Tube detection in heat treatment process
Smart Radar Sensor for width measurement Hot Rolling Mills
Problem Statement
Detecting 30 mm tubes at the furnace entrance is difficult due to thick smoke caused by tube movement and suction, rendering standard light barriers ineffective in the contaminated environment.
Solution
Advantages of thru-beam light barriers over the traditional barriers
- High-intensity transmitter beam effectively penetrates smokefor reliable detection.
- Light bundle reduction tube on the sensor head enablesaccurate detection of small tubes (30 mm diameter).
- Enhanced sensitivity allows small objects to interrupt thepowerful beam, improving detection precision.
