  • Anti-jamming technology for analog sensors(4)

    4.Low frequency magnetic shielding   If the interference is a low-frequency magnetic field, the eddy current phenomenon is not obvious at this time, and the anti-interference effect is not good only by the above method. Therefore, a high-permeability material must be used as a shielding layer in ...

  • Anti-jamming technology for analog sensors(2)

    2.Static shielding   According to the principle of electromagnetics, there are no electric field lines inside a closed hollow conductor placed in an electrostatic field, and its internal points are equipotential. Using this principle, a copper or aluminum metal with good conductivity is used to m...

  • Selection principles of sensors (4)

    Selection principles of sensors (4) 4.Linear range   The linear range of the sensor is the range where the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the sensor, the larger its range is, and it can guarantee a...
