Tips: The advantages of Hall effect current sensor
- High accuracy: The precision of Hall effect current sensor is high, the accuracy is better than 1.0%FS in the operating temperature zone, some can reach 0.5%FS, and this accuracy is suitable for any waveform measurement. While the accuracy of general current transformer is generally 3~5%FS, and is only suitable for 50Hz sine wave.
- Good linearity: Hall current sensor has good linearity and is better than 0.1%.
- Dynamic performance: The Hall effect current sensor dynamic performance is very good. Some of the response time can be less than 5us, tracking speed di/dt is higher than 50A/μs, This excellent dynamic performance provides a key basis for improving the performance of modern control systems. Compared with this, the response time of ordinary current transformer is 10-12ms, which cannot meet the needs of the development of industrial control system.
- Working frequency band: The Hall current sensor has a wide working frequency band and the accuracy is 1% in the 0-100kHz frequency range. The accuracy is 0.5% in the 0-5kHz frequency range.
- Measuring range: The Hall current sensor measurement range is large. Hall sensor current measurement is up to 50000A, can measure AC and DC current, it also has no special requirements for waveform. AC current transformers can only measure AC current, and the frequency must be rated frequency, such as 50Hz. The error of current transformer for 60Hz measurement is relatively large. The output signal cannot be directly connect to the electronic detection circuit.
- Overload capacity: The Hall effect current sensor’s overload capacity is very strong, when the original current overload, the current sensor reached saturation condition, it can be automatically protected, even if the overload current is 20 times to the rated value, the current sensor will not be damaged.
In addition, Hall sensor also has the advantages of small size, light weight, high sensitivity and strong anti-electromagnetic interference ability. This makes Hall sensors be used in the industrial field extensively, and the market space is gradually increasing.
