58彩票There are many types of current sensors, and there are also many manufacturers with their own research and development capabilities and manufacturing lines. However, there are very few specific high-precision current sensors to choose from. So how to choose a suitable high-precision current sensor?

Surface mounted high-precision current sensor

Installation of high-precision current sensors on busbars

At present, high-precision current sensors are imported from Switzerland's LEM (through the acquisition of Danish Danfysik), Denmark's Danisense (a new company established by members of the former LEM's magnetic modulation current sensor research and development team), and the Netherlands' HITEC (focusing on the field of particle accelerators). China started relatively late in this area, but there has also been great progress in high-precision current sensors. Currently, only Galaxy Electric's CS series zero flux current sensor (through the acquisition of Plexus) has in-depth research in high-precision. So currently, there are not many brands to choose from for high-precision current sensors. (You can take a look at Weikewei Technology's high-precision current sensor)

2、 High precision current sensor accuracy

58彩票HITEC in the Netherlands focuses on the field of particle accelerators, which has a relatively small market and is not considered. The accuracy of three other manufacturers, including CS series zero flux current sensors, has reached the ppm level. The IT series current sensor from LEM in Switzerland has a maximum accuracy of 3ppm, while the CS series zero flux current sensor and Danisense have a maximum accuracy of 1ppm.

3、 High precision current sensor range

58彩票The IT series flux gate current sensor from LEM in Switzerland has a measurement range of 12A~24000A, the Danish Danisense flux gate current sensor has a measurement range of 200A~8000A, and Galaxy Electric's CS series zero flux current sensor has a measurement range of 1mA~25kA.

4、 Other parameters

Choosing a suitable high-precision current sensor also requires considering specific requirements such as sensor bandwidth, temperature drift coefficient, linearity, output signal, and even installation method, power supply, etc. These parameters are also factors that affect the selection.

Overall, there are more factors to consider when choosing a high-precision current sensor, and the price is also relatively expensive. It is important to understand the requirements as clearly as possible before purchasing in order to find a suitable high-precision current sensor.

58彩票Of course, we hope you can consider Weikewei Technology's high-precision current sensor. If you have any requirements for high-precision current sensors, please contact Weikewei Technology directly or make a phone call directly.
