Instrumentation engineering is the engineering specialization focused on the principle and operation of measuring instruments that are used in design and configuration of automated systems in areas such as electrical and pneumatic domains, and the control of quantities being measured.
Instrumentation and control engineering is a vital field of study offered at many universities worldwide at both the graduate and postgraduate levels. This discipline integrates principles from various branches of engineering, providing a comprehensive understanding of the design, analysis, and management of automated systems.
Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter: Measures the potential difference between two points in a circuit. (Includes: DVM and VTVM) VU meter: Measures the level of AF signals in Volume units Cathode Ray Oscilloscope (CRO)
A wide range of instrumentation is used by electrical engineers. For simple control circuits and alarms, a basic multimeter measuring voltage, current, and resistance may suffice. Where time-varying signals need to be studied, the oscilloscope is also an ubiquitous instrument.
Instrumentation amplifiers are used where great accuracy and stability of the circuit both short- and long-term are required. Although the instrumentation amplifier is usually shown schematically identical to a standard operational amplifier (op-amp), the electronic instrumentation amplifier is almost always internally composed of 3 op-amps ...
series and parallel circuits Electrical circuits where current passes through multiple elements either one after the other, or side by side, like the rungs of a ladder, or both. shaded-pole motor An alternating current single-phase motor that produces a rotating magnetic field by a turn of wire around part of a field pole. shaft voltage
It is one of the most common I/O interfaces present in instruments and is designed specifically for instrument control applications. The IEEE-488 specifications standardized this bus and defined its electrical, mechanical, and functional specifications, while also defining its basic software communication rules.
High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
