High Precision Transducers

The LEM high precision product range covers transducers for nominal current measurements from 12.5 A to 25 kA while providing overall accuracies at ambient temperatures (25°C) of only a few PPM. Thermal offset drifts are extremely low from only 0.1 to 6.7PPMK. Models from 12.5 A to 60 A nominal can be used for PCB mounting, and models from 60 A to 25 kA are for panel or rack mounting with either on-board or separate electronics. In addition the Flux-gate technologies used to provide Galvanic isolation for current measurements of all types of waveforms including AC, DC, mixed signal or complex waveform.
To obtain these exceptional performances, closed loop fluxgate technology has been used, coupled with a top-class current transformer. This combination enables precision current transducers having high accuracy and dynamic performance with a wide measuring range.
