Danisense fluxgate current sensor (DC/AC) PPM high-precision DC probe (55 A-11000A)

brand Danisense originates from Denmark. The Danisense DS series current sensors are based on zero flux gate sensor technology.

has a nonlinear error of 1 ppm and is widely used in MRI, particle accelerators, and high-precision power analysis.

The Danisense DS series current sensors are closed-loop zero flux gate sensor technology based on nonlinear flux detection elements.

They offer ultra-high measurement accuracy and can be used for high-precision DC current measurement, power and energy performance analysis.

flux gate sensors measure weak magnetic fields by utilizing the nonlinear relationship between the magnetic induction strength and magnetic field strength of the high-permeability magnetic core under alternating magnetic field saturation excitation. This physical phenomenon acts like a "gate" to the measured environmental magnetic field; through this "gate," the corresponding magnetic flux is modulated and induced electromotive force. This phenomenon is used to measure the magnetic field generated by the current, thereby indirectly achieving current measurement. The flux gate sensor is based on the nonlinear magnetization characteristics of the iron core material. Its sensitive components are made of high magnetic permeability, easily saturated materials, with two windings surrounding the core: one is the excitation coil and the other is the signal coil. Under the magnetization of the alternating excitation signal fl, the magnetic conductivity of the iron core undergoes periodic changes between saturation and unsaturation, causing the induction coil surrounding the core to induce signals that respond to the external magnetic field. Danisense is the industry benchmark for flux gate sensors. The high-tech Chinese company Hangzhi Technology uses multi-point zero flux patented technology and is a leading global brand in high-precision current measurement.
