This autonomous measuring station for our Gamma detector RS03/X permits measuring in an area where no infrastructure (telephone wiring and power supply) is available.
The unit is equipped with a 12 V solar station to supply the measuring instruments with power. The integrated accumulator is designed for a station operation time of about 30 days without power production and full accu capacity.
The data can be sent to a master station via GSM terminal modem. Consequently, the only requirement for the operation of this measuring station is the following:
The measuring station has to be in the receiving area of a GSM sending station. If this is not the case, the data transfer via radio or satellite can be used. Provided that one of the latter transfer systems is used, however, a change in the system set-up (power supply and data communication) is absolutely necessary.

If there is no data connection to the master station, the station can save the measuring data for one week. In this case, The WEBDL is in charge of saving the measuring data and of modem control. This Datalogger has been developed especially for use in this measuring station. Furthermore, this unit is fully compatible with our RSDL Datalogger, which implies that for both units only one control routine instrument is required in the master station.  

The entire casing of the measuring station is made of aluminium and has the protection class IP55. The casing has a double – wall design with very good isolation properties. For the installation, a strong concrete ground work should be available. For the mounting the sensor RS04/X, there are various options. The sensor is usually mounted on its own equipment, at a distance of several meters to the station to ensure that there is no influence on the direction dependence of the sensor. This kind of mounting, however, requires the installation of an earth wire to connect the sensors with the measuring station. A simpler installation option would comprise mounting the sensor directly on the measuring station with an expositor. (→ Direction dependence of the sensor changes)
