What is the use of optical profile projector?
An Optical Profile Projector is perfect and effective combination of optics, mechanics, electronics and software to provide small parts two dimensional measurements and other mechanical parts.
What is projector profile?
A profile projector is an optical measuring instrument used in metrology and quality control. This device allows the shadow of the part to be measured to be projected on a screen which is then used by the operator to perform the measurements.x. It’s the principle of Chinese shadows, but it still works very well today.
What is the working principle of profile projector?
When an object is placed in between condenser lens and the light source, a shadow of the profile is projected at some enlarged scale on the screen. this enlarged profile will be used to compare with the working standard. Here, Lenses plays a significant role in the magnification of the profile(Image).
How many types of profile projectors are there?
Types: There are three type of profile projector available in the market which are i. Bench type ii. Vertical type iii. Horizontal type You can get profile projector at Sinowon Innovation Metrology Manufacture Limited.
What are the disadvantages of profile projector?
The limitation of using profile projector as a fixed device forms a disadvantage of it, while instruments such micrometer or calipers can be used to reach for measuring far and joint accessible components and it is large and bulky and usually require a cart to transport from place to place, also the device requires …
How accurate is a profile projector?
Magnification accuracy : 0.08% contour, 0.12% surface. Equipped with DC-3000 data processing system and foot-switch for measuring. Erect image measuring for different requirements.
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 the advantage of projector?
Projectors reflect light; TVs emit light. Reflected light is less straining, more comfortable. Projectors produce bigger images. Larger images create easier viewing, less strain.
What are the advantages of profile projector?
Advantages. Profile Projector can reveal imperfections such as burrs, scratches, indentations or undesirable chamfers which both micrometers or calipers can’t reveal. They’re able to measure in 2-D space.
What are the parts of profile projector?
Profile Projector / Optical comparator Calibration

How often should a profile projector be re-calibrated?
Continuous use of Profile projectors for long time can make the system go out of calibration. Therefore it is required to re-calibrate them every year. A typical calibration routine involves the following: 01. Focus squareness parallel to optical axis. 02.
What kind of mirror is used in pj-h30?
Models in PJ-H30 series of optical projector is supplied with an oblique mirror.) The magnification accuracy of a projector is dependent on the type of lens and miror are used. glass scale is also known as `stage micrometer’ or `standard scale’, and the projected image of this is measured with a larger glass scale known as a `reading scale’.
