Typical Applications of Hangzhi High Precision Current Transducer

AIT high precision current sensor & MRI

In the MRI system, the gradient amplifier unit refers to all circuit units related to the gradient magnetic field.

Its function is that the system provides linearity that meets the requirements and can quickly switch the gradient field to determine the slice position and imaging slice degree; the linearity of the gradient coil is an index to measure the stability of the gradient field. The better the linearity, the more accurate the gradient field, and the better the image quality. The current linearity inside the gradient coil highly depends on the current controller and current measurement which is done by high precision current transducer.

Hangzhi AIT series high precision current sensor have been integrated into various electrical testing benches for AC or DC current measurement purpose, such as convertor/invertor and transformer testing benches.

Hangzhi AIT 0-10V output high precision current transducer (AIT60/200/300/600/1000) are compatible with most power analyzers, such as:

YOKOGAWA: WT3000 & WT1800 series power analyzer;
