Understanding Tension Load Cells

tension load cellSo…What Exactly DO Load Cells Do?

Load cells come in a great variety of shapes and sizes and all have their own specific purposes, most of which are for industrial applications. Load cells come in several different varieties, pneumatic, hydraulic and strain gauges all have their own uses. A load cell, in itself, is a transducer that is used to measure the amount of a specific force applied to it. As the force affects the transducer, the pressure is converted to electric energy, which is then translated into a usable bit of data. For industrial applications, this information is vital when it comes to stress testing and quality compliance.

What are Tension Load Cells and What do they Do?

Tension load cells are similar to other strain gauges, in that they measure pressure, however the application of a tension load cell is slightly different from that of other cells. The transducer takes the form of a cylinder and is typically installed as a rolling component for specific equipment. Tension cells measure the amount of pressure being applied to the outside of the transducer casing. The pressure and tension readings are measured and the machine can be adjusted accordingly.

The Application of Tension Load Cells

So that explains what a tension cell does, but what is it used for? Tension cells are incredibly useful when it comes to anything that needs to be wound or unwound. Film and ribbons are a good example of this. If the tension is too high, the film can break, rendering it useless and creating a lot of down time as the machine needs to be rethreaded. Conversely, if the tension is too low when the film is winding then the rolls are too loose, leaving them prone to exposure or causing other machines to jam. When it comes to tension, everything has to be “just right” not too tight, and not too loose. Tension cells are also used for more than just film, spring coils are also wound with tension cells to keep the coils from snapping as the metal is bent.

Tension load cells and other strain gauges are vital to the manufacturing world. Not only does it help to cut back on wasted materials and times, but also provides invaluable data for quality assurance testing as well as stress testing. However, it’s not just enough to have them installed, strain gauges and load cells also need to be maintained and calibrated properly if they’re to perform as desired.
