Περιγραφή
Hall sensor is suitable for isolation and conversion of complex signals such as AC, DC, and pulse. Through the principle of the Hall effect, the converted signal can be directly collected and accepted by various acquisition devices such as AD, DSP, PLC, and secondary instruments.
Small size, long life, easy installation, fast response time, wide current measurement range, high precision, strong overload capacity, good linearity, and strong anti-interference ability.
