On-Line Tension Sensor

RFS
RFSE (Built-in Amplifier)

The new CHECK-LINE Model RFS/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.

 


Resolution of 0.1% and better

Overload protection up to 800%

Rugged stainless steel housing is environmentally sealed

Threaded housing with lock-nuts permits easy mounting and simple alignment

 

 Wide variety of precision, ball-bearing mounted guide rollers are available

Supplied with a 10 ft. (3 m) shielded cable. Optional lengths are available

 
Model RFSE Additional Models Available
3-Roller Designs
The RFS/RFSE sensors can be supplied in a 3-roller design incorporating outer guide rollers. A wide variety of configurations is available.
Tapes, Webs & Warps
A flat, cylindrical roller, with or without flanges, is offered for tapes, bands, warps and webs in various sizes up to 400 mm wide.
Custom Designs
For unique applications, a custom design can be developed to meet most requirements.
Type 24
Same as RFS Sensor with a built-in amplifier providing a 0-10 VDC or 4-20 mA output. This sensor requires an unregulated 24 VDC power source. Requires a "zero" adjustment only.
Custom sensor designs can be developed to meet specific applications requirements. Inquire.
