What is Profilometer: This Profilometer is used to find the roughness value of the surface. It is also called as Abbot Profilometer. it consist of a diamond stylus and a spring attached to it which used to vibrates when this meter moves on the surfaceof the measuring object. This type of measurement is used to …
various order of geometrical irregularities on the surface: When the metal is machined by some process, it cannot be perfectly finished and hence irregularities are present on it. There are some geometrical irregularities on surfaces can be classified into various orders. 1. First order: These irregularities are formed in the machine, due to inaccuracies, this …
What is a Comparator: It is a precision measuring device used for comparing the dimensions with that of working standards. It works on the principle of relative measurements. It does not measure the actual dimensions but indicates how the size of the part differs from the working standards. The readings are executed by suitable arrangements. …

Construction and Working of a Sigma Comparator: Sigma Comparator: In this article we will learn a bout Sigma Comparator. What is Sigma Comparator. Construction of Sigma Comparator, Working of Sigma Comparator. It has different types of parts to combine and form a sigma Comparator. There are slit diaphragms, plunger, flexible strips, Y-type forked arm, driving drum, pointer spindle, fixed …
The difference between mechanical Comparator and electrical Comparator is as follows: MECHANICAL COMPARATOR: The Mechanical Comparator has more number of moving parts. Due to more moving parts present in this system there is a high rate of wear and friction. Mechanical comparator is not high accuracy. Readings of this Comparator do not affect by variations …

working of Linear Variable Differential Transformer (LVDT): A Linear Variable Differential Transformer (LVDT) consists of one primary winding and two secondary windings with the equal number of turns wound on a cylindrical former. The two secondary windings are connected in series opposition and are placed identically on either side of the primary winding to which an …
Advantages of Electrical Comparator: Vibrations are reduced due to least weight of mechanical. It consists of less moving parts. By AC supply the friction errors are reduced. For measuring units the indicating instrument can be held at remote locations.
Thread Micrometer: Thread micrometer is used to measure the pitch diameter of the screw thread and it shows the variation in the drunken thread. It is equal to the ordinary micrometer, it is provided with the contact point. It has two ends one is connected with a spindle, and another end has a fixed anvil …
