Digital Profile Projector

Model : PPPD-0116 (DRO)

Presto Profile Projector is a strong and reliable measuring tool that is widely used in PET and Preform industries, quality control departments, machine shops, and industrial testing laboratories. It is perfect for checking the quality and measuring different sizes and weights of PET bottles and preforms. This equipment provides a cost-effective way to measure both straight-line and angled dimensions, and it comes with a built-in digital readout (DRO) for easy and accurate readings.

In the PET and Preform industry, the main use of a Profile Projector is to identify the edge or a specific point of a PET bottle’s shadow. This helps in measuring the exact length of a PET bottle or preform from that point. By enlarging the shadow image on the projector, the operator can clearly see where the edge or point starts. These projected profile images are also used to make important decisions, like checking if the size of the bottles matches the standard dimensions and verifying whether any part of the bottle is designed correctly.

Benefits of Digital Profile Projector

A Digital Profile Projector is an advanced optical measuring instrument used for inspecting and measuring the dimensions of small mechanical parts accurately. Its benefits include:

High Accuracy: Provides precise measurement of dimensions, angles, and radii with minimal human error.
Digital Readout: Reduces reading mistakes compared to traditional analog projectors, providing measurements on a digital display.
Time-Saving: Quickly measures complex profiles without the need for physical contact, speeding up inspection processes.
Versatility: Can measure different shapes, including gears, threads, cams, and other intricate profiles.
Ease of Use: Simplifies measurement processes for operators with minimal training.
Data Storage & Integration: Some digital projectors allow storage of measurements and easy integration with computers for further analysis.

How a Digital Profile Projector Works

The working principle of a digital profile projector involves optical projection and digital measurement:

Projection of Profile: The object to be measured is placed on the stage. Light from the projector illuminates the object, casting its enlarged shadow or profile onto a screen.
Magnification: The lens system magnifies the object’s profile on the screen, usually by 10x, 20x, or more, allowing detailed inspection of small features.
Digital Measurement: Digital sensors and encoders detect the position of the profile on the screen. Measurements such as length, width, angles, radius, and contours are calculated and displayed on a digital readout.
Comparison & Analysis: The digital projector allows direct comparison with CAD drawings or templates and can record data for further quality control analysis.

Applications of Digital Profile Projector

Digital Profile Projectors are widely used in industries for quality control, inspection, and precise measurement, including:
