Without the right equipment, precision power measurements can cause problems and delays. The LMG series precision power analysers from ZES ZIMMER offer an attractive solution. Current sensors are needed to measure high currents, which divide the current by a fixed ratio. To meet these needs ZES ZIMMER has also introduced the new DS200 and DS600 current sensors based on the zero flux technology.

Induced by the primary current, the magnetic flux is compensated by a secondary current - exactly proportional to the primary current. The DS200 converts currents up to 200 A with a ratio of 1:500; while the DS600 can be used up to 600 A and has a ratio of 1:1,500.

The intrinsic error of both current sensors is less than 0.5 ppm of full scale. The DS200 and DS600 current sensors work from DC up to frequencies of 100 kHz with an extremely flat frequency response.

Featuring a ruggedized aluminium housing, the new sensors guarantee optimal shielding against external noise. The operating temperature range is -40 °C to +85 °C and output connection is realized with LEMO, BNC, or DSUB connectors.

Bernd Neuner, Director of Global Sales at ZES ZIMMER, commented: “The need for high precision power measurement is continuously growing over the past years. We are therefore very happy, that we agreed on an exclusive distribution partnership with Danisense, allowing us to offer our customers a complete program of power measurement equipment.”
