May 2, 2012 – The Millmate Looper Tensiometer load cell (PFTL211-CE) is an excellent choice for looper tension measurement in hot rolling mills. Loopers are often introduced in hot finishing mills between the mill stands to control strip tension deviations caused by variations in incoming material and mill settings. Tension deviations cause thickness and width variations in the finished strip. Most looper systems estimate the strip tension based on looper actuator force and looper arm position. Using load cells to measure the force directly is a faster and more accurate way to determine strip tension and thus yield far better results in thickness control.
The challenge has always been to find load cell systems that will perform well in tough mechanical and chemical environments. The ABB magneto-elastic tensiometer load cell (PFTL211-CE),based on the patented Pressductor Technology, has overcome these environmental difficulties to provide consistent and reliable tension measurement. Millmate Looper Tensiometers are based on the well-known Pressductor Technology, which uses the magneto-elastic effect, according to which the magnetic properties of steel are influenced by mechanical forces acting on it. ABB’s Looper Tensiometer load cells are made in a mill proof version. The load cells are available in two sizes, covering the typical measuring ranges in hot rolling mills.
The Pressductor force transducers inside the load cell housing are well suited for the harsh mill conditions such as dirt, dust, liquids, steam and corrosive environments.
