The HIA-C01 series current sensor is a measurement module that converts the measured current into a proportional current or voltage output using the Hall closed-loop (magnetic balance) principle. It features high accuracy, high linearity, high integration, small size, simple structure, long-term stable operation, and adaptability to various working environments. This current sensor is widely used in electrical equipment system control and detection in industries such as power, oil, coal mining, chemical, railway, communication, and building automation.
