AC current measuring transducers and AC/DC current measuring transducers

Here you will find the appropriate measuring transducer for measuring direct, alternating and distorted currents. The range includes various options across a broad measurement range: from very low currents starting at 0 mA to 100 mA, up to higher currents of 600 A. For quickly adding additional measurement points to existing installations, versions with a removable Rogowski sensor are available.
