Tips: Characteristics of Hall current sensor with 4-20mA/0-20mA output signal
The use of current sensor with 0-5V output signal is limited when the signal needs to be transmitted remotely or the power grid interferes in the environment. It's because of the disadvantages of poor anti-jamming ability. While the current sensor with current output signal has been widely used for its high anti-interference ability.
The output range of the current output Hall current sensor is often 0~20Ma and 4~20Ma, and when the sensor outputs the minimum current and the maximum current, they are respectively represented the minimum and maximum rated output values calibrated by the sensor .
For the Hall current sensor with output 0~20Ma, we only need to select the appropriate buck resistance in the circuit design, it is suitable to convert the voltage on the resistor to digital signal through A/D converter directly, circuit debugging and data processing are relatively simple.
For the Hall current sensor with output 4~20Ma, the circuit debugging and data processing are more cumbersome. But the current sensor is capable of detecting wheather the current is in the normal range when the sensor is no signal, and to judge whether the circuit is faulty or not, so it is more commonly used.
Current sensors are AC/DC universal current sensors, with a low current measuring range from milliamp current 0.1mA to 5A. AC/DC current sensors adopt linear photoelectric isolation or modulation and demodulation principle, fast response, 0.5%FS high accuracy, good stability, small size, light weight, input current terminal connection, DIN rail installation. Isolated current sensors are widely used for AC sine wave current or DC bidirectional current measurement.
