## What is a Stroboscope? - Stroboscope Tachometer & its Working Principle

What is a Stroboscope? A stroboscope or strobe is an instrument that works on the phenomenon of stroboscopic effect. It creates a stop motion effect of a rotating object by flashing a high-intensity light on it. This appearance …

## Measurement of Linear Velocity Using Velocity Transducers

The speed (how fast is object moving) and direction of motion of an object or rate of displacement covered by an object traveling along a straight path is known as the Linear Velocity. Most of the linear velocity transducers work…

## Measurement of Angular Velocity Using Digital Methods

The electromechanical tachometers (dc and ac tachometer generators) are suited for measuring angular velocity up to 10000 rpm. For measurement of high speeds effectively, various digital methods are employed, where there is no ph…

## Applications of LVDT - Measurement of Displacement, Pressure & Acceleration

A Linear Variable Differential Transformer (LVDT) is an electrical transducer or sensor used for the measurement of physical quantities like displacement, force, pressure, acceleration, etc. It works on the principle of mutual in…

## Piezoelectric Transducer Applications - Measurement of Force, Pressure & Acceleration

The phenomenon of the piezoelectric effect in piezoelectric transducers can be used for the measurement of various physical quantities like force, pressure, acceleration, etc. It is an active transducer (doesn't need any exte…

## Piezoelectric Transducer - Working Principle, Theory & Applications

What is Piezoelectric Transducer? The piezoelectric transducer is an active transducer that converts physical quantity (force or pressure or stress) into an electric potential. The piezoelectric transducer consists of a piezoele…

## Electrical Tachometer - Construction & Types | DC & AC Tachometer

The tachometer is a measuring instrument used for measuring the angular (rotary) velocity of a rotating object. They measure rotational speed in revolutions per minute (RPM). It is important to measure the rotating speed of machi…

## What is Photoelectric Transducer? - Definition & its Types

What is Photoelectric Transducer? The photoelectric transducer is a light-sensitive device used to convert light energy into electrical energy. It is made up of semiconductor material that emits electrons when a beam of light fa…

## Difference Between Photovoltaic (PV) and Photoconductive Transducers or Cells

The photoconductive and photovoltaic (PV) transducers are the photoelectric transducers that convert light energy into electrical energy. Both are made up of semiconductor material which absorbs light energy and energizes the el…

## Types of Strain Gauges - Bonded & Unbonded Strain Gauges

The strain gauge is a transducer used to measure strain and associated stress in experimental stress analysis. When a metal wire (or conducting wire) is stretched or compressed, its length and diameter change due to which the res…
