Current transducers are a type of instrument that measure the signal of current in an electrical system. This measurement is then used to determine the current intensity of a circuit. The CR4220-5 is a model of current transducer that has become widely popular due to its superior performance and reliable operation.

The CR4220-5 is a stationary-type, four-to-five wire current measuring device that works on the principle of magnetic induction. It is classified as a current transformer and is built to measure both AC and DC currents. A current transformer is an electronic device that allows for measurement of an electric current through open loop or non-invasive measurement. The CR4220-5 can measure AC and DC currents of up to 60A.

The core of the CR4220-5 is made up of several laminations of magnetic materials, such as steel, iron, or metal alloys. These laminations shield the core from any external magnetic fields that may interfere with its operation. A primary winding is wound around the core, and a secondary winding is wound around the primary winding. When current flows through the primary winding, a magnetic field is generated and induces a secondary current in the secondary winding. This secondary current is proportional to the primary current, and the magnitude of the current is determined by the number of turns in the primary winding.

The CR4220-5 has two parts: the primary unit and the secondary unit. The primary unit houses the core, primary winding, and a sense resistor. The secondary unit contains the secondary winding and the output terminals. The primary winding in the primary unit acts as a conductor, allowing current to flow through it. The sense resistor in the primary unit has a rating of 250 Ohms and can be used to sense the primary current in the circuit. This sensed current is then converted into a voltage signal via the secondary unit, which can then be read from the output terminals.

The CR4220-5 sensor is connected in series with the circuit and measures the current in the circuit. This measured current is then transmitted as a voltage signal to the output terminals. The primary and secondary windings are specially designed and optimized to ensure accurate and reliable operation. The accuracy of the sensor is within a range of +/- 0.35A, depending on the sensing mode.

The CR4220-5 is a versatile current transformer that can be used in many different applications. It can be used to measure current in smaller circuits such as automotive systems or larger industrial circuits. It is also used to measure the power draw of appliances and other electrical systems. The device is also used in electrical inspection and maintenance as it provides an accurate reading of the current flowing through a circuit.

In conclusion, the CR4220-5 is a reliable and accurate current measured device designed specifically for the measurement of AC and DC currents. Its robust design and reliable operation make it an ideal choice for a wide range of applications. Its superior performance and accuracy make it an invaluable tool for today’s engineers, technicians, and electricians.
