Four major monitoring modes and their engineering applications
In the actual testing process, the system provides four different data display methods for engineers to choose according to their needs:
4.1 Profile Monitor
Displaying the changes in contour over time in the form of 3D grayscale images is suitable for analyzing the dynamic evolution of cross-sectional height, such as changes in welding pool shape, uniformity of sealant application, etc.
4.2 Image Monitor
Simultaneously displaying measurement data and contour images facilitates on-site operators to intuitively understand the correspondence between measurement results and physical objects.
4.3 Digital Monitor
Simultaneously displaying the values of multiple measurement items, such as height difference, step height, edge position, etc., is suitable for numerical comparison in batch testing.
4.4 Trend Monitor
Display the trend of measurement data over time, suitable for process stability analysis, such as shrinkage changes during injection molding.

Installation, wiring, and laser safety regulations
6.1 Installation precautions
Sensors and controllers should be installed in an environment free from corrosive gases and strong magnetic field interference.
The grounding resistance must be less than 100 Ω.
The minimum bending radius of the cable is 68 mm to avoid signal interference.
6.2 Requirements for safe use of lasers
Due to the involvement of Class 2 or Class 3B lasers in the system, the following specifications must be strictly followed:
Strictly follow the operation manual to avoid direct exposure to the laser beam.
Ensure that the laser path is absorbed or terminated at the terminal to avoid the harm of reflected light.
If using a mirror reflective object, the path of the reflected light must be controlled.
Do not disassemble or remove the protective casing.
All repairs must be completed by the original factory or authorized personnel.
Laser warning labels must be clearly visible.
When used in different countries, comply with local laser safety regulations.
Common troubleshooting and engineering recommendations
7.1 Measurement value fluctuation or instability
Possible reasons:
Strong magnetic field interference
Multiple reflections caused by reflective surfaces
Excessive ambient lighting (>3000 lx)
Solution:
Increase the average number of measurements (e.g. from 16 to 64)
Use a light shield or change the measurement mode (mirror → diffuse reflection)
Adjust the sensor angle to avoid mirror reflection
7.2 Linearity exceeds specifications
Possible reasons:
The difference between the tested material and the calibration reference material is too large
Sensor lens contamination
Solution:
Re calibrate using standard blocks that are similar to the actual workpiece material
Clean the lens to avoid the influence of dust or oil stains
7.3 Unable to trigger or output abnormality
Possible reasons:
Mismatch in trigger signal level
Poor grounding of power supply
Solution:
Check the external trigger voltage range (should be compatible with the controller)
Confirm that the grounding resistance is ≤ 100 Ω
7.4 Error caused by temperature drift
Solution:
Use temperature compensation function (0.01% F.S./° C)
Using aluminum fixtures to stabilize heat conduction between sensors and the measured object
Application Cases and Selection Suggestions
8.1 Typical Applications
Coplanarity detection of electronic component pins: Use SW2T with a resolution of 0.25 μ m to detect the height difference of connector terminals.
Rubber sealing strip contour detection: using SW6, measuring width ± 20 mm, suitable for the reflection characteristics of soft materials.
Edge positioning of lithium battery electrode coating: using SW17, long working distance to avoid interference with the coating process.
