Description
LEMI-417M digital
seven-component magnetotelluric station (MTS) (three magnetic + four
electric channels) is intended for the measurement of natural magnetic and
electric field components and their variations in laboratory and field
conditions. The magnetometer is produced on the base of flux-gate sensor,
all three components of which are implemented in the same thermostable
housing. The electrometer has four channels with high input resistance and
offset compensation, which can operate with any type of measuring
electrodes. The electronic unit allows acquisition, processing and storage
of data about magnetic and electric fields variations in internal memory and
their transmission to the computer via RS-232 (or RS - 422) interface.
Built-in GPS receiver provides satellite synchronization of the internal
clock and the coordinates of the MTS location. MTS operation algorithm
allows organizing both autonomous and synchronous operation of a set of the
MTS installed at the studied area.
Several sensor options, e.g., tilt compensated sensor, for observatory and
laboratory use with leveling facility, hermetically sealed sensor etc. may
be selected. We are flexible to adopt every parameter to your needs.
Innovative Aspect
and Main Advantages
LEMI-417M major
advantages are very low temporal drift and high accuracy of measurements,
what makes it especially efficient for deep sounding application. LEMI-417M
is high
sensitive device, which has unique low power consumption
– 1W at the
maintenance of main technical characteristics at the level of the best word
standards.
The station has
waterproof housing and can autonomously operate during 6 months and longer
in wide temperature range.
Areas of Application
LEMI-417M
is used for deep sounding of the Earth’s crust and the determination of
vertical resistivity profile parameters down to
400 km with
the purpose of mineral prospecting and search of earthquake precursors.
