Current transformer and measuring transducer in a single device

In systems designed for automatic monitoring and control of various technological processes, it is often necessary to measure alternating current and obtain a standard 4-20 mA DC signal at the output.

Typically, this requires connecting a current transformer and measuring transducer in series, such as the RISH Xmer series transformer and Rish CON-CA transducer.

However, RISHABH offers a simpler and more effective solution - Rish CT Ducer transformer-transducer combines the functions of two devices in one

Structurally, the device is a current transformer with a window, mounted on a busbar or cable like a standard measuring transformer. However, thanks to the built-in transducer, the device outputs a standardized DC signal in the 4-20 or 0-20 mA range, proportional to the measured current.

Rish CT Ducer devices are available in two sizes: one with a window for a busbar up to 30 mm or a cable up to 28 mm, and one with a window for a busbar up to 40 mm or a cable up to 30 mm. The smaller version can measure currents up to 300 A, while the larger one can measure up to 750 A. The device is powered by 220 V AC or 24 V DC

There are two versions of the device: one (AVG) is designed to measure the root mean square value of a slightly distorted sinusoidal current, and the other (TRMS) is designed to measure the true root mean square value of a current with a high content of harmonic distortion.
