In any type of processing or application where the material will be wound, unwound, pulled or rolled, there will be a need to be able to not only accurately control the tension but to have the system respond to the change in tension either manually or through automatic controls.
Without a way to instantly and continually read and adjust the tension, consistency in the equipment, the process, and the product could not be maintained. This ability to monitor and respond to changes to maintain consistent tension through the system is the responsibility of the tension indicator.
While a comparatively small part and component, it does have a central role in the process. Choosing a durable, reliable, accurate and dependable tension indicator will be an essential choice when setting up a system or when replacing old equipment.
Working Conditions and Tension Variations
As with any type of indicator, these components are designed for specific applications and use parameters. Most models of tension indicators will be versatile enough to work with most application processes but keep in mind the extreme outsides of the upper and lower range and not just the average when making a selection.
Working conditions where the tension indicator is positioned on the equipment often include excessive vibration and perhaps humidity or extreme heat. Always ensure the indicator selected is rated or recommended for those types of applications.
Readout Options
New types of designs in these components tend to favor digital readouts. This provides the exact tension at the time of the display to a specific set level of precision. Analog readouts tend to use a gauge, so they may not have the precision offered by the digital options.
Keep in mind, in hard to read locations it may be easier to see the digital readout, preventing possible operator errors which may be costly.
