Springer Handbook of Mechanical Engineering pp Cite as. In addition to diverse technical requirements are also to consider the requirements of national, international and company-specific norms. The companies must not only fulfill the requirements of the quality, but also the requirements of safety, environment and economy.

Measuring Instruments plays a vital role in the Engineering Workshop. The Instruments duty is to measure the given specimen according to the given dimensions. In the last class, we had discussed Angular Measurements and Linear Instruments in a detailed way.

Mechanical Instruments and Tools

The vernier, dial, and digital calipers give a direct reading of the distance measured to high accuracy. They are functionally identical, with different ways of reading the result. These calipers comprise a calibrated scale with a fixed jaw, and another jaw, with a pointer, that slides along the scale. The distance between the jaws is then read in different ways for the three types. The simplest method is to read the position of the pointer directly on the scale. When the pointer is between two markings, the user can mentally interpolate to improve the precision of the reading. Vernier, dial, and digital calipers can measure internal dimensions using the uppermost jaws in the picture at right , external dimensions using the pictured lower jaws, and in many cases depth by the use of a probe that is attached to the movable head and slides along the centre of the body.

Measuring and Quality Control

Mechanical pressure gauges Bourdon tube pressure gauges Differential pressure gauges Diaphragm pressure gauges Capsule element pressure gauges Test pumps Pneumatic pressure pumps Hydraulic pressure pumps Hydraulic table top test pumps Digital pressure gauges Hand-held instruments Hand-held instruments for pressure Oil deadweight testers Measuring Instruments. Here we are interested in electrical measuring instruments so we will discuss about them in detail. Deflection-type of pressure gauge 22 A digital instrument has an output that varies in discrete steps and only have a finite number of values; e. Basically there are three types of measuring instruments and they are. The matter presented here is prepared by the author for their respective teaching assignments by referring the text books and reference books. For different types of machinery and systems, various measuring tools, instruments and gauges are used on a ship. Mechanical Measuring Instruments Our company can avail from us a wide collection of Mechanical Measuring Instruments which is designed using high quality raw material.

A measuring instrument is a device to measure a physical quantity. In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units , and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty.

Here are some most commonly used mechanical instruments for measurement in industries. Learn all top instruments in our Mechanical Measuring Instruments online Course. Highlights of this blog in this Video. Vernier Caliper is a widely used linear measurement instrument with a least count of 0. It is used to measure linear dimensions like length, diameter, depth.


Measuring Instruments plays a vital role in the Engineering Workshop. The 10 types of Measuring Instruments and their uses are presented below. Print Friendly, PDF & Email Engineering Drawing Plays a crucial role in the life of Every Mechanical Engineering student because he has to bear that subject throughout.


List of measuring devices

Gross errors are caused by mistake in using instruments or meters, calculating measurement and recording data results. For measuring temperature we use different methods and devices. Vernier Callipers is used to measure the dimensions of the given specimen like diameter Outer Dia and Inner dia , length and depth etc. This information is then transmitted throughout the system by physical signals. The Instruments duty is to measure the given specimen according to the given dimensions.

List of electrical and electronic measuring equipment

There are various approaches to measuring instruments according to objectives and purpose.
