Linear Current Transformer Magnetic Cores

Basic Info

In modern measurement filed, linear transformer are widely used especially known as Hall sensor. The advantages of Hall sensor are good output signal and wide testing range etc. , while the drawbacks of Hall sensors are their high distortion degree of small signals and low testing frequency (usually less than 20khz).  Current transformer made of nanocrystalline closed-loop cores has a better performance under small current than Hall sensor. The usage frequency of linear transformer can be 100KHz which is 5 times that of Hall sensor. Linear transformer has a considerable advantage in precision measurement system.

We can make customized dimension and specification.
