    50A to 1500A Hall Effect Current Sensor Details

    Tips: The advantages of Hall effect current sensor

    1. 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.
    2. Good linearity: Hall current sensor has good linearity and is better than 0.1%.
    3. 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.
    4. 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.
    5. 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.
    6. 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.

    Solve the problem of current sensor
    Thank you. I did double-check the zero point today and it was at 3mA. I adjusted it with the pot so that it was at 4mA. But now it's showing 92mA on the output end.
    I tried using the span pot to change the output, but moving the span pot all the way from left to right doesn't change the output at all. Would you say the sensor is probably burned out, since the 2nd pot doesn't have any effect on the output?

    If the output of the adjustment potentiometer does not change, we think that your sensor may be burnt out.
    Please take a video or photo showing us your issue, so that we can further help you to solve the problem.
    Thanks for your understanding. You can send us the large video file via wetransfer.com.
    Why current sensor is outputting too much current on a line
    We have 2 of these, in the 200 amp range: https://www.ato.com/dc-current-sensor-50a-to-1500a
    I installed one of them a few months ago for one of our large solar pumps, which should be drawing 90 amps DC from the solar panels. It has been working fine. I tested it yesterday with a multi-meter and it was outputting 13mA.
    Recently I installed the other one on a larger solar pump which should be drawing about 120 amps. For some reason it is always outputting more than 20mA. I was seeing 50mA on it yesterday.
    I removed the DC current sensor from the smaller pump and installed it on the DC line for the larger pump, and that one was showing me 35 mA on that line, even though a clamp meter was showing me 119 amps DC.
    Yesterday I ordered a 300 amp version of that current sensor from your website, just in case I needed a bigger range.
    Do you have any guesses as to why it's outputting too much current on a line that should be a maximum of 120 amps on the sensor that can read up to 200 amps?

    1. Did you adjust the potentiometer on the Hall when you changed the larger solar pump? Please check if the zero point of the DC current sensor is 4mA when the power is only applied but no current is applied.
    2. You change the sensor on the 90A small pump to the 120A pump, please check whether the change of the sensor output is a linear change, and if the function of the linear change sensor is correct.
    3. If the sensor shows a particularly large 50mA, please recheck the wiring. The normal output should be a fixed value without functional variation.
    Do you have a recommended validation method for how to verify the sensor is measuring the current properly using the entire range of 0-400A?
    I have bought the 0-400A DC current sensor, and I require a way of validating the sensor. Do you have a recommended validation method for how to verify the sensor is measuring the current properly using the entire range of 0-400A?

    What data do you want to validate with this current sensor?
    Is it the corresponding relationship between the output signal and the input range of the current sensor?
    Normally, our current sensor has been calibrated before shipping out, you can use it directly.  
    You can also use a high-precision digital current clamp meter or find a third-party measurement agency for validation.
    Can DC current sensors be calibrated?
    Can your DC current sensor be calibrated? Is that what the adjustment screws are in blue?

    This unit does not need to be calibrated, it should be used directly after purchase as it is already well calibrated before shipping out. The two potentiometers on the sensor are for the factory calibration.
