ABB Millmate Strip Scanner Edge Sensor PMSG12x

PMSG12x

The Millmate Strip Scanner Edge Sensor is a brilliant solution to the problem of determining strip edge position during the rolling and post-treatment of metal strip. Satisfactory measurement and control of the edge position can lead to a significant improvement in production economy.

The Millmate Strip Scanner Edge Sensor is a complete unit, enclosed in corrosion-resistant bronze. In the edge sensor there are a number of electrical coils and certain circuits for signal processing. The interior of the edge sensor is well protected by the rugged case and tight-fitting cover. The sensor can easily withstand dirt, liquids and a corrosive environment. Measurement is not influenced in any way by mill coolants. The immunity means that the edge sensor can be placed very close to or even inside the mill stand. However, there must be a metal-free zone above the edge sensor.

Application

The fundamental requirement for measuring strip edge position with the Millmate Strip Scanner System is that the edge of the strip runs over the active measuring area of the edge sensor.

One edge sensor is required for each strip edge. The sensor is mounted in the cross line of the strip and ideally, the top of the sensor should be parallel to the surface of the strip.

Metal-free zone above edge sensor.
There must be a metal-free zone above the edge sensor. Of course, this does not apply to the strip itself, which should run close to the edge sensor. For full accuracy at maximum measurement distance there must not be any metal objects in the metal-free zone.

Best measurement results
An oustanding measurement result will be obtained if the following points are borne in mind when insalling the system:
no metal objects in the metal-free zone above the edge sensor other than the strip itself
edge sensor to be protected from severe impacts from the end of the strip

strip to pass close to the edge sensor at smallest possible distance, 20 – 40 mm recommended
