LEMI-024

Product type:
Fluxgate Magnetometer

Product description:

LEMI-024 is an analog three-component fluxgate magnetometer with two sets of outputs. The low-sensitivity unfiltered output is capable of monitoring the magnetic field intensity to the full range of the earth’s magnetic field in the frequency range from DC to 500 Hz. The additional high-sensitivity filtered output is used to measure weak magnetic fluctuations in the frequency band from 0.003 Hz to 10 Hz. The LEMI-024 features low noise levels, an extended temperature range of operations, and low power consumption.

LEMI-024 can be used in geomagnetic or magnetotelluric applications as well as in monitoring and field compensation applications. Due to its dual output design, the full-scale earth magnetic field and weak field variations can be measured. Both outputs can be used simultaneously in high accuracy compensation circuits.

Product Highlights:

High sensitivity filtered output
Noise ≤ 6pT/√Hz @ 1 Hz
