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.
