LEM Announces ITZ Transducer Series
Milwaukee, WI - LEM® is pleased to announce the availability of its ITZ transducer series throughout the United States. ITZ transducers provide galvanically isolated measurement of AC, DC and pulsed currents.
The high-accuracy product range, which employs advanced closed-loop Fluxgate technology, comprises 14 models for nominal current measurements from 600 A to 24 kA with apertures from 25.4 mm up to 150.3 mm diameter. Overall accuracies at ambient temperature (25°C) are a few ppm (parts per million: 1 ppm = 0.0001%). The initial offset error is under 2 ppm; linearity in the range of 1 – 10 ppm; and extremely low thermal drift of 0.1 to 0.6 ppm/K (ppm per degree Kelvin).
The transducers are configured as measurement head plus rack-mounted electronics. They deliver measurements as an output current or voltage: in addition to these normal signal outputs, the transducers also provide outputs indicating the transducer state.
ITZ-series transducers have very low output noise and bandwidth varying from 2 to 500 kHz (+/- 3 dB) according to the model. The transducers tolerate substantial overload currents (to over 30 kA in the case of the highest-rated unit) for up to 100 msec. They are powered by standard AC mains supplies of 100-240VAC, 50/60 Hz and operate over a temperature range from 0 to +55°C for the measuring heads and from +10 to +40°C for the electronics rack.
The ITZ series is covered by LEM’s standard 5-year Limited Liability Warranty.
