WTS Web Tension Sensors are used for direct tension measurement in moving webs of paper, films, foils, textiles or metals. Measurement of the precise web tension is accomplished by determining the resulting force that the web directs on to the guide roller connected to these shaft-end sensors mounted at each end of the roller.
It is widely accepted that a well-controlled web operating at defined tension values assures the highest possible end-product quality and is the basis for insuring minimum machine down-times.
The compact WTS sensors in connection with a web guiding roll fulfill 3 functions at once:
precise measurement of web tension
guides and deflects the web
provides bearings for the shafts and rolls
Entire sensor housing as well as the measuring cell are fabricated from stainless steel permits use in the toughest production environments including use in hi-humidity environments
Extremely rugged design is well protected against overloads using integrated mechanical overload stops
Extended operating temperature range is standard
Custom mounting provisions are available
Quick and easy installation due to a variety of clever mounting options: inboard or outboard attachment, flange or pillow block
Special sensor design elements, including high spring constants allows for highest web speeds without affecting the signal quality
Can be installed in vacuum environments without any modification
TS621 Strain Gauge Amplifier
Designed for use with a wide range of strain-gauge-based force, load and tension sensors
