Current sensors monitor ac or dc current. Included are adjustable linear, null balance, digital, and linear current

sensors.

Digital current sensors can sound an alarm, start a motor, open a valve or shut down a pump. The linear signal

duplicates the waveform of the current being sensed, and can be used as a feedback element to control a motor or

regulate the amount of work being done by a machine.

CSN Series

Closed Loop Current Sensors

Closed loop current sensors measure ac, dc and impulse currents over 0-25,

0-50, 0-100, 0-600 and 0-1200 Amp ranges. The CSN series is based on the

Hall effect principle 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.

The CSN Series has a high overload capacity, a high level of electrical

insulation between primary and secondary circuits and a rapid response rate.

Lightweight and compact, and with no restriction on input current waveform,

the sensors are ideal for variable speed drives, power supplies, feedback

control systems, robotics/welding equipment and general overcurrent

protection.
