IDEA #4X1TPL Low Noise Miniature Flux-Gate Magnetometer Lemi-019

LOW NOISE MINIATURE FLUX(cid:2)(cid:2)GATE MAGNETOMETER LEMI(cid:2)(cid:2)019 APPLIED RESEARCH • SENSORSDescription Miniature one(cid:2)component flux(cid:2)gate magnetometer LEMI(cid:2)019 is intended for the measurement of one component of the magnetic field vector in land conditions. The instrument has two outputs: low(cid:2)sensitivity unfiltered output for rough estima(cid:2) tion of magnetic field intensity and high(cid:2)sensitivity filtered out(cid:2) put for measuring of its weak fluctuation in the frequency band 0.02(cid:2) 5 Hz. Its peculiarities are low noise together with very low power consumption.

Other major advantage is that simultaneously lowest possible consumed power of the magnetometer is provided what makes these devices indispensable for autonomous sys(cid:2) tems. Serious advantage is also very competitive price – no more than 70% of regular market price for competitive devices Fig.1.
