Metrology can be defined as the scientific study of
measurement. It consists of an understanding of units that are vigorous in
linking human activities. Modern Metrology is part of the French Revolution’s
political motive to regulate units in France when a space standard taken from a
usual source was proposed. It carried the creation of the decimal-based metric
system in the year 1795, beginning a set of standards for other different
measurements.
Normally, Metrology can be classified into 3 overlapping
activities, including the definition of units of measurement, the realization
of these units of measurement in practice, and linking measurements made in
practice to the reference standards. Each of them can be used in changeable
degrees by the three basic sub-fields of Metrology. All of these sub-fields are
scientific or fundamental metrology which is concerned with the establishment of
units of measurement, Applied, and Legal metrology.
Metrology and Inspection
As said, Metrology is all
about taking measurements. However, in machinery, it can be defined as taking
measurements as inspection.
Types of Metrology
Metrology is divided into three parts, including
• Industrial:
This is the main subject of this article.
• Scientific:
It is about creating standard units for measurements. It also consists of
research on how to enhance Industrial Metrology.
• Legal: It
is about economic measurements.
Metrology and Quality Control
Metrology and Quality Control go hand in hand. Quality
Control is all about ensuring that Requirements for a manufactured part have
been met.
The process of defining these tolerances is known as
Geometric Dimensioning and Tolerancing (GD&T).
Metrology offers the science, techniques, and precision
measuring devices that can be used to figure out if parts or specs of parts fit
within the tolerances as well as dimensions specified for the part.
Metrology Laboratory
When it comes to reaching the highest degrees of accuracy in
measurement, Metrology is conducted in a lab. The crucial characteristics of a
Metrology Laboratory are that it is temperature-controlled and clean, and Metrology
tools will well take care of. A Lab should be properly clean because
contaminants can get between the Metrology instruments and the parts and can affect
the accuracy of the measurement. Also, they should be temperature controlled
because both parts and instruments can change size based on the temperature of
a room. The most accurate measurements can be expressed in terms of a Standard
Reference Temperature.
Building Metrology Toolkit
There are three main measuring instruments, including
1. Digital
Calipers
2. Micrometer
3. Dial Test
Indicator with Magnetic Stand
All these measuring instruments serve different purposes
and taken together, you can do several measurements. It is important to buy good
quality versions of all these instruments.
Metrology Laboratory Equipment
Well, there are different types of metrology equipment and
instruments available that can be used for measurement. Height gauges, vernier
caliper, Surface Plate, sine bar, micrometer, Surface Plate, Roughness Tester,
depth gauges, slip gauge set, sine center, surface roughness tester, profile
projector, Dial Vernier Caliper, Co-Ordinate Measuring Machine, Digital Vernier
Caliper, Mounting Machine, and all types of measurement gauges are some of the
examples of Metrology Lab Equipment.
Today, there are many Metrology Lab Equipment
Suppliers that provide laboratory equipment and instruments to perform different functions. In addition to this equipment and
instruments, choosing equipment validation services is equally important to
boost integrity and avoid risks. Equipment validation services consist of
qualification and validation, including validation plans, installation, design,
operational, and performance qualifications. If interested, simply find a
reliable source to get Metrology Lab Equipment and Instruments.
