Vertical Profile Projector – PP-300

Vertical Profile Projector, also known as a profile projector or shadowgraph, is a precision optical instrument used for the measurement and inspection of 2D profiles and dimensions of various objects, typically small to medium-sized mechanical components. It is widely used in quality control, manufacturing, and research and development settings.

Key Features and Functions :

1. Optical System: The heart of a vertical profile projector is its optical system, which includes a light source, lenses, and mirrors. The system projects a magnified image of the object’s profile onto a screen.
2. Projection Screen: The screen is positioned vertically and serves as the viewing surface for the operator. The profile of the object is displayed here.
3. Object Stage: The object to be measured and inspected is placed on a glass or transparent stage. This stage can be rotated and moved horizontally to position the object accurately for measurement.
4. Magnification: Vertical profile projectors have multiple lens options to achieve various levels of magnification, allowing users to inspect both small details and larger features.
5. Illumination: The profile projector has a built-in light source, usually halogen or LED, which illuminates the object from below. This backlighting creates a shadow image of the object’s profile on the screen.
6. Overlay Chart: Some profile projectors have an overlay chart or grid that can be superimposed onto the projected image. This grid helps users measure features more accurately and assess deviations from the desired dimensions.
7. Measurements: Operators can use crosshairs or scales on the screen to take measurements of various dimensions, such as lengths, angles, radii, and clearances.
8. Rotation and Tilt: The object stage can often be rotated and tilted to inspect features from different angles, ensuring comprehensive measurements and inspections.
9. Digital Readouts: Many modern profile projectors are equipped with digital readouts that provide digital measurements and can save measurement data for documentation and analysis.
10. Edge Detection: Advanced profile projectors may include edge detection software, which can automatically locate and measure the edges of the object, improving measurement efficiency and accuracy.
11. Software Integration: Some profile projectors can be connected to a computer and integrated with measurement software for data analysis and documentation.
12. Report Generation: Measurement data can be used to generate inspection reports, making it easier to track quality control and compliance with specifications.

Vertical profile projectors are valuable tools for inspecting parts with precision and consistency. They are commonly used in industries such as manufacturing, aerospace, automotive, and electronics to ensure that components meet specified tolerances and quality standards. They are especially useful for non-contact measurement and inspection of objects with complex profiles and intricate details.
