Current Transducers

Current transducers are devices that measure current flow on a certain circuit without the use of a physical connection to that circuit. This makes them ideal for applications where physical contact with a dangerous circuit is not possible or desirable. The CR4220-25 is one such device and is designed for power and energy monitoring applications.The CR4220-25 is a measurement device that operates on the principle of Hall effect. Hall effect is a phenomenon where an electrical potential is produced in a conductor due to the application of a magnetic field. This device is designed to measure the current flow in a circuit without the need to physically connect to it. It also works with a wide range of AC and DC currents.The CR4220-25 is mainly used for power and energy monitoring applications. Its ability to measure currents without the need to make physical contact with the circuit provides a safe and reliable way of monitoring power usage and energy consumption of an electrical system. This saves time and money by eliminating the need for additional disconnected current transformers.The working principle of the CR4220-25 is based on the Hall effect. This effect produces an electrical potential in a conductor when a magnetic field is applied to it. This potential is proportional to the current flow in the circuit, and thus can be used to calculate the current.The CR4220-25 has an integrated Hall effect sensor that can detect the position of a permanent magnet placed on a rotating platform. The Hall Effect sensor then detects the changing magnetic field from the magnet and produces a voltage that is proportional to the current flow in the circuit. This voltage is then used as an input signal to a microcontroller to calculate the current flow in the circuit.The device also comes with an integrated LCD display. This display shows the reading in real-time, which makes it easier to track power usage and energy consumption of an electrical system. It also features an adjustable alarm mode that can be used to alert the user when the current exceeds a certain threshold.Overall, the CR4220-25 is an ideal device for power and energy monitoring applications. Its ability to measure the current without having to make physical contact with the circuit makes it safe and reliable, while its integrated LCD display allows for easy tracking of power usage and energy consumption. Finally, its adjustable alarm mode ensures that the user is alerted when the current exceeds a certain threshold.
