The PM 99/1 is a classical proton magnetometer controlled by an internal micro processor.
The frequency adjustment of the sensor and amplifiers will be done in 256 steps automatically
in dependency of the external field magnitude.
Also the polarisation current depends on the
external field. The design of the sensor coil provide a optimal protection against
electromagnetic interferences. Single measurements as well as short time series are
supported by the data acquisition system.
Therefor the PM 99/1 can be applied in
geomagnetic observatories, for repeat station measurements and to investigate local
geomagnetic anomalies.
In connection with a PC are also possible registrations
of the variation of the geomagnetic total force during longer periods.
Together with an adjustable current source , an also by MAGSON GMBH developed
coil system and a suitable mechanical basis the PM99/1 can be used furthermore for
geomagnetic vector measurements.
