Release Time：2020-10-14
AC High Current Sensor-Hubei Huaguan
AC high current sensor is a new generation of current sensor based on the direct measurement principle of Hall effect. It can measure AC, pulse and various irregular waveform current sensors under the condition of electrical isolation. The sensor adopts autocratic aluminum alloy shell, epoxy resin pouring, unique magnetic circuit structure, with residual magnetism and small, magnetic circuit will not saturate overload capacity infinite, strong impact current resistance, fast response speed, stable and true zero point, stable work, high reliability, high precision, low power consumption characteristics, can accurately detect the measured current. It is an ideal product for energy saving and optimization control in smelting industry. Bring high economic effect to the user. Can be widely used in electric arc furnace, refining furnace, ferroalloy furnace smelting production transformer secondary side strong current control, protection, measurement.

The two-stage automatic temperature compensation technology is adopted to solve the problem of temperature change of precision instruments and electronic devices and ensure the stability of long-term operation.
● The sensor output signal is isolated from the measured high current and high voltage to ensure the safe operation of the current stabilization system, control system, protection system and display.
The unique magnetic core structure design solves the interference of stray magnetic field and ensures the accuracy of the sensor.
All core components are military grade devices, improve product reliability.
● The output signals are isolated from each other and do not interfere with each other, which makes the matching of the high-current DC control system more convenient.
The two-part docking mode of the opening type is very convenient for installation, use and maintenance.
● Full epoxy resin encapsulation, to avoid the corrosion of the circuit in the harsh environment, improve the service life and stability of the sensor.
