High-accuracy current transducers

October 2005 Sensors & Transducers

LEM's IT 400-S and the IT 700-S are specified respectively for 400 and 700 A rms nominal. As with other members of the family, they offer very high accuracy, based on resolution better than 0,05 ppm, linearity better than 3 ppm and an initial offset between 30 and 50 ppm. Thermal offset drift is low, at only 0,5 ppm/K.

Featuring galvanic isolation, the IT 400-S and IT 700-S can be used for current measurement of any kind of waveforms (including DC, AC, mixed and complex). They have been designed to operate from a bipolar ±15 V d.c. power supply and will accommodate round primary conductors of 26 and 30 mm diameter respectively.

In addition to their normal current output, the transducers offer an additional output indicating the transducer state (opened or closed contacts), and an external LED showing the normal operation.

With an operating temperature range of +10 to +50°C, the transducers will find applications in high-precision power supplies and high-performance gradient amplifiers for MRI (magnetic resonance imaging), as well as medical equipment such as medical X-ray imaging, but also calibration test benches in laboratories and test departments. They can also be used as interfaces for power analysers when high accuracy is required. The transducers are CE marked and supplied with a two-year warranty.
