CLOSED LOOP SENSORS

Closed loop current sensors measure

AC, DC and impulse currents over 0-25,

0-50, 0-100, 0-600 and 0-1200 Amp rang-

es. The CSN Series is based on the princi-

ples of the Hall effect and the null balance

or zero magnetic flux method (feedback

system). The magnetic flux in the sensor

core is constantly controlled at zero. The

amount of current required to balance

zero flux is the measure of the primary

current flowing through the conductor,

multiplied by the ratio of the primary to

secondary windings. This closed loop

current is the output from the device and

presents an image of the primary current

reduced by the number of secondary

turns at any time. This current can be

expressed as a voltage by passing it

through a resistor.
