Photoelastic analysis explained
Photoelastic analysis is a technique used to study stress distribution in materials, particularly in transparent materials, by observing the light patterns that are produced when the material is subjected to mechanical stresses. The principle is based on the fact that stresses within a transparent material cause changes in its refractive index, which can be observed…

Strain measurement explained
Strain Measurement in Engineering Strain measurement is fundamental in engineering for assessing material deformation under load. Strain () is the relative deformation of a material and is defined as: where: 1. Strain Gauges The most common method for measuring strain is the use of resistive strain gauges, which rely on the principle that a material’s…

Proximity sensors explained
Proximity Sensors: An Overview Proximity sensors are devices used to detect the presence or absence of an object (target) without making physical contact. These sensors are widely used in industries for automation, safety, and process control. Based on their operating principles, proximity sensors can detect objects through various means such as electromagnetic fields, sound waves,…

How do pressure gauges work?
Pressure gauges are instruments designed to measure and display the pressure of a fluid (liquid or gas) within a system. Here is a detailed explanation of how pressure gauges work: Types of Pressure Gauges 1. Bourdon Tube Gauges Mechanism: Operation: 2. Diaphragm Gauges Mechanism: Operation: 3. Capsule Gauges Mechanism: Operation: 4. Digital Pressure Gauges Mechanism:…
