SMGZ – Hermetically sealed measuring block for strip tension control

SMGZ
Features
  • IP 67, inert gas filled, chemical, oil and solvent resistant
  • Overload capacity at 10-times nominal force, stainless steel construction
  • 2 year FMS warranty
  • Nominal forces from 2 to 80 kN (450 to 17980 lbf.)

The force sensors of the SMGZ-Series, designed for the measurement of strip tension on continuous metal processing lines, are used in combination with standard pillow blocks. This feature allows for easy maintenance or exchange of the blocks, bearings and roll. Block mounting is simple utilizing four fasteners into the bottom surface and mounting holes for the pillow block bearing are included based on your specifications. In addition, the 6 m cable allows for an electrical connection away from the harsh environment. The SMGZ-Series is available in two measuring, horizontal and vertical, and thus can be specified for use in any mounting orientation and strip wrap configuration. With the superior performance of the SMGZ-Series, accurate tension readings are obtained even with low web wrap angles and high roll weights.
