STM - Shapemeter roll for strip flatness measurement

Shapemeter roll - sectional strip tension meter - is designed for evaluating of metal strip flatness in cold rolling mills. The principle of the flatness evaluation is based on measuring of pressure forces of a metal strip in the multiple zones of the measuring roll deflector. A visual unit displays measured flatness and tensions across the strip in real time on monitor in the form of a column and flat graphical mapping.

Advantages

• flatness display in I-units
• strip tension distribution display in Newtons
• measuring the flatness and the spread of the tensile force from zero speed of the strip
• measuring the total tensile force of the strip
• no mark on the strip thanks to small bending angle 5°-10°
• affordably priced measuring equipment
• simple construction for maintenance and calibration

Features

• custom built measuring roll with sensitive measuring zones
• industrial PC with visualisation and archiving software
• data output: PROFIBUS or per customer requirement
• OEM version without Industrial PC is possible
