Danisense fluxgate current sensor DM1200UB-1V voltage output PPM high-precision AC/DC probe (DC/AC)

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

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

A fluxgate sensor uses the nonlinear relationship between the magnetic induction of a high-permeability core and the magnetic field under alternating magnetic field saturation excitation to measure weak magnetic fields. This physical phenomenon acts like a "gate" for the measured environmental magnetic field, and the corresponding magnetic flux is modulated as it passes through this "gate," generating 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 elements are cores made of high-permeability, easily saturable materials, with two windings around the core: one is the excitation coil, and the other is the signal coil. Under the magnetization effect of an alternating excitation signal, the permeability characteristics of the core undergo periodic saturation and non-saturation changes, allowing the coil surrounding the core to sense signals responding to the external magnetic field. Danisense is the benchmark for fluxgate sensors in the industry. The domestic high-tech company Hangzhi Technology’s fluxgate products adopt multi-point zero-flux patented technology and are an emerging global brand for high-precision current measurement.
