Different Types of Standards of Measurement: A standard is physical representation of a unit of measurement. A known accurate measure of physical quantity is termed as a standard. These Standards of Measurement are used to…
Statistical Analysis of Measurement Data: The statistical analysis of measurement data is important because it allows an analytical determination of the uncertainty of the final test result. To make statistical analysis meaningful, a large number…
Dynamic Characteristics: Instruments rarely respond instantaneously to changes in the measured variables. Instead, they exhibit slowness or sluggishness due to such things as mass, thermal capacitance, fluid capacitance or electric capacitance. In addition to this,…
Types of Static Error: The static error of a measuring instrument is the numerical difference between the true value of a quantity and its value as obtained by measurement, i.e. repeated measurement of the same…
Errors in Measurement: Errors in Measurement is the process of comparing an unknown quantity with an accepted standard quantity. It involves connecting a measuring instrument into the system under consideration and observing the resulting response on…
Static Characteristics of Measuring Instruments: The Static Characteristics of Measuring Instruments are, in general, considered for instruments which are used to measure an unvarying process condition. All the static performance characteristics are obtained by one…
Introduction to Electronics Instrumentation: Introduction to Electronics Instrumentation which serves not only science but all branches of engineering, medicine, and almost every human endeavour. The knowledge of any parameter largely depends on the measurement. The…
Recent Trends in Electric Machines: Recent Trends in Electric Machines are neural networks, Artificial Intelligence, expert system, fibre communications and integrated electronics, hot superconductors and other new ceramic conducting and dielectric materials, magnetic levitation etc. should…
Types of Rotating Electric Machine: The Types of Rotating Electric Machine are namely the dc machine, the polyphase synchronous machine (ac), and the polyphase induction machine (ac). Three materials are mainly used in machine manufacture;…
Electric Generator Diagram: Electric Generator Diagram - Electricity does not occur naturally in usable form and it also cannot be stored in usefully large quantities. Therefore, it must be generated continuously to meet the demand…
