Application information
Accuracy considerations
Several factors influence the output accuracy of Minisens as a current transducer:
The sensitivity of the Minisens is calibrated during production at 600 V/T ± 3%.
As already mentioned, the distance and shape of the primary conductor also influence the sensitivity.
No relative movement of the primary conductor to Minisens should be possible.
To avoid differences in a production, the position and shape of the primary conductor and circuit should always be identical.
The magnetic fields generated by neighbouring conductors, the earth’s magnetic field, magnets, etc. are also measured if they
have a component in the direction to which Minisens is sensitive (see figure 8).
As a general rule, the stronger the field generated by the primary current, the smaller the influence of stray fields and offset.
The primary conductor should therefore be designed to maximize the output voltage.
For more details on the accuracy calculation, please consult the “Minisens design guide”.
