Current transducers have become increasingly important in industrial settings due to the changing demands of modern technology. They are used to detect and measure current, voltage, and other electrical parameters. One such current transducer is the CR4111-25, which offers accurate, repeatable measurements of electrical current. This article will discuss the application field and working principle of this transducer.

Application Field

The CR4111-25 current transducer is most commonly used in the manufacture of electronic components and systems. It is used to measure and monitor current in product tests and evaluations. This highly accurate transducer offers a low-cost solution for determining current without the need for costly and cumbersome laboratory equipment. It is also used in automated assembly and testing processes, as well as in motor performance measurements.

The CR4111-25 is also used in power distribution networks to monitor current consumption and control the flow of electricity. It is also widely used in industrial automation and process control applications, since it offers reliable readings over extended periods of time.

Working Principle

The CR4111-25 works by using an external monitoring coil to detect and measure the AC RMS (Root Mean Square) current. The transducer consists of two windings connected in series to a single winding forming a transformer with an internal impedance. These windings are connected to an electro-optic converter that converts the current into an electrical signal and amplifies it.

When the transducer is connected to the power line, the external monitoring coil will detect the AC power current. The external monitoring coil induces a voltage in the secondary winding, which is then converted to a current in the primary winding by a series of amplifiers and filters. This current is then converted to a digital signal that can be read by a host device.

The CR4111-25 can measure currents from 0.1 to 25A in both AC and DC modes. It is highly accurate and can detect current changes as small as 0.05%. It also offers repeatable measurements of current and can be used to detect power losses and surges.

Conclusion

The CR4111-25 current transducer is an effective and accurate instrument for measuring and monitoring current. It is used in many different industrial and commercial applications, including quality control, automated assembly and testing, and process control. The working principle of the transducer is based on the use of an external monitoring coil and an electro-optic converter to detect and measure AC and DC current. The transducer offers reliable readings over extended periods of time and can detect current changes as small as 0.05%.
