Why the VRWSP 900 Outperforms Traditional Measurement Systems from EMG Automation 

In the metal processing industry, accurate measurement systems are essential for maintaining high product quality and production efficiency. EMG Automation offers a range of solutions for strip guiding and position measurement, but their traditional systems can sometimes face limitations when confronted with challenging conditions such as dust, high temperatures, and environmental interference. The VRWSP 900 provides an advanced solution that surpasses traditional systems from EMG Automation in several key aspects. 

VRWSP 900 vs. Traditional Strip Guiding Systems 


Traditional strip guiding systems from EMG Automation, such as their iCON® series, use optical and inductive sensors to determine the strip's center position. While these systems are reliable under normal production conditions, they can be affected by: 
  • Optical Interference: Dust, steam, and poor lighting can reduce the accuracy of optical systems. 
  • Inductive Sensor Limitations: Inductive sensors are sensitive to electrical noise and perform poorly in the presence of conductive liquids or very thin metal strips. 
  • Temperature Constraints: High-temperature environments, often found in metal processing, can affect the performance of traditional optical systems. 
The VRWSP 900 overcomes these challenges by utilizing radar-based technology, providing unmatched accuracy and performance even in demanding environments. 

Advantages of the VRWSP 900’s Radar Technology 


The radar technology used in the VRWSP 900 offers several advantages compared to traditional systems from EMG Automation: 
  • Unaffected by Environmental Conditions: Unlike optical systems, the VRWSP 900 is not influenced by dust, smoke, or other visual interferences, ensuring consistent performance even in harsh environments. 
  • Accurate Position Detection: The millimeter-wave radar technology enables precise measurements even in the presence of disruptive factors, such as electrically conductive liquids, where inductive systems typically struggle. 
  • Flexibility in Passline Variation: The VRWSP 900 can handle passline variations of up to 20 mm without affecting measurement accuracy, which is challenging for traditional systems to achieve. 

VRWSP 900's Performance in Demanding Environments 


While EMG Automation systems have proven capabilities for many standard applications, the VRWSP 900’s radar-based system offers superior performance in particularly demanding environments, such as: 
  • High Temperatures: Maintaining measurement accuracy up to 180°C, the VRWSP 900 is ideal for hot rolling processes where traditional sensors risk overheating or damage. System can equipped with thermal protection to handle even higher temperatures. 
  • Near Deflector and Guide Rolls: The radar-based system can accurately determine the strip’s position and width, even near metallic components that typically interfere with optical or inductive sensors. 
  • Presence of Conductive Liquids: While inductive sensors struggle with such conditions, the VRWSP 900 maintains its accuracy and performance. 
  • Sensors located outside strip area :  There is no risk for sensors getting hit by the strip in case of strip breaks or strip bulging up in the process line since sensors measure are located outside the strip area.
