Measuring Devices TRIZ Cases

A concentrated force-sensor row in a solid measuring roller cuts vibration error and force shunts for more accurate strip flatness measurement.

A TOF camera tracks strip flatness during hot rolling without heat-sensitive sensors, reducing calibration effort and enabling real-time control.

Multi-frequency electromagnetic sensing measures hot-rolled tube or bar diameter and thickness without radioactive sources or temperature-sensitive readings.

Two magnetic flux directions separate surface flaws from total defect signals, enabling precise inner defect detection in steel plates.

Running-meter tracking links web defects to reel position and process conditions, improving unwinding fault analysis despite thickness variation.

Combined scanning and spot radiation thermometers map both steel plate surfaces after cooling to catch uneven temperature and prevent quality defects.

Dual measurements in high- and low-tension strip zones let one controller switch feedback loops to improve flatness and reduce residual stress.

Periodic tension reduction enables optical strip flatness measurement during endless rolling, cutting roll maintenance while preserving control.

Dual-frequency electromagnetic coils measure hot-rolled profile diameter and wall thickness without radioactive sources, angular scanning, or conductivity-specific calibration.

Continuous thickness and length measurement lets rolled strip cuts align with tolerance zones, improving sorting accuracy and reducing waste.
