The book is divided into two parts that explain the topics Measurements and Instrumentation.

6.4 Electrical Measuring Instruments

The instruments used to measure any quantity are known as measuring instruments. If the instruments can measure the basic electrical quantities, such as voltage and current are known as basic measuring instruments. As the name suggests, voltmeter is a measuring instrument which measures the voltage across any two points of an electric circuit. The units of voltage are volt and the measuring instrument is meter. We can classify the voltmeters into the following two types based on the type of voltage that it can measure. As the name suggests, DC voltmeter measures the DC voltage across any two points of an electric circuit. A practical DC voltmeter is shown in below figure.

The instrument used for measuring the physical and electrical quantities is known as the measuring instrument. The term measurement means the comparison between the two quantities of the same unit. The magnitude of one of the quantity is unknown, and it is compared with the predefined value. The result of the comparison obtained regarding numerical value. This instrument is suitable for measuring the static and stable condition because the instrument is unable to give the response to the dynamic condition. The electronic instrument has quick response time.

Electrical measuring instruments and measurements

Ammeters are always connected in series with the circuit to be tested. It is obtained by multiplying the current in amperes by the time in hours during which current flows. For example, a battery which provides 5 amperes for 20 hours is said to deliver ampere - hours. One ampere is equal to a current flow of one coulomb per second. Apparent power is the product of the rms voltage and the rms current.

Facebook Twitter. An analog instrument is one in which the output or display is a continuous function of time and bears a constant relation to its input. Analog instruments find extensive use in present day applications although digital instruments are increasing in number and applications. The areas of application which are common to both analog and digital instruments are fairly limited at present. Hence, it can safely be predicted that the analog instruments will remain in extensive use for a number of years and are not likely to be completely replaced by digital instruments for certain applications.

Electronic Measuring Instruments

Electrical instruments are instruments that use the mechanical movement of electromagnetic meter to measure voltage, power, current… Electrical technicians require electrical measurement equipment to check the electrical activity and to detect the presence of voltage or current. By using this instrument we can measure electrical parameters such as voltage, frequency, current, power factor, and resistance. Electrical measurements are depended upon either current or voltage while measuring the frequency we will be measuring the frequency of a current signal or a voltage signal. Electrical instruments are classified according to the electrical quantity or the measured characteristics.

Here, I am describing the major concepts of electrical measuring instruments in detail. Before starting any electrical or electronics device installations or studying electrical practical, we should know about the measurements and its measuring instruments. This basic knowledge will help you throughout your electrical and electronics engineering.

 Но… Послышался щелчок положенной на рычаг трубки. Беккер беззвучно выругался и повесил трубку. Третья попытка провалилась. Он помнил, что сказал Клушар: немец нанял девушку на весь уик-энд. Беккер вышел из телефонной будки на перекрестке калле Саладо и авениды Асунсьон.

Пистолет выпал из его рук и звонко ударился о камень. Халохот пролетел пять полных витков спирали и замер. До Апельсинового сада оставалось всего двенадцать ступенек.

 Что это. Стратмор вздохнул: - Двадцать лет назад никто не мог себе представить, что мы научимся взламывать ключи объемом в двенадцать бит. Но технология не стоит на месте. Производители программного обеспечения исходят из того, что рано или поздно появятся компьютеры типа ТРАНСТЕКСТА.

Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир. Да, я была с ним слишком сурова, - подумала Сьюзан. Ее мысли были прерваны внезапным звуковым сигналом входной двери Третьего узла.
