A steel mill has a production set up where metal sheets are rolled for desired thickness as they emerge from the production sequence. It is a continuous real time production and measurements have to be made on-line. Suggest a sensor that can do the job. The final output should be electrical.
What will be an ideal response?
A typical answer would involve incorporation of a sensor such as a LVDT to measure the thickness of sheets as the metal sheets emerge from the steel mill. Non-contact thickness gauges such as ultrasonic thickness monitoring units can also be used. In recent years ultrasonic gauges have become more robust. Usage of a sensor depends on the precision and the resolution of the monitoring equipment.
