BFI SHAPEMETER ROLL

Product catalog summary

Application: The BFI Shapemeter Roll is designed for measuring the shape of metal strips using piezoelectric load sensors based on a patented method by VDEh-Betriebsforschungsinstitut (BFI).

Advantages: The roll features a solid body with a homogeneous steel surface and a patented partition system for wedge strip measurement. It can be reground using standard grinding machines for deflector rolls.

Process Parameters: The system is suitable for metal strips with a speed greater than 5 m/min and a thickness of at least 0.005 mm. Maximum strip tension varies with roll diameter and width.

Measurement Parameters: The system uses piezoelectric load sensors with three switchable measurement ranges, a resolution of 0.1 I-unit, and accuracy of less than 2 I-units. It can handle strip temperatures up to 180°C and features sensor linearity of less than 0.3% and hysteresis under 0.5%.

Design and Dimensions: The roll has axial bores for sensor placement, a hardened steel surface, and various bore configurations based on wrap angle. Roll diameters range from 200 to 500 mm, with specific width requirements based on diameter.

Connections and Environment: Interfaces include PROFIBUS DP and Ethernet, with a supply voltage of 110-230 V AC. The system operates within a temperature range of 0-45°C for the gauge and 5-35°C for the control cabinet, with a relative humidity tolerance of 0-95%.

Options: Additional features include shape control adjustments, a patented partition system for wedge strips, width and position detection using CCD cameras, and various coating options such as chrome and tungsten carbide.
