INDUCTION MAGNETOMETER LEMI-153


The induction coil magnetometer LEMI-153 is intended to be used for the study of 3 components of magnetic field fluctuations in land conditions in frequency range 100 Hz – 1000 Hz with central frequency ~ 433 Hz. It can be used autonomously with any analog registration unit.
Very low power consumption allows for long period measurements at remote sites. A rugged and waterproof housing combined with a waterproof output connector prolong the sensor’s active lifetime and ensure overall reliability.
The circuit design and magnetometer construction use several industry specific procedures as well as new technological processes that provide the best possible combination of metrological and operational parameters. Each individual LEMI-153 magnetometer is experimentally tested and certified.
