Setting the benchmark for accurate current measurement
This catalog summarizes the most common LEM To achieve this challenging target of accuracy and
product offerings for highly-accurate electrical current performance, LEM’s IT current transducers do not use
measurements for industrial and laboratory applications. the Hall Effect but are based upon Flux-gate technology,
It is LEM’s business to provide you with both standard an established and proven technology we have used for
and customized products and solutions optimized to your many years and is already the heart of several current and
specific needs and requirements. voltage transducer families. Today, LEM uses different
Certain power-electronics applications require such high versions of Flux-gate technologies, each providing
performance in accuracy, drift and/or response time that different levels of performance and cost to match the
