Dimensional Metrology is the science of calibrating and using measuring equipment to determine the physical size or distance from an object. Inspection is a critical step in product development and quality control. Dimensional Metrology requires the use of a variety of physical scales to determine dimension, with the most accurate of these being laser interferometers and encoders. The realization of dimension using these accurate scale technologies is the end goal of dimensional metrologists.

The pressure measurement procedure is widely widespread within industrial processes and embraces several areas, such as Engineering metrology, steel, and metallurgical industries, Medical Industries, automotive, meteorological, aviation, among others.

The reliability of these measurements is related to trade, quality, health, and safety issues. In this way, a wrong measurement can create problems in the quality of the industrial process and even fatal accidents. Companies are looking for robust and reliable ways to monitor their process. For this monitoring to be effective, it is not enough to have installed several devices and pressure gauges in the plan of the factory. It is necessary to be sure that the measured value by the instrument is correct. And that’s where Metrology comes in.

According to the international vocabulary of general and fundamental terms of metrology (VMI), metrology is a “measurement science” and covers all aspects that influence a measurement process. With the process of production globalization, metrology has big importance as measurements are present in all decision making processes and cover the industrial, commercial, health, and environmental areas.

The calibration process of a pressure gauge is a complex activity and requires compliance with several requirements imposed by the related standards.

Mass:

The mass of an object is a fundamental property of the object; a numerical measure of its inertia; a fundamental measure of the amount of matter in the object. Definitions of mass often seem circular because it is such a fundamental quantity that it is hard to define in terms of something else. All mechanical quantities can be defined in terms of mass, length, and time. The usual symbol for mass is m and its SI unit is the kilogram. While the mass is normally considered to be an unchanging property of an object, at speeds approaching the speed of light one must consider the increase in the relativistic mass.

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the Newton. Density is mass/volume

Volume:

Volume refers to the amount of space that an object takes up. Liquid volumes are measured in literals or milliliters; solid volumes are measured in meters cubed or centimeters cubed — both of which are equal. To measure a solid object’s volume, scientists place the object in a container of water and then measure how many milliliters it displaces. They then convert that to centimeters cubed using the equation 1 mL = 1 cm^3.

Density :
Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Density is found by dividing the mass of an object by its volume.
Viscosity :
Viscosity is a fundamental characteristic property of all fluids. When a liquid flows, it has an internal resistance to flow. It is a measure of this resistance to flow or shear. It can also be termed as drag force and is a measure of functional properties of the liquid. Viscosity is a function of temperature and pressure. Viscosity is expressed two distinctive forms (a) Absolute or dynamic viscosity (b) Kinematic viscosity.

Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object’s acceleration is given by the orientation of the net force acting on that object.

Acoustics is defined by the Science of sound, including its production, transmission, and effects, including biological and psychological effects.

Mobile Force Measuring System (Push Pull Gauge)

It is basically a handheld instrument that contains a load cell, electronic part, software and display. For measurement of force during a push or pull test. It is also called as push pull gauge or force gauge. There are two kinds of force gauges i.e. mechanical and digital type.

Torque

Torque is the vector product of tangential force and length applied about a known centre of rotation.

Torque Measuring Device

A system comprising of an Electrical, Mechanical, Hydraulic or Optical Torque Transducers with associated instrumentation including the automated logging of data when part of the device Instrumentation can be a electronic instrument, a mechanical device is a scale and pointer system or a bourdon tube instrument.

Torque Generating Device

A device used to generate torque to a desired torque value. Typically this includes Torque wrenches, Torque screw drivers, Torque multipliers, Pneumatic or Electrical screw drivers, impulse or impact torque tools or wrench.

Rubber Hardness Tester

The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers.

Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials.
