Observatory
Applications
The EUROMAG instrument is the total field magnetometer / gradiometer of
choice for customers who require:
• Minimal drift
• Continuous, stable measurement
• High sensitivity
• Reliability
Users may also be interested in the GEM's new Suspended dIdD magnetometer
which can be accessed via the
Vector Magnetometers product page.
EUROMAG Benefits
The GSM-90 is a high sensitivity Overhauser effect magnetometer. Main
benefits include:
The instrument is a secondary standard for measurement of the Earth’s
magnetic field. The system has 0.01nT resolution, and 0.2nT
absolute accuracy over its full temperature range.
The GSM-90 is available in two versions – a slow reading version and
a fast reading version for flexibility. Each consists of one
(170x70mm) cylindrical sensor, and a sturdy aluminum package
(220x245x70mm) which contains all the unit’s electronics.
The instrument is microprocessor based for full remote control
capability and time-savings. The results of measurement are
available in serial form (RS-232-C interface) for collection by data
acquisition systems, terminals or computers. The same RS-232 link
provides the means of control to the instrument.
Understanding the
GSM-90 Measuring Sequence
The GSM-90 is a compact version of the GSM-19 Overhauser magnetometer
that:
• Cycles from
0.2 seconds to 1 hour (depending on the version - Fast or Slow)
• Includes a standard “Observatory” mode.
Observatory mode measures over 5 second intervals and outputs an average
value every minute. The time of the averaged reading is considered to be
the time of the middle reading.
• Can optionally be equipped with an AC
deflect pulse (long or short) in order to minimize interference with
other observatory instruments.
The instrument does not have a keyboard
and display; therefore, all control of the instrument is
through a computer or terminal.
GEMLinkW (PC Software) supplied with GSM-90 can be used for this purpose. Any other communication software commercially available (like Xtalk,
Flashlink Mirror, Hyperlink etc.) capable of sending and receiving RS232
can also be used. Communication is very simple and
requires sending only few bytes to the magnetometer.
