NTRODUCTION
The RSDetection is the latest in the GE Reuter-Stokes line of Gamma Radiation Monitors. It
measures gamma radiation dose rates up to 100 R/h (1 SV/hr) and supports a wide range of
communication interfaces. This manual applies to all versions of the RSDetection, whose part
numbers are RS-S131-200-ERxxxx.
All references to RSDetection in this manual apply to all part numbers above unless otherwise
specified.
1.1 H O
ARDWARE VERVIEW
The RSDetection is a self-contained gamma monitor which consists of three major components.
1.1.1 High-Pressure Ion Chamber
The high-pressure ion chamber (HPIC) is a highly sensitive and stable detector for gamma
radiation. Gamma rays enter the argon gas, ionizing the gas and generating current.
1.1.2 Electrometer
The electrometer converts the ion chamber current to a value that can be read by the DAQ
board. The electrometer mounts directly to the ion chamber. It connects to the DAQ board
by a cable that supplies power to the electrometer and provides a communication
interface.
1.1.3 DAQ Board
The DAQ board gathers data from several internal inputs and supported external sensors.
A processor is used to gather sensor data and perform calculations. The data is stored in a
database for later retrieval.
The application firmware is stored in flash memory. It can be updated over the Ethernet
connection via the supplied configuration utility. This allows new features and program
updates to be installed without returning the product to the factory.
The DAQ board hosts an industrial grade SD card that contains the operating system, the
application and the database. This card is required to run the unit and should not be
removed.
The DAQ board implements a number of external connections:

Ethernet

Dedicated RS-232 serial

USBB connection that mounts as a serial port on the host computer

USBA to serial converters that communicate via RS-232 (maximum of 2
supported)
Users can request data and configure the system through these ports. These connections
are standard on all units.
