Zero flux current sensor offers high precision benefits

August 06, 2013 // By Paul Buckley
To allow the measurement of high currents, current sensors are needed, which divide the current by a fixed ratio. For these applications ZES ZIMMER is offering Danisense's DS200 and DS600 current sensors based on the zero flux technology.

The magnetic flux, induced by the primary current, is compensated by a secondary current, which is exactly proportional to the primary current.

The DS200 converts currents up to 200 A with a ratio of 1:500, the DS600 can be used up to 600 A and has a ratio of 1:1,500. The intrinsic error of both types is less than 0.5 ppm of full scale. The current sensors work from DC up to frequencies of 100 kHz with a flat frequency response. The ruggedized aluminium housing guarantees optimal shielding against external noise. The operating temperature range is -40 °C to +85 °C. The output connection is realized with  LEMO, BNC, or DSUB connectors.

ZES ZIMMER has an exclusive distribution agreement with Danisense for the German market.
