Sensors & Measurement Systems for Metal Processing
KELK designs and manufactures accurate electronic measuring and control equipment built to endure extremely harsh conditions. Steel, aluminum, and metal processing producers rely on our systems to keep hot and cold mills running inside spec.
ACOS: Aluminum Crop Optimization System
Automated end-crop optimization for aluminum hot strip mills. ACOS helps mills cut closer to where the usable material ends, which reduces waste and improves yield on every coil.
- Automated end-crop optimization
- Designed for aluminum hot strip mills
- Supported by KELK's measurement and mill application specialists
One Measurement Architecture, Cast to Coil
KELK designs its strain-gage force sensors and optical dimensional gaging to work as one measurement architecture, so mill control systems get consistent, high-accuracy data from cast to coil.
Roll Force: Load Cells
Precision load cells that measure the force applied to work rolls, providing accurate data for mill setup, control, and product quality.
Learn moreRoll Force: Tension
Measures strip tension between mill stands to help maintain consistent gauge, shape, and flatness during rolling.
Learn moreOptical: Width Gage
ACCUBAND non-contact optoelectronic gages measure strip width and centerline deviation in hot and cold rolling applications, using CCD camera technology built to withstand harsh mill conditions.
Learn moreOptical: Crop Optimization
Automated systems that optimize trimming of transfer bar head and tail ends in hot strip mills, reducing material waste and improving production yield.
Learn moreOptical: Velocity & Length
Non-contact measurement of strip speed and length, providing accurate process data for mill control and production tracking.
Learn moreOptical: Thickness Gage
Precision measurement of strip thickness during rolling, supporting tight gauge control and product quality across the mill.

The Rollmax Warranty
KELK Rollmax Load Cells are guaranteed against failure of any kind, however caused, for five full years. Coverage goes well beyond defects in material or workmanship. Mills that upgrade from other brands can calculate in advance what they'll save in replacement cost alone.
Built Into the Mill Process From the Start
From hot mill roughing stands to cold rolling finishing lines, KELK measurement systems are specified as part of the process itself.
Roll Force, Tension & Crop Optimization
Load cells measure roll force directly at the mill stand, while Looper Load Cell Assemblies derive strip tension for mill control systems. Crop optimization, camber, and hot metal detection systems work together to reduce scrap and improve yield across the roughing and finishing lines.
Non-Contact Measurement for Tight-Tolerance Strip
ACCUBAND width gages and laser thickness systems deliver accurate, non-contact measurement in the tight spaces of tension levelers, tandem mill exits, and slitter/rewinder lines. Both are built for continuous, low-maintenance duty.
Force & Dimensional Gaging Under Continuous Load
Camber gages, plate outline systems, and the ALUMIVIEW Crop Optimization System give aluminum and plate producers the dimensional feedback needed to hold shape and reduce yield loss across long production runs.
Rugged Sensors for Critical Inline Applications
Laser-based thickness, flatness, and contour gaging bring KELK precision measurement to camshaft inspection, automotive glass, and other demanding inline process control applications.
