Sheet Metal Thickness Measurement

In the automotive industry, sheet metal stamping is the process of cutting and shaping metal alloys into automotive frame brackets and other forms using a press tool.

Metal stamping dies are used to create high precision metal parts that are equal in shape and size.

Automotive metal stamping requires a specific thickness to ensure the parts are equal, andthe die is not damaged during this process. As metal sheets move down the conveyor, laser displacement sensors measure the sheets on a very precise scale to obtain the correct thickness. In this sheet metal stamping application, it is critical that the frame brackets and other metal components are identical and that the die is not damaged to prevent down time and costly repairs. Banner Engineering's LH laser displacement sensor is a perfect solution because it is highly accurate and measures thickness at micron levels.

YOUR BENEFITS

Protects costly stamping dies from damage.
Highly accurate thickness measurement at micron levels, even with dark and discoloured material.
4-20mA analogue or RS-485 communication outputs.

Sheet Metal Thickness Measurement with Banner's LH Laser Displacement Sensor

The L-GAGE LH Series can also consistently look at dark targets on these levels. The LH’s 1024 pixel CMOS linear imager is capable of micrometer-level resolutions ranging from 1-10 microns, which gives it the ability to measure thickness of sheet metal quickly and accurately. Thickness measurements are available with 4-20 mA analog or RS-485 digital communication outputs.

The LH sensor pair self-synchronize to take measurements and calculate thickness within the sensors. The system doesn't require an external controller and is easily configurable using Banner's graphical user interface or GUI, which allows simple networking and monitoring for system-wide visibility of process measurement.

For this specific thickness measurement application, the "master/slave separation," which is two times the reference plus nominal distance, is the ideal separation between the two sensors.
