Jun 13, 2019 · Tension is the pull or strain put on a web of material that tends to stretch it in the machine direction. It can be measured in pounds, ounces, grams, kilograms or newtons across the width of the web.
What is tension? Why is tension important to me? Where is tension control important in the process? How do tension controls work? What is the difference between closed loop and open loop tension controls? Tension is the force applied to a continuous web of material in the machine direction.
The core of the web tension sensors are strain gauge transducers measuring the acting forces. Amplifiers, increasingly common with digital fieldbus interfaces, raise the very low sensor signals to the appropriate levels. The „standard“ measuring system consists of two sensors and one amplifier.
Tension meters are instruments that measure tension in cable, fiber, belts and webs, or sheets. Cable or fiber meters are designed to measure tension of circular cross-section elements. Strap or belt meters are designed for elements whose thickness is less than their width.
In physics, tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression.
