There are many types of electrical instruments, which are divided into four categories: indicating instruments, comparing instruments, digital meters and smart meters. The following small series will introduce you to the four types of electrical instruments, to help you better understand the types of these four major electrical instruments:
First, the indicator
Features: It can be converted into the mechanical deflection angle of the movable part of the meter and directly indicates the measured size through the indicator. It is also called direct reading instrument.
Classified according to working principle: There are mainly magnetoelectric instrument, electromagnetic instrument, electric instrument and induction instrument. In addition, there are rectifier meters, ferromagnetic electric meters, and so on.
Typical instrument: mounted instrument, portable instrument
Second, the comparison instrument
The characteristics of the comparison instrument: In the measurement process, the measured size is compared with the standard standard of the same type, and then the measured size can be determined according to the comparison result.
Comparison instrument classification: DC comparison instrument and AC comparison instrument. The DC bridge and the potentiometer belong to the DC comparator, and the AC bridge belongs to the AC comparator.
Typical instrument: comparative DC bridge
Third, the digital instrument
The characteristics of digital meters: digital measurement technology is used, and the measured size is directly displayed in digital form.
Classification of digital meters: commonly used are digital voltmeters, digital multimeters, digital frequency meters, and so on.
Typical instrument: digital voltmeter
Fourth, smart meters
Features of the smart meter: Using the control and calculation functions of the microprocessor, the instrument can realize functions such as program control, memory, automatic correction, self-diagnosis fault, data processing and analysis and calculation.
Classification of smart meters: Smart meters generally fall into two categories: one is a smart instrument with a microprocessor; the other is an automatic test system.
Typical instrument: digital storage oscilloscope
