Note: This is a good application to approach with MP300 - as the section elongates so its speed increases. MP150 running at 512 pixels and 76Hz was adequate, MP300 makes stronger proposition as you can now more than double this speed for the same pixel count.
EC150 was successfully used at Arcelor Mittal, Differdange in Luxembourg back in 2010 (internal knowledge unless speaking with an Arcelor group company).
The application rolled stock H Beams into train tracks, increasing the length of the beam and subsequently reducing the height. After rolling, the beams were "walked" for further processing (cutting into shorter section).
The temperature threshold function for Automatic Sector in EC150 was created for this project. Prior to this, the Automatic Sector was only detectable by a "slope" value:
The customer had previously deployed 3 Land spot sensors on a moving mechanism to measure the temperature in upper, middle and low sections of the beam. This moving trapezoidal type mechanism proved unreliable in daily use and expensive to maintain and repair.
EC150 combined with an MP150 2M linescanner, using Automatic Sector and Sub-Sector functions, (sectors positioned as a percentage of the Automatic Sector). The maximum sector value for each "virtual pyrometer" was then mapped to an individual analog output channel connected to the customer's control system.
The temperatures were logged to provide traceability of production for each beam and for the operator to make adjustments to the pre-roll temperature.
Advantages:
1. No external moving parts
2. Virtually maintenance free (maintenance check for single window)
3. Easy to configure
4. More accurate/repeatable than 3 separate spot sensors
5. Easy to interpret graphical view
6. Built in OPC server (eventually replace analog modules)
The final system was installed inside a CS Stainless Steel Housing
This system was defined and sold by Adam Ellis and Peter Goebel
