(microcator), a measuring instrument whose mechanism is in the form of a tape spring twisted in the middle part, which rotates through a definite angle upon tension (Figure 1). It is used for linear measurements by the relative contact method.

What is mechanical optical comparator?

Mechanical-Optical Comparator • Mechanical optical comparator consists of plunger which is attached with lever and a mirror on which the light strikes from the source. They have a less number of mechanical moving parts, hence less friction and inertia effect, and gives higher accuracy 2.

What is the principle of mechanical comparator?

Dial Indicator is the most commonly used mechanical comparator. It works on the principle of Rack and pinion system i.e., the linear movement of the spindle is magnified by rack and pinion arrangement.

What is the advantage of mechanical comparator?

Advantages of Mechanical Comparators They are cheaper compared to other amplifying devices. the outside sources do not affect the accuracy. They have a linear scale robust and easy to handle. It is suitable for ordinary workshop and also easily portable.

What are types of mechanical comparator?

Different types of mechanical comparators are:

• Dial Indicators.
• Lever Comparators.
• Sigma Comparators.
• Johanson Mikro kator. ADVERTISEMENTS:
• Read type Comparators.

  How are all mechanical comparator effected?

  Mechanical comparator employs mechanical means for magnifying small deviations. The method of magnifying small movement of the indicator in all mechanical comparators are effected by means of levers, gear trains or a combination of these elements.

  What are the types of comparator?

  Comparators are classified into various kinds, such as electronic, electrical, mechanical, optical, sigma, digital and pneumatic comparators, these are used in various applications.

  What are the advantages of optical comparator?

  Advantages of Optical Comparator High accuracy will be achieved as it has very few moving parts. Less weight than other comparators because of fewer parts. The parallax error will be avoided. Due to the high magnification, very suitable for accurate measurement can be obtained.

  Which instrument is an example of mechanical comparator?

  Dial Indicators: A dial indicator is simplest type of mechanical comparator. It is very versatile and sensitive instrument. It uses gear system together with a rack and pinion.

  What is comparator and its application?

  A comparator is an electronic component that compares two input voltages. Comparators are closely related to operational amplifiers, but a comparator is designed to operate with positive feedback and with its output saturated at one power rail or the other.

  What is the purpose of a mechanical comparator?

  A comparator is a precision instrument used to compare the Dimensions of a given workpiece component with the actual working standard. Mechanical Comparators are the type of comparator which is made up of mechanical means.

  How are the different types of comparators different?

  The different types of comparators are following. Mechanical Comparator. Electrical – Electronic Comparator. Read type Comparator. Pneumatic Comparator. Mechanical – optical Comparator.

  How is magnification occurs in a mechanical comparator?

  In this type of comparator, the magnification is occurred by the mechanical devices and mechanical linkage. The mechanical comparator is a measuring instrument, the mechanism of this instrument is tape spring twisted and it is positioned in the middle part.

  What is a reed type mechanical comparator for?

  Reed is a Long supporting rod/Shaft. In Reed type mechanical comparator we use a number of Reeds to avoid frictional contacts. See the following image of a Reed type mechanical comparator.
