Introduction – Measuring
and Metallurgical instruments are the instruments/equipments that are used to
measure the different physical quantities like Surface quantities, Hardness,
Tensile strength, Roughness & Thickness of the real world metallic &
non-metallic objects or bodies. In industrial engineering, production and
quality assurance, measuring instruments are used to obtain the physical
quantities of specimen objects or products for their true value & quality
control. The measuring instruments are not limited to the above mentioned
objectives but also there are lots of things that you can measure with different
measuring devices / instruments.
Calibration of measuring instruments – Calibration is done to compare the
measured values by measuring devices/instruments to the calibrated
international standards. These
comparisons of the measured values are done to find the stability,
reproducibility, precision & accuracy of the measuring instruments.
Following would be the outcomes of the calibration of a measuring instrument-
a. No error in the
device- The device given the exact value in an experiment as that
of the standard value.
b. Significant error but no adjustment done
c. An adjustment made to correct the error to reach an
acceptable level

Measuring & Metallurgical instruments in different industries
& society- Different
measuring instruments are used by different industries, Institutions and
organizations as per their need. By the way almost all the dimensional
measuring instruments
are used by the mechanical or physical industries.
Automotive
industry
In
the automotive industry measuring instruments are required for conducting
inspection, measurement, and quality checks for various components and parts.
The automotive industry has been increasingly using optical measurement systems and
coordinates measuring machines instead of the conventional strain gauges,
accelerometers, transducers, and extensometers for improving the safety and
comfort level of vehicles. Dimensional metrology or measurement equipments are
crucial for automotive industry as designing and styling play an important role
in the automotive industry.
Aerospace and Defense
Metrology/Measuring
instruments play
crucial role also in Aerospace and Defense industry as it is one of the highly
competitive industries/market where products performance and their quality is
very important for market success. Environmental concerns and Regularity
changes are the serious challenges for this industry. As this industry have to
use new construction materials, production techniques such as additive
manufacturing & advanced machining.
Manufacturing/Production
Nowadays, manufacturing industries are having huge
demands of manufacturing more products in a shorter time along with enhanced
quality demands and standards. In this situation, unstable & disturbing
processes and low precision quality control can cause serious quality problems
or production failures. Therefore manufacturing companies are facing huge
pressure to remain competitive in their respective markets as they have to
optimize and control all of their processes very effectively &
economically. Again affordable high precision metrology/measuring equipments are
required to meet these challenges.
Benefits of using high precision measuring instruments – As you
know quality control have become one of the most important roles for the
production in all industries, the industries should move towards the use of
high precision metrology equipments with latest technologies for better control
on quality, time consumption and economical performance. Measuring instruments are
available in the market with –
A. Higher
stability
b. High
accuracy
c. Digital
& Automatic functions that make them easy to use and save time of the
industry.
The
product development and process validation are directly depending on the high
precision measuring instruments while performance of a company & its
existence or stability in the market is indirectly dependent.
Quality control is
the key to better performance
