Audited Supplier Hall current sensors are mainly used to isolate and convert AC, DC, pulse, and other complex signals. After signals are converted according to the Hall Effect Theory, they can be directly acquired by AD, DSP, PLC, secondary instruments, and other devices. Hall current sensors are widely applicable for acquisition and feedback control of current signals in the current monitoring, battery application, inverter, solar power management, direct current cabinet, DC motor drive, electroplating, welding, frequency converter, UPS servo control systems. They feature quick response, a wide range of measurements, high precision, strong overload capacity, good linearity, and excellent anti-interference performance.
HALL open-loop current sensor
★ Technical features:
(1) Small volume
(2) Wide measuring range
(3) Light weight
(4) Low power consumption
(5) No insertion loss
★ Working principle:
After the magnetic field generated by the primary current IP is concentrated through the magnetic core, the HALL induction chip is used to induce the size and direction of the primary current IP at the air gap of the magnetic core. The output voltage of the HALL induction chip passes through the signal processing circuit, so that the output of the sensor can accurately reflect the magnitude of the measured current. In order to improve the performance of the HALL open-loop sensor, silicon steel or permalloy is usually used as the material of the magnetic core. When the operating frequency of the measured current is greater than 10kHz for a long time, the sensor may be damaged by the heating of the magnetic core.
