D.C Tachogenerator Principle

The D.C Tachogenerators is a type of electrical type’s tachogenerators which can also be used for speed measurement. The D.C

Mechanical torsion meter is used to measure torque developed by a machine. Principle of mechanical torsion meter When a shaft

Basic Principle Due to torque, an angular twist (angular displacement) occurs on the shaft between its ends. This angle of

Angular velocity is measured using devices called tachometers. Tachometers are instruments that measure angular speed by registering anyone of the

Principle of Moving Magnet type Velocity Transducer When a permanent magnet moves inside a coil, the change in the length

Principle of Moving coil Type Velocity Transducer A coil moves in a magnetic field according to the velocity applied. The

The main aim of a measuring system is to presnt the data in an understandable manner to the user /

A recorder is used to produce a permanent record of the signal that is measured. A record is used to

When a spring – mass – damper system is subjected to acceleration, the mass is displaced, and this displacement of

Torque Measurement using slotted Discs Due to the applied torque, there is a relative displacement between the two slotted discs.
