DISCOVERY 5302 IC Series

ENVIRONMENTAL GAMMA RADIATION MONITORING UNIT

The DISCOVERY 5302 IC monitoring unit is a modular system for gamma dose measurements, assembled in a highly protected insulated PVC housing.

The detector is a pressurized ion chamber (IC); alternatively, the version IC-T is available, which allows to extend the lower energy range down to 40 keV, if needed.

DISCOVERY 5302 IC comes in two standard versions: with an electrometer for pulsed field measurements (7 decades) or with an electrometer for environmental measurements (9 decades). The Acquisition and control unit processes and locally displays the data coming from the detection unit (i.e. the dose rate or the integrated dose value) and eventually indicates the alarm or malfunctioning conditions, through acoustic and luminous signals. The measurements are automatically saved in a non-volatile circular memory buffer.

DISCOVERY 5302 IC can be used outdoor, and it can be easily mounted on a telescopic tripod with adjustable legs, to be positioned where needed. On the front side of the housing are installed the water proof LCD display and the function buttons panel; the connections to the power set, as well as the Ethernet or RS485 connection to the remote station and to other eventual external devices (i.e. alarm repetition), are on the back side of the housing.

 
The processed measurements can be shown by the local display or the remote Host PC, which can be connected to the unit through a cable or wireless communication. The alarm thresholds and the operative parameters are saved in the non-volatile memory, and can be set by the operator either locally or through the remote management software (option).

 

The low voltage power supply can be provided by the built-in rechargeable batteries, which have an autonomy of 4 hours, in case of remote measurements or should a power outage occur.

The XBee Pro wireless communication complies to standard 802.15.4/Multipoint Network Topologies, and allows communication up to 1 km in open space or 100 m indoor. A simple XBee compatible USB adaptor is needed on the PC. As an alternative to the XBee interface, a GSM modem can be used. In the monitoring unit can also be installed a satellite GPS locator, which associates the acquired measurements with the position. The Ethernet interface is also available in the IEEE 802.11b version (Wireless LAN).
