Danisense fluxgate current sensor DQ600ID output PPM high-precision AC/DC probe (DC/AC)

Brand: Danisense, Origin: Denmark. Danisense current sensors are based on zero-flux gate sensor technology.

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

Fluxgate sensors measure weak magnetic fields by utilizing the nonlinear relationship between magnetic induction intensity and magnetic field intensity in a high-permeability magnetic core under alternating magnetic field saturation excitation. This physical phenomenon acts like a "gate" to the measured ambient magnetic field. Passing through this "gate," the corresponding magnetic flux is modulated, producing an induced electromotive force. This phenomenon is used to measure the magnetic field generated by current, thereby indirectly achieving current measurement. Fluxgate sensors are based on the nonlinear magnetization characteristics of core materials. Their sensitive element is a core made of high-permeability, easily saturable material, with two windings around the core: an excitation coil and a signal coil. Under the magnetization effect of an alternating excitation signal f1, the permeability of the core periodically alternates between saturation and non-saturation, inducing a signal in the surrounding coil that reacts to the external magnetic field. Danisense is a benchmark in the fluxgate sensor industry. The domestic Chinese high-tech company Hangzhi Technology uses multipoint zero-flux patented technology in its fluxgate products, making it an emerging global brand for high-precision current measurement.
