High linear transformer

Product

Advantage

Defect

Hall sensor

1、Good linear output

2、Current range is large

3、Can measure DC current

1、When the current is small, the error is large

2、Need additional power supply

3、Poor temperature stability -40-85℃

4、Narrow frequency range （0-20KHz）

High linear CT

1、Small current to high current rang e can maintain high accuracy

2、Application frequency up to 100K

Hz, is 5 times the Hall sensor

3、Good temperature stability -40-8

5℃

Cann’t be used to measure DC current (But by changing the production process, t he back end of the circuit using magnetic modulation / fluxgate technology, can meas ure DC current, precision is better than 0.0 1% )
