INDUCTION MAGNETOMETER FOR
GEOPHYSICAL
APPLICATIONS LEMI-142
Main features
|
High sensitivity |
|
Low noise, near the
theoretically lowest possible level |
|
Frequency band 1 ... 500 kHz |
|
Low
power consumption |
|
|

|
|
|
New calculation methodology using minimal
mass criterion allowed minimizing the weight, conserving low noise level
in wide frequency band. The magnetic feedback design is utilised what
provides a stable response of full frequency band. Low noise
preamplifier is placed inside the sensor body. |
