Working Principle
Let's take a look at the working principles of DC current sensors to help you make a better choice.
| Sensor Type | Description |
| Hall Effect Type | Uses a Hall element to detect the magnetic field generated by DC current and converts it into a voltage signal. Offers non-contact measurement, electrical isolation, and bidirectional current sensing. |
| Shunt Type | Measures voltage drop across a precision resistor through which the current flows. Simple design, low cost, and high accuracy, but lacks electrical isolation. |
| Opto-Isolated Type | Converts current signal into a voltage signal and transmits it via optocoupler for electrical isolation. Ideal for industrial environments with high electrical noise. |
| Fluxgate Type | Detects magnetic field changes using a fluxgate sensor for very high accuracy. Commonly used in medical equipment and scientific instrumentation where precision is critical. |
