Ultra-accurate and low noise level current sensors ranging from 200 to 2,000 A.
The IN family is LEM’s most advanced high precision group of current sensors. They can be used for the electronic measurement of current: DC, AC, pulsed..., with galvanic separation between the primary and the secondary circuit.
With its patented and ground-breaking digital integration technology, the IN electronic parts represents a significant evolution to LEM’s older High Precision sensors. The IN transducers offer best-in-class performance, with the highest accuracy in the market, and low noise over wide operating temperature range. The IN sensors can be mounted on panels either flat or vertically.
The IN current sensors are relying on a reinvented closed loop Fluxgate technology (LEM patent), enabling their high precision, among other benefits. They find applications not only in the industry but also in settings such as laboratories and medical environments.
IN sensors are commonly utilized in industrial, laboratory, and medical applications. It is typical to find IN high precision sensors in the following applications:

IN 2000-S | Datasheet 3D | 2000 A | Current | 15 to 15 | -40 to 85 °C |
IN 2000-SB | Datasheet | 2000 A | Voltage | 15 to 15 | -10 to 70 °C |
IN 2000-SB/SP1 | Datasheet | 2000 A | Voltage | 15 to 15 | -40 to 85 °C |
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.
