In an upcoming article, I will explain each instrument with its advantages and disadvantages. The above 6 different types of ammeter and voltmeter are covered. Because, it has high sensitivity and low power consumption. This type of instrument is very essential in communication circuits. The rectifier instrument is used for the measurement of the audio frequency of alternating current or voltage. This instrument is worked for the measurement of single-phase AC.
This instrument is working based on the induction motor principle. Thus, it can be worked as an ammeter or voltmeter or wattmeter, or energy meter. The induction instrument is suitable only for the AC measurement (i.e. Note: The electrostatic instrument can not be used as an Ammeter. It is used to measure the accurately low voltage (below the 30V). The quadrant type voltameter is suitable for the measurement of low voltage (up to 20 kV).Īnd multicellular type voltmeter is very sensitive over the quadrant type.
It works based on the existence of electric force between the charged objects or plates.īased on the construction and measuring capabilities, there are three types of electrostatic voltmeters.Īn attracted disc type voltmeter is suitable for the measurement of high voltage (above 20 kV). Also, it has the capability to measure the potential difference. The electrostatic instrument is a type of voltmeter which is used to measure the alternating as well as direct voltage. It is useful as a transfer instrument for calibration of measurement. It is basically used for the AC or DC measurements (current and voltage). The thermocouple instrument works as a temperature sensor. It has a simple construction and more accuracy in measurement. The hot-wire instrument is used for the AC as well as DC calibration. Mainly, there are two types of thermal instruments like as. This type of instrument is mostly used in the heating effect of the electric current. The thermal instrument has the same calibration for the alternating current and direct current. So, this instrument is very essential as a ‘ Transfer instrument‘ or ‘ Standard instrument‘. It is mainly used for DC measurements (current and voltage only).īut, the dynamometer is useful for both AC as well as DC measurements (such as current, voltage, and power).
The moving iron (MI) type instrument is worked as an indicating instrument. Classification of Ammeter and Voltmeterīased on the construction and working function, the ammeter and voltmeter are classified into the following parts.
