Current Transducers

CR4150-5 is a type of current transducer. It has a wide range of application fields and a special electrical working principle.

Application fields

CR4150-5 transducer provides the field with various options for monitoring currents in AC or DC circuits. It can be applied in electrical equipment, distribution boards, electrical wiring and control systems, as well as other devices with unprotected or protected electrical power connections. As a result, CR4150-5 transducer can be used in a wide range of industrial applications, such as electrical vehicles, communication systems, power control systems, medical industry, safety systems, electric furnaces, electromechanical systems, etc.

Besides, CR4150-5 current transducer also has wide application in rail transport. It can be used to measure and analyze the current in multiple areas, such as locomotives, cabins, Passenger cars, and DC/AC networks. The transducer can guarantee a reliable measurement on rail transport in order to monitor any anomaly and provide with warnings, which can help to detect faults.

Working Principle

The CR4150-5 transducer works in a contactless electrical manner. It is based on the principle of the electromagnetic induction law. This implies that the transducer has an electrical primary circuit which generates a primary magnetic field or flux (H), and a secondary electric current, which is proportional to the applied current in the primary circuit. The current in the secondary circuit has an amplitude and a phase shift, depending on the amount of current in the primary circuit. Furthermore, the output current in the secondary circuit generates a secondary magnetic field (H2), according to the converted voltage across the secondary coil.

The CR4150-5 current transducer is able to process the secondary current accurately. This is realized by a half bridge diode rectifier circuit, which is connected in parallel with the secondary circuit. The rectifier circuit rectifies the output signal of the secondary circuit in order to eliminate the phase shift between the primary and the secondary coils. The output of the secondary circuit is also amplified. This is done in order to increase the sensitivity of the transducer. Finally, the amplified signal is compared to the reference signal, which is generated by a voltage source circuit. This comparison is used to calculate the current in the primary circuit.

Conclusion

In summary, the CR4150-5 current transducer is a useful instrument for measuring and analyzing current in various applications. Its accuracy and reliability can help to detect any anomaly and provide warnings, giving personnel in the industry more confidence with their decision making. The transducer works based on the principle of electromagnetic induction law, while its half bridge diode rectifier circuit and voltage source circuit are used to accurately process and measure the current.
