DTW Wide Web Sensors

This is the wide roller DTW sensor with ranges from 1000 grams up to 5000 grams.  Roller widths range from 210mm to 610mm.


Range and Roller Width

Range:  Models from 1000 grams to 5000 grams

Roller Width:  From 210mm to 610mm


Low Cost, High Accuracy

Each unit is equipped with a micro-chip to correct any deviations between units, thus providing a low-cost means of accurate tension measurement.

The units have an accuracy rating of +/- 2% to 4% F.S. depending on the model.



The unit has a high overload rating, and also has no need for adjustment, making it an ideal choice for production line tension monitoring. There is no initial adjustment at start-up.

The sensor is of one-piece construction, and it can be mounted and put to use with no need to adjust or calibrate.


Analog Output

The tension sensor unit provides an analog output signal, which is convenient to use with existing monitoring equipment, digital displays, or incorporate into your existing PLC analog inputs.


Applicable Materials and Applications

These tension sensors work well with any type of fiber such as carbon fibers (1K to 50K), glass fibers, aramid fibers, ceramic fibers, natural fibers, and fiber optics.

Typical applications are for routine quality control, production line tension measurements, high tension or fiber break alarming applications, and R&D laboratory use.
