Current transducers are electrical devices commonly used to measure the magnitude of an electric current or to measure the peak values of alternating current. CR5211-2 is one of the popular current transducer products in the market. It integrates advanced technologies to provide superior current measuring performance and output. This article will provide an in-depth analysis of the application field and working principle of CR5211-2 current transducer.

Application field

CR5211-2 provides a wide range of application for accurate and reliable current measurement. It is widely used in electric power system, renewable energy system, electrical motor control system, and industrial process control system. In the power system application, it can be used to monitor and control the distribution line, main incoming power, generator output, and transformer output current. In the renewable energy system, it can be used to measure the current of photovoltaic array and wind turbine. In motor control system, it is used to measure the motor current for automatic control and protection application. In industrial process control system, it is used to accurately measure process current for monitoring and controlling the process.

Working principle

The working principle of CR5211-2 current transducer is based on the principle of the Hall effect. It uses a Hall element as the sensing element. When a current passes through the Hall element, an electric field is generated in the Hall element, which results in a voltage at the output. This voltage is used to measure the magnitude of the current passing through the Hall element. The Hall element is very sensitive to the magnetic field, so it can measure very small current.The CR5211-2 also uses an amplifier circuit to amplify the voltage generated by the Hall element. This voltage is then used to drive an output circuit which can provide an accurate voltage output. This output voltage can be used to display the input current. The CR5211-2 also uses an over-voltage protection circuit to protect the sensor and output circuit from over-voltage.

Conclusion

CR5211-2 is a popular current transducer in the market. It uses the Hall effect as the sensing element and an amplifier circuit to measure and display the input current. It is widely used in electric power system, renewable energy system, motor control system, and industrial process control system. With its excellent performance, it is a reliable and accurate current measuring device.
