• Application:

The long-period magnetotelluric station LEMI-420E is developed for measurements of the telluric field - signals with the periods 20... 100.000 seconds register with very high sensitivity and low drift. For realization of such design the main attention was paid to thermal and temporary stability, a big entrance impedance and low drift of electric channels. For a transmission of signals of the superlong period the technology of high-frequency filters of entrance steps was used. The block of lightning protection provides both protection against close lightning categories, and simple connection of electric lines in field conditions. In the device there are four electric channels for measurements of in addition vertical component of the telluric field or components along some local geological structure. Specially developed LEMI-701 electrodes with very low noise level are recommended (for a photo, on the right), but also any other types of electrodes can be used.
