Remarks
•

is positive when I
P
flows in the direction of the arrow.
•
The return busbar and primary conductor elbow must be located
at least at 2.5 x window length more far away from the transducer
case.
•
The temperature of the primary busbar can not exceed 90 °C.
•
Dynamic performances are the best with a primary busbar
completely filling the primary aperture.
•
This is a standard model. For different versions (supply voltages,
different outputs, bidirectional measurements...), please
contact us.
