Current transducers are vital components used in electrical systems. These devices are used to accurately measure the magnitude of a current passing through a load. The CR4420-20 current transducer is a device which converts electrical current into an output voltage signal. This output signal can then be used for monitoring, or further processing.

The CR4420-20 current transducer can be used for a variety of applications. It is commonly used in digital recording systems, to accurately measure the magnitude of the current within the circuit. It is also used in automotive systems, for applications such as engine ignition timing or speed control. Additionally, this transducer can be used to measure AC and DC current in renewable energy systems, such as solar photovoltaic (PV) and wind turbines.

The working principle of a CR4420-20 current transducer is based on the Hall effect. The Hall effect is the phenomenon where a transverse electric field is generated across a voltage-carrying conductor when exposed to a magnetic field. In the case of the CR4420-20, a primary coil is placed in the proximity of a permanent magnet. When current flows through the primary coil, it creates a magnetic field which interacts with the magnet’s magnetic field, generating a Hall voltage in the transverse direction. This Hall voltage is measured and used as an output voltage signal.

The CR4420-20 transducer is capable of measuring both AC and DC current. The signal conditioning circuitry inside the transducer allows it to accurately track the changing level of the current and output a corresponding signal. The device is available with several different sensitivity levels, which allow the device to measure currents ranging from 0-20mA to 0-100mA.

The CR4420-20 current transducer is a versatile device which can be used for a wide range of applications. Its ability to accurately measure both AC and DC currents makes it ideal for use in digital recording systems, automotive systems, and renewable energy systems. Coupled with its low power consumption and cost-effectiveness, the CR4420-20 current transducer is an attractive choice for any electrical system.
