Danisense fluxgate current sensor DM1200ID 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.

Fluxgate sensors utilize the nonlinear relationship between magnetic induction and magnetic field strength in a high-permeability core under alternating magnetic field saturation excitation to measure weak magnetic fields. This physical phenomenon acts like a 'gate' for the measured environmental magnetic field. As the 'gate' is passed, 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. The sensitive element is a core made of high-permeability, easily saturable material, with two windings around the core: one is an excitation coil and the other is a signal coil. Under the magnetizing effect of the alternating excitation signal fl, the core's magnetic conductivity 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. In China, high-tech enterprise Hangzhi Technology's fluxgate products adopt multi-point zero-flux patented technology and are a rising brand in global high-precision current measurement.
