Danisense fluxgate current sensor DR5000IM output PPM high-precision AC/DC probe (DC/AC)

Brand Danisense, made in Denmark. Danisense current sensors are based on zero-fluxgate sensor technology.

Ultra-stable, high-precision (ppm-level) fluxgate technology current sensors are used for non-intrusive, isolated DC and AC current measurements.

Fluxgate sensors measure weak magnetic fields by utilizing the nonlinear relationship between magnetic induction strength and magnetic field intensity of a high-permeability core under alternating magnetic field saturation excitation. This physical phenomenon acts like a “gate” for the measured environmental magnetic field; when passing through this “gate,” the corresponding magnetic flux is modulated and an induced electromotive force is generated. Using this phenomenon, the magnetic field generated by the current can be measured, thereby indirectly achieving current measurement. Fluxgate sensors are based on the nonlinear magnetization characteristics of core materials. The sensitive element is a high permeability, easily saturable core, around which two windings are placed: one is the excitation coil, and the other is the signal coil. Under the magnetization effect of an alternating excitation signal f1, the core's magnetic permeability undergoes periodic saturation and non-saturation changes, inducing signals in the coils surrounding the core that respond to external magnetic fields. Danisense is a benchmark in the industry for fluxgate sensors. The fluxgate products from China's high-tech company Hangzhi Technology use multi-point zero-flux patented technology and are an emerging high-precision current measurement brand globally.
