The HDIC-C21 series current sensor is a measurement module that uses the Hall effect and open-loop measurement principle to convert the measured DC current into a DC current or DC voltage output in proportion. The primary and secondary sides are highly isolated. It has the characteristics of high accuracy, high linearity, high integration, small volume, simple structure, long-term stable operation and adaptability to various working environments. It is widely used in the system control and detection of electrical equipment in the power, oil, coal, chemical, railway, communication, and building automatic control industries.
The HDIC-C21 series is a Hall‑effect, open‑loop DC current sensor that converts measured DC current into proportional DC current or voltage output with high isolation between primary and secondary sides. It is designed for high accuracy, simple structure, long‑term stability, and can be used in power, petrochemical, mining, chemical, railway, communication, and building automation applications.
