Description
Product parameters
Closed-loop fluxgate C-type current sensor
Features
Wide frequency range Low temperature drift
Good precision, good linearity
Fast response time No insertion loss
working principle
The magnetic field generated by the primary current IP is balanced with the magnetic field generated by the secondary coil current. HALL device and auxiliary circuit secondary magnetic compensation current, the current accuracy can reflect the primary current.
Closed-loop fluxgate IT-type current sensor
Features
Accuracy is very high
High temperature stability under high temperature
Low noise
Wide frequency atmosphere
Linearity <1ppm
No cross-distortion
working principle
The use of fluxgate technology Hall devices, the magnetic field generated by the primary current magnetic field generated by the secondary current compensation. The zero flux test detects a symmetrical detector consisting of two wound windings, which are connected to a square wave generator. Secondary compensation current can accurately reflect the primary current situation.
