Magnetic current sensors are devices that detects electric alternating current (AC) in a wire, and generates a analog voltage signal proportional to it. It can be then utilized to display the measured current, phase, and shape or the voltage signal output can be stored for further analysis in a data acquisition system or the signal can be utilized for control purpose to manage the current flow in a system.
The current sense range can be set from a few mAmps to thousands of Amperes. The magnetic types allow very high insulation voltages between the line measured and the sensing circuits.
- Very high absolute amplitude and phase accuracy from a few Hz to over 100MHz
- Low signal output noise
- High operating temperature range
- Reduced mechanical dimensions
- Current ranges from ±1 mArms/±100,000A
- Voltage output signal from calibrated winding ratios from 10 to 10,000
- Allows amplitude, phase and shape measurements
