This NK Technologies ATR series current transducer combines a solid-core current transformer and signal conditioner, and is suitable for use in industrial automation systems. The transducer provides true root-mean-square (RMS) measurement for sinusoidal alternating current waveforms, with an accuracy of 1.0% full scale (FS) and a response time of 600 ms (10-90% step change). A large aperture accommodates large diameter conductors or cables and user-selectable input current ranges reduce inventory needed. This current transducer is Underwriters Laboratories (UL) listed and Conformité Européenne (CE) certified for quality assurance. It is suitable for monitoring variable-frequency drive (VFD) and silicone control rectifier (SCR) alternating current (AC) loads and other “noisy” loads that produce distorted waveforms.

Current transducers are used to detect electrical current flowing in a wire or cable, and to generate an electrical signal proportional to the current for measurement or control. The transducer consists of an electrical winding, a magnetic core, and a signal conditioner. When current flows through a wire, the transducer winding generates a current, which produces a magnetic field in the core, which then creates a proportional current or voltage output signal. Current transducers are used in industrial automation systems for monitoring, alarming, and equipment control.
