Current transducers are devices used to measure alternating or direct current purposes. They come in many forms, including Hall Effect transducers, current transformers, galvanic transducers, and Rogowski coils. One particular type of current transducer is the CR4420S-10. In this article, we will discuss the application field and working principle of this device.

The CR4420S-10 current transducer is designed for use in high current applications. It measures currents ranging from -1000 to +1000 milliamps with 0.1 milliamp resolution. It has a long life and low maintenance requirements, meaning it can be used in many different applications. The current transducer is well suited for measuring a range of low to high current loads in industrial, commercial, and residential environments.

The CR4420S-10 has its own built-in power supply, allowing for easy installation and maintenance. The unit is also equipped with an adjustable current range, allowing it to accurately measure a range of current flows. Additionally, the built-in microprocessors help monitor the current state, meaning the device can operate accurately in both ideal and non-ideal environments.

The CR4420S-10 uses the Hall effect principle as its working principle. The Hall effect is a magnetic sensing principle which uses the Lorentz force (the force generated when a charged particle is placed in a magnetic field) to measure current flow. A small voltage (Hall Voltage) is generated when a current-carrying conductor (wire) is placed perpendicular to a magnetic field. This Hall voltage is related to the magnetic field intensity and the current flowing through the wire.

The CR4420S-10 measures the Hall Voltage generated by the current flow and uses an on-board circuit to calculate the current flowing through it. By measuring the Hall Voltage generated by current flow, it can detect any changes in the current orientation and therefore measure currents in both ac and dc applications.

In addition to its Hall effect sensor, the CR4420S-10 also has an onboard shunt resistor. The shunt resistor is used to provide additional current measurement accuracy. By measuring the voltage across the resistor, it can accurately measure currents from small values up to the full range of the device.

The CR4420S-10 is an ideal current transducer for many applications. It is a reliable current measurement device, allowing for accurate measurement of alternating and direct current flows in both ideal and non-ideal environments. With its onboard power supply and adjustable current range, it is a great choice for industrial, commercial, and residential environments.
