Company Information
IN Series
Ultra-accurate currents sensors ranging from 100 to 2,000 A.
Fluxgate Technology reinvented
IN series, for all High-precision applications
The IN family is LEM’s most advanced high precision group of transducers. With its patented and ground-breaking digital integration technology, the IN represents a significant evolution to LEM’s older High Precision transducers. The IN transducers offer best-in-class performance, with the highest accuracy in the market, and low noise over wide operating temperature range. Fluxgate technology reinvented (LEM patent).

FLUXGATE TECHNOLOGY REINVENTED
The use of fluxgate technology in transducers for precise current measurement is well-known. However, it has some limitations linked to the ripple derived from the excitation voltage. LEM’s innovation takes fluxgate current transducers to previously unachieved performance levels through digital technology.
This digital technology brings a number of benefits.
- Immunity to temperature effects, interference and supply voltage variation
- A major reduction of the ripple from the fluxgate driving signal
