Dynaspede Load Cells is admirably suited for on-line sensing and indication of web tension.The unit outputs a signal of 0-0VDC/4-20mA, in terms of web tension. They are available for both face mounting and for independent mounting on the control panels.
