STM - Shapemeter roll for strip flatness measurement

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 acros 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 deflector 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
