Application description:
LEMI-022 vector magnetometer for the precise measurement of Earth’s magnetic field and its variations at laboratory and land conditions as well as in geomagnetic observatory is produced on the base of flux-gate sensor, all three components of which are implemented in the same body. It consists of two units – sensor unit with adjustable support and electronic unit both connected by long cable. The electronic unit allows automated operation – acquisition, processing and storage of data about magnetic field and its variations and their transmission at request to the external user via RS232 interface. Built-in GPS receiver can be added which provides satellite synchronization of the internal clock and the coordinates of magnetometer location.. The internal non-volatile memory for data recording can be optionally installed too. Small power consumption permits to use the magnetometer for long-term autonomous measurements in land conditions.

Highlights:
Low power consumption
