Introduction
The weak magnetic field measurement system is mainly composed of data acquisition box (up to 5 CAN interface data acquisition modules can be integrated inside), magnetic sensor, host computer software, etc. The whole system adopts 24V power supply and communicates with PC based on CAN bus and USB, which can realize the synchronous acquisition of magnetic field data in the area to be measured.
Features
Reliable communication and strong anti-interference ability
Application
A multi node weak magnetic field test system can be formed
