12V 400A Medical Magnetic Field Hall Effect Current Sensor

Product Description

Introduction:

Close loop hall current sensors is a new generation of current sensor which applies hall effect principle, can measure direct current, alternating current, pulse and current of various irregular wave forms in electrical isolation conditions. Higher accuracy and linearity, short responding time and wide frequency band make it widely used in current monitoring devices, high current protection and other fields. 

The product has many other advantages:

firm structure, low power consumption, small size, light
weight, long lifetime, easy installation, vibration resistance, water vapor proof and dust proof, which assure convenient and reliable usage. And users can define the rated primary current and secondary rated output based on actual demand.

 

Working Principle:
The magnetic field produced by primary current Ip is balanced with
the magnetic field produced by secondary coil current. The hall
unit and auxiliary circuit produce secondary magnetic compensation current that can accurately response the primary current.

NOTE:
We can design and produce open loop hall sensors:
Open loop hall current sensors use the open loop hall direct testing principle to test direct current, alternating current and pulse current, the primary current is electrical isolation with secondary output signal. The output value can be customized. This produce has core through structure, no insertion loss, various case styles. For split core structure, there is no need to cut off the primary bus for installation.
