What is optical profile projector?
An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. It is a useful item in a small parts machine shop or production line for the quality control inspection team.
Which type of lamp is used in profile projector?
Profile Projector RPP-250 Projection Light Source with 24V / 150W Halogen Lamp. Double Oblique Light Source for Surface Illumination.
What is horizontal profile projector?
Horizontal Profile Projector. Profile Projector (Optical Comparator) is the wise solution to measure the 2.5D dimension of your products. Quantity.
What are the types of comparator?
Types of Comparators
- Mechanical Comparator.
- Mechanical-Optical Comparator.
- Reed Type Comparator.
- Electrical-Electronic Comparator.
- Pneumatic Comparator.
What is least count of profile projector?
In general, the least count of Profile Projector is 0.001mm or 1 microns. In some Make, the least count is more better i.e 0.0001mm or 0.1 microns. Please note that the above least count is the minimum reading which we can measure through inbuilt Digital X-Y counters.
What can be measured on an optical profile projector?
Benefits of Optical Profile Projectors The ability to measure in 2D space in which both length and width of the part can be measured simultaneously results in quick measurements. Imperfections on parts such as burrs, scratches, indentations can be detected on profile projector.
Which instrument is used for calibrating the optical profile projector?
A typical optical comparator illuminates from below and projects the shadow of the measuring object placed on the stage through a projection lens onto a projection screen. For this reason, it’s also known as a profile projector or shadowgraph.
How do profile projectors work?
Profile Projector often simply called a optical comparator is a device that applies the principles of optics to the inspection of manufactured parts.In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits.
What is reed type comparator?
Reed type mechanical comparator is a precision instrument used to compare the dimensions of the workpiece with standard dimensions. In reed type mechanical comparator the external appearance might be the same as what other mechanical comparator looks like.
How many types of projectors are there?
Currently, there are five kinds of projectors you can get for your home: DLP, LCD, LED, LCOS, and laser.
Why profile projector is important in measurement?
Profile projector is widely used for complex shape stampings, gears, cams, threads and comparing the measured contour model. It’s easy to use and highly efficient. The projector magnifies the profile of the specimen, and displays this on the built-in projection screen.
What is a comparator in optical profile projector?
A comparator is a precision instrument used to compare the Dimensions of a given working component with the actual working standard. There are different types of comparators are available. In this article, we are going to discuss the Optical Profile Projector in detail.
What is a profile projector?
For this reason, it’s also known as a profile projector or shadowgraph. At this time, the size of the projected image is an image magnified with a correct magnification from the measuring object, and the dimension of the measuring object is measured by measuring this image.
How does a projector work?
The projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to examine or measure.
What is a shadow graph projector?
Profile projector also known as a shadow graph, and it is useful item in a small parts machine shop or production line for the quality control inspection team. The projector magnifies the profile of the specimen, and displays this on the built-in projection screen.
