FT-SCA high-precision current sensor is a current sensor that can measure DC, AC, pulse and various irregular waveforms under the condition that the primary side and secondary side are completely isolated. FT-SCA series adopts multi-point zero flux technology to control the excitation flux, DC flux and AC flux in a zero flux closed loop, and realizes the detection of high-frequency ripple by constructing a high-frequency ripple induction channel, so that the sensor has relatively high gain and measurement accuracy in the full bandwidth range.
The FT-SCA series is mainly used in the fields of metrological verification and calibration that require high accuracy, as well as power quality analysis, power analyzer, medical treatment, aerospace, rail transit and other fields that require high sensitivity, stability and reliability.
Multipoint zero magnetic flux technology
The magnetic core reaches the magnetic balance state by excitation. When the measuring current flows through the wire, breaking the magnetic balance, the flux gate will generate the excitation current, and the signal will drive the compensation coil after amplification, so that the magnetic flux in the magnetic core and the magnetic flux generated by the measuring current will cancel each other and remain in the "zero" state, that is, the so-called "zero flux" state.
