This comparator is designed for very high magnification. Electrical and Electronic Comparators Metrology Previous post: When correctly adjusted, the image of the index comparatoe is seen against that of the graticule scale. Answer Questions Why do other students get annoyed if one students asks too many questions to the teacher? The amplified mechanical movement is further amplified by a simple optical system involving the projection of an image.

Any slackness in moving parts reduces the accuracy considerably.

Dial Indicator Fitted to Pillar stand: Thus it is obvious that optical comparators are capable of giving a high degree of measuring precision owing to high magnification and the reduction of moving members to minimum. We think you have liked this presentation. The projected image of index line on the graticule can be adjusted by means of screw eren order to set the zero.

Is there a question there?

Any wear, play, backlash millionfh dimensional faults in the mechanical devices used will also be magnified. The usual magnifications of the mechanisms range from about to After Adam and Eve were kicked out of Eden, how did they survive with the millions of dinosaurs lurking about?

Thus milliontu reflected image is not well defined one, as one bright and other blurred image are observed. Two brackets are mounted on a transverse bar carried through the base.

We will need more information to help you. There are other attachments also on the base for various works.

Registration Forgot your password? It is very useful for measuring the internal and external dimensions of cylindrical gauges, screw gauges and thickness gauges. I redshirted my daughter so roolt will start kindergarten at 6. Another advantage of the optical comparators is that provision of an illuminated scale enables readings to be taken without regard to the room lighting conditions.

In the focal plane of the eye-piece, a fine reference line Index is provided and the system of lenses is so arranged that the image mmillionth the scale is projected in the same focal plane. The Optical arragnement of the Zeiss Ultra-optimeter. This comparator utilises both mechanical and optical magnifications and thus is highly sensitive one.

Mechanical Optical Comparators Metrology. It is multiplied by 2, because if mirror is tilted by cpmparator angle 60, then image will be tilted by 2 x A combination of magnifying principles has lead to the development of a few more types of comparators, which are: Becoming a high school teacher in California?

COMPARATORS Introduction: – ppt video online download

Are most 7th graders age 13 by May 1st, because in May you are about to finish the grade and its the end of that grade in May? The optical system of this instrument involves double reflection of light and thus gives higher degree of magnification.

Chat or rant, adult content, spam, insulting other members, show more. If front reflection type of mirror is used, then it requires considerable care in its use to avoid damage to the reflecting surfaces.

The image of the scale and the index line could also be viewed through a projection system. The transverse bar is spiral grooved to allow easy and quick lengthwise adjustment of bracket. In normal back reflection type there are two reflected images, one each from front and back. The mirror is mounted on a knife-edge and it can be tilted about the fulcrum by any linear vertical movement of the contact plunger.

Share buttons are a little bit lower. Why do other students get annoyed if one students asks too many questions to the teacher? Classification of Angular Measurement instruments line and end.

The slight movement of moving block through pointer strip causes the pointer arm to be deflected as shown in Fig. The spider web at the end of the pointer arm is not viewed directly but it is projected through an optical system on a scale as shown in Fig. Optical magnification provides high degree of measuring precision Mp to reduction of moving members and better wear resistance qualities.
