Modes of Measurement 2. Pressure or Temperature measurement 3. Measurement of rotating shaft Methods of Measurement Methods of Measurement Type of Method Technique to measure With contact Instrument is placed in contact with the object. For ex. Methods of Measurement Type of Method Technique to measure Comparative Based on the comparison of the value of a quantity to be measured with a known value of the same quantity. Null measurement Here, difference between measurand value and known value of same quantity with which it is compared is brought to zero.
Methods of Measurement Type of Method Technique to measure Substitutional Method Quantity to be measured is replaced by a known value of the same quantity, so selected that the effects produced in the indicating device by these two values are the same a type of direct comparison. Complementary Method The value of quantity to be measured is combined with known value of the same quantity. Ex: Volume determination by liquid displacement. Methods of Measurement Type of Method Technique to measure Transposition Quantity to be measured is first balanced by a known value and then balanced by an other new known value.
Value of quantity measured is first balanced by an initial known value A of same quantity, then measured by quantity is put in place of this known value.
Then, it is balanced again by another value B. If the position of element in equilibrium. Methods of Measurement Type of Method Technique to measure Coincidence Measurements coincide with certain lines and signals.
Callipers Deflection The value of the quantity to be measured is directly indicated by the deflection of a pointer on a calibrated scale Generalized Measurement System Generalized Measurement System Elements of measuring system 1.

This is incapability of system to faithfully measure signal in undistorted form.
If instrument is not precise, great difference in dimension measured again and again. Errors in flow measurement if flow- meter is placed immediately after a valve or a bend. Buoyant effect of the wind causes errors on precise measurement of weights by pan balance. This atmospheric condition can be maintain by air conditioning.
So it change the condition of the system. A ruler pressed against a body system resulting the deformation of the body. Parallax : These errors may arise when the pointer and scale not in same plane or line of vision of observer is not normal to the scale. Personal bias: Observer tendency to read high or low, anticipate a signal and read too iii.

Here is some most commonly used mechanical instruments for measurement in industries. Learn all top instruments in our Free 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.
Machinery onboard ships require regular care and maintenance so that their working life and efficiency can be increased, and the cost of operation, which includes unnecessary breakdowns and spares, can be reduced. For different types of machinery and systems, various measuring tools, instruments and gauges are used on a ship. Measuring instruments and gauges are used to measure various parameters such as clearance, diameter, depth, ovality, trueness, etc.
30+ Measuring Instruments for Mechanical Engineer
While it may be true that you can never have too many tools, some of the most useful tools you should have in your toolbox are not chromed or made with safety-grip handles. Some of these measuring tools are not cheap, but each performs at least one essential function that professional mechanics and manufacturers use on a regular basis and that you may someday also have a need for. Usually, you discover you need them right in the middle of a job, so it is a good idea to be preemptive and acquire these measuring tools as time and money permit.
The objective of the Japanese Standards Association - JSA - is "to educate the public regarding the standardization and unification of industrial standards, and thereby to contribute to the improvement of technology and the enhancement of production efficiency". Standards are named like "JIS X ", where X denotes area division, followed by four digits or five digits for some of the standards corresponding ISO standards , and the revision release year. Add standard and customized parametric components - like flange beams, lumbers, piping, stairs and more - to your Sketchup model with the Engineering ToolBox - SketchUp Extension - enabled for use with the amazing, fun and free SketchUp Make and SketchUp Pro.

Different Types of Mechanical Measuring Tools and Gauges Used on Ships
With a need to make quality products which meet design specified tolerances, a large number of firms, research and development centers, and school and college laboratories use measuring instruments that have high accuracy and precision. The special branch of science that deals with such instruments is known as metrology. Here we will look at the features and use of certain well known precision measuring instruments used for linear measurement. Vernier Caliper: It is an instrument used to measure internal and external dimensions of an object with a great accuracy. It is provided with inward jaws and outward jaws to facilitate the measurement.

Джабба облегченно вздохнул. Через шестьдесят секунд у него над головой затрещал интерком. - Прошу начальника систем безопасности связаться с главным коммутатором, где его ждет важное сообщение.
От изумления у Джаббы глаза вылезли на лоб. Похоже, она от меня не отвяжется.
Бринкерхофф и Мидж последовали за. - Смотрите! - сдавленным голосом сказала Мидж, махнув рукой в сторону окна. Фонтейн посмотрел на вспышки огней в куполе шифровалки.
Глаза его расширились. Это явно не было составной частью плана. - У них там прямо-таки дискотека! - пролопотал Бринкерхофф.
Ему вдруг страшно захотелось увидеть ее - сейчас. Прохладный ветерок кондиционера напомнил ему о жаре на улице. Он представил себе, как бредет, обливаясь потом, по душным, пропитанным запахом наркотиков улицам Трианы, пытаясь разыскать девчонку-панка в майке с британским флагом на груди, и снова подумал о Сьюзан. - Zumo de arandano, - с удивлением услышал он собственный голос.
