Current measurement transducer
Dewesoft DC-CT-1000I current transducer is designed for precise current measurement applications. It is based on current-controlled variable reluctance (CCVR) and offers all the benefits of a zero-flux current transducer but with lower power consumption and in a smaller form factor.
The DC-CT transducer can be seen as an AC current transformer, where primary and secondary windings are coupled by a common high permeability core. Just as with other closed-loop techniques our technology continuously measures residual magnetic flux in the core resulting from the difference between the primary and secondary currents. The detected difference drives the feedback control mechanism that adjusts the current in the compensation winding to achieve the optimal zero-flux balance in the core.
DC-CT technology with the Platiše Flux Sensor (PFS) represents the latest current sensing technology suitable for accurate current measurements. The device offers:
A wide measurement range.
Very high accuracy.
Very low-temperature drift.
Low power consumption compared to other zero-flux type current transducers. Lower power consumption also enables a more compact form factor.
