Highly precise current measurement

In many industrial applications, highly-precise current measurement is key to equipment performance. Minor inaccuracies can cause major problems. Whether for medical equipment or other industrial applications, LEM transducers set the standard for current measurement accuracy and are the most precise industrial products on the market today.


Main applications for High Precision

LEM Wafer

Medical equipment accuracy

The quality of the image provided by MRI scanners is directly linked to current measurement accuracy and, therefore, to the current sensor performance. If the transducer is not precise enough this will lead to a blurred and illegible image. LEM high-precision sensors are used for these MRI scanners and other medical equipment requiring faultless power control.

High-precision equipment validation

LEM has been the leader for years in producing ultra-precise and cost-competitive current sensors for both traditional and high-performance industrial equipment testing. They provide levels of stability and precision, in the parts per million (PPMs) of the nominal magnitude, which makes them references in calibration test benches and recognized laboratories.

Typical applications for High Precision

  • Test & Measurement
  • Medical equipment (scanners, MRI, etc.)
  • Precision motor controllers
  • Metering
  • Power Analysers
