I , Working Principle of Current and Voltage Sensor

Current and voltage sensor is an electrical measurement sensor that converts a large current into a small voltage or current signal by Hall effect principle. The Hall electric quantity (voltage and current) sensor designed in practice usually amplifies the weak voltage signal into standard voltage or current signal through operational amplifier circuit. Let's take a look at Hefei Mycoil Technology Co.,Ltd to introduce the principle of current sensor for you.

Working Principle of Current and Voltage Sensor

Winding for current transformer

Before choosing, it is necessary to investigate and study all aspects related to the work of current and voltage sensors. To understand the characteristics of the measurement, such as the state and nature of the measurement, the measurement range, amplitude and frequency band, the measurement speed, time, accuracy requirements, overload amplitude and frequency, etc.

II , Advantages of Hall Current and Voltage Sensors

1.It can measure the current and voltage of arbitrary waveform, such as DC, AC, pulse, triangular waveform, etc. It can faithfully reflect the transient peak current and voltage signal.

II.High measurement accuracy: its measurement accuracy is better than 1%, which is suitable for any waveform measurement. Common transformer is an inductive component, which affects the measured signal waveform after being connected. Its general accuracy is 3%~5%, and it is only suitable for 50Hz sinusoidal waveform.

III.Fast response speed: the fastest response time is less than 1 us.

IV.The dynamic performance is good: the response time is fast, and can be less than 1 us; the response time of common transformer is 10-20 Ms.

V.Working frequency bandwidth: Signals in the frequency range of 0-100KHz can be measured.

VI.High reliability, long average trouble-free working time: average trouble-free time > 10000 hours.

VII.Good linearity: better than 0.1%

VIII.Strong overload capability and wide measurement range: 0 - tens of amperes to tens of thousands amperes.

IX.Small size, light weight, easy to install.
