Instruction of DC Current Sensor
MULTI DC Current Sensor is constituted of the combination of cut core and hole element as a magnetic sensor and it is possible to measure not only DC current but also AC current continuously.

[Measuring Prnciple of Hole Element Sensor]

The magnetic flux in proportion to the current flow(I1) to the conductor is converged in the core and cross over the hole element located in the gap of core.
Then, the voltage(VH) will be generated by the effect of hole element in proportion to the current flow(I1).
