Current and voltage sensor is a kind of detection device, which can sense the information of the measured current, and transform the detected information into electrical signal that meets the requirements of certain standards according to certain rules, so as to meet the transmission, processing, storage, display, recording and control of information.

I , What are the characteristics of current and voltage sensors?

Look at Hefei Mycoil Technology Co.,Ltd to give you a detailed introduction.

Whether open-loop or closed-loop, the basic performance of current and voltage sensor is not very different. The basic advantages are: fast response time, low temperature drift, high precision, small size, wide frequency bandwidth, strong anti-interference ability and strong overload ability.

In order to automatically detect and display current, and to have automatic protection function and higher intelligent control when overcurrent and overvoltage occur, power supply technology with sensing detection, sensing sampling and sensing protection has gradually become a trend. Sensors for detecting current or voltage have emerged as the times require, and are subject to the majority of power supply designers.

II ,Applications of current and voltage sensors.

Current and voltage sensors can be used in household appliances, smart grids, electric vehicles, wind power generation and so on. Many of these magnetic sensors are used in our life, such as computer hard disk, compass, household appliances, etc. Current and voltage sensors can be divided into shunt, electromagnetic current according to different measuring principles. Transformers, micro electronic current transformers, etc. Electronic current transformers include Hall current and voltage sensor, Rokowski current and voltage sensor and Anyway frequency conversion power sensor (used for voltage, current and power measurement) for variable frequency measurement, and electromagnetic current and voltage transmission. Comparing with sensors, electronic current transformer has no ferromagnetic saturation, wide transmission frequency bandwidth, small secondary load capacity, small size and light weight, which is the development direction of current and voltage sensors in the future.
