fluxgate current transducer
A fluxgate current transducer is a sophisticated measurement device that combines precision engineering with advanced magnetic sensing technology to accurately measure and monitor direct and alternating currents. This innovative device operates on the principle of magnetic field detection, utilizing a high-permeability core material that becomes periodically saturated by an excitation current. The transducer's primary component consists of two magnetic cores with excitation and measuring windings, enabling it to detect and measure current flow without direct electrical contact with the conductor. The device achieves exceptional accuracy levels, typically reaching 0.1% of the nominal current, making it ideal for applications requiring precise measurements. The fluxgate technology enables these transducers to measure currents ranging from a few milliamperes to thousands of amperes, while maintaining excellent linearity and temperature stability. The transducer's non-intrusive measurement capability, combined with its robust galvanic isolation properties, ensures safe and reliable current monitoring in various industrial and scientific applications. Its ability to provide real-time measurements with minimal phase shift and exceptional dynamic response makes it particularly valuable in power quality monitoring, precision control systems, and high-performance industrial automation.
