Web Tension Control Systems

a web is any material continuously pulled from a roll through some manufacturing process. Tension is the measurable force that stretches or elongates the web. Web tension control methods range from feeling and controlling tension by hand to advanced systems that automatically measure and make adjustments to the process

Most processes involved in the production or converting of paper, film,plastic, foil, textile, wire, and cable require some form of tension control.It is also necessary on products that require winding onto rolls, printing,coating, laminating, slitting, and extruding.continuous roll fed material,

Properly controlling web tension results in higher quality productand produces greater throughput. For instance, if the tension is notproperly controlled, wrinkles in the material may occur resulting indefective or wasted product

If a roll of material is wound without proper tension control,
the outer layers may crush the inner layers leading to starring
or the inner layers may telescope out resulting in ruined product

When printing on a roll of material, improper tension control results insmeared ink and fuzzy images from poor registration. Applying toomuch tension may stretch some materials beyond their elastic limitrendering them unusable. Proper tension control allows the processto run at high speeds without sacrificing product quality

The terms "load cell" and "tension transducer" are used interchangeably to describe a sensor that accurately measures the tension in a moving web

Installing load cells (tension transducers) is the only accurate way to measure web tension. The measured tension value isthen used to adjust the process to increase productivity

These Cantilever Load Cells are manufactured using high quality raw materials. We being one of the market leading manufacturers consider it our responsibility to provide high quality products to our customers. Thus we send our goods for a number of quality checks. These load cells have a strong construction and durable body. These have a good load tolerance and very long term stability. These products are offered by us in customized designs depending on the need of the customers. These quality load cells we offer are highly demanded in the market.

Specifications:

We are among the leading manufacturers, suppliers, distributors, and traders of high quality Load Cell Amplifier. 

• provides 40:1 tension range when used with 1 or 2 loadcells
• using 4 wire differential technolgy provides a common mode rejection to electrical noise & disturbances resulting in clean & accurate output signal
• with an advance temperature compensation network that cancels out temperature influences
• specially designed to measure low tension 
• can be used with 1 or sum of left & right loadcells

Specification:

With the Cell Transducers we manufacture have a very unique low pressure design. These are mainly used in new machinery or in the machines with tight space. These transducers are corrosion and water resistant, a strong construction and are thus highly durable. These are mainly used with rotating shafts or dead shafts rollers. We being one of the leading manufacturers in the market produce these products using high quality raw materials and even send our products for a number of quality checks.
