90 kV X-ray gauge for light-gauge strip, on Emerson RIO.
Constant-potential 90 kV X-ray transmission through the strip, stable across mill temperature swings.
Ionization chamber detector with temperature compensation.
Algorithms correct for alloy, pass line and strip temperature before the reading reaches the control system.
Thickness published to Emerson DeltaV over RIO for AGC loop closure.

Thickness range, accuracy and repeatability are quoted per application rather than published. They move with the material, the line dimensions and the mill conditions: the same body holds very different figures on carbon steel and on aluminium, and line speed moves them again. A single catalogue number would be wrong for most of the mills that read it. Tell us the alloy, the gauge range you run and the line speed, and the figures come back with the proposal.
The same gauging body on Allen-Bradley ControlLogix or Siemens S7-1500.
The neighbouring body in the Accura line.
Coating weight measurement for galvanising and tinning lines.
Tell us your strip dimensions, line speed and existing control architecture. Our applications team will return a complete proposal with the figures you will hold on your material.
