Current transducers are electronic devices used to measure the current flowing through a conductor. They are usually connected to the circuit via a pair of conductors, one each for the positive and negative current flow. The transducer measures the magnitude and direction of current, and converts this into a proportional analog or digital signal. This signal is then used for purposes such as monitoring, protection, and control of the circuit, as well as for data logging or display.

The CT 0.2-P is a current transducer designed for highspeed operation and accuracy. It is capable of measuring very small currents, down to 0.2 A, and can withstand temperatures up to 100°C. The CT 0.2-P is also able to protect itself from short-term overloads, and is able to detect high frequency noise.

The working principle of the CT 0.2-P is based on the Hall effect. The Hall effect is a phenomenon where a magnetic field is produced perpendicular to an electric current flowing through a conductor. This magnetic field is then detected by two Hall probes, located on each side of the current conductor. The signal from the Hall probes is then amplified, and converted into an AC voltage signal.

The signal is then filtered to remove any high frequency noise, and then sent to a differential amplifier. This differential amplifier amplifies the signal, and converts it into a DC voltage, which is proportional to the current flowing through the conductor. This output signal is then sent to the analog-to-digital converter, which converts it into a digital signal for output or processing.

The CT 0.2-P has a wide range of applications. It can be used in motor drives, power supplies, energy meters, and other industrial and laboratory equipment. It can also be used in automotive and robotics applications, to measure and control current. It is also suitable for medical and safety applications, providing accurate and reliable current measurements.

In summary, the CT 0.2-P current transducer is a versatile and accurate device designed for a wide range of applications. Its working principle is based on the Hall effect, where an electric current produces a magnetic field, which is then detected and converted into a proportional voltage signal. This signal can then be used for monitoring, protection, and control of the circuit.
