On-Line Tension Sensor with Built-In Amplifier
10 Ranges up 500Kg
Resolution of 0.1% and better
The new CHECK-LINE Model RFSE Tension Sensors measure the running line tensions of yarn, wires, optic fibers, cables, tapes/bands, wraps/webs, foils and similar process materials.
Its unique strain-gauge design delivers excellent measurement precision and stability as well as providing maximum overload protection. They are used in a variety of low and high-range applications, such as measuring 1 or 2 grams on fine denier yarns/fibers to applications measuring wire/cable up to 500 Kg.
Built-in amplifier provides a 0-10 VDC or 4-20 mA output. This sensor requires an unregulated 24 VDC power source. Requires a "zero" adjustment only
