Current sensor, is a kind of detection device, can feel the information of the measured current, and can be detected and feel the information, according to a certain law to meet a certain standard of electrical signal or other required form of information output, in order to meet the transmission, processing, storage, display, recording and control of information and other requirements. Next, a detailed description of the role of the current sensor current sensor models and specifications.
First, the role of the current sensor
Application of current sensor in wind power generation: Wind energy, as a clean and renewable energy, has been paid more and more attention by countries around the world. The global wind energy is about 2.74×109GW, among which the available wind energy is 2×107GW, which is 10 times larger than the total amount of water energy that can be developed and utilized on Earth. Wind has been used for a long time -- mainly through windmills to pump water, grind surfaces, etc., but in the new century, people were interested in how to use wind to generate electricity, and how to maximize the amount of electricity produced. As the main detecting element, the current sensor plays an important role in it.
The role of current sensor
Two, the current sensor model and specification
1, current sensor type:
1, from the structure of open loop, closed loop. Generally, the open loop is better than the closed loop. The temperature compensation of the open loop is wider than that of the closed loop.
2, from the principle of zero flux current sensor, direct current sensor.
3, from the test current size is divided into large current sensor, small current sensor.
4. There are AC sensors and DC sensors from the test current types.
2, the rated current is generally from mA class to tens of thousands of A class. The usual is 4 to 20mA.
3, the output voltage generally has two specifications 0 -- 4V or 0.5-4.5 and 0 -- 5V(can be set by yourself)
The specific sensor will have to read their product manual.
