The model LEMI-011 is a complete 3 axes flux-gate magnetometer manufactured in two versions: monoblock (“tube” and “box” shape, sensor included) and as a p.c. board and sensor with cable up to 3 m long. Its peculiarity is super-low power consumption – min about 5 mW. The analog output voltages along each component (relative to “REF” output) are proportional to the measured magnetic field. Also the temperature channel is available, what allows to use this data for both outside temperature measurements and magnetometer thermal drift correction. Connection to the registration system is realized through standard RC7 connector for the monoblock construction and through 7 long flying leads for p. c. board one.
