The Ludlum
Model 2100 automated radiation sample counting system processes sample steel
slugs to determine whether any radioactive impurities exist. The gamma
radiation counting system is a table-mounted, fully integrated design that
includes a gamma detector, sample conveyor, and controller to facilitate
automated processing.
Once the sample has been positioned on the conveyor, an infrared sensor
automatically initiates conveyance of the sample into the lead shielded detector
where it is counted for a predetermined time. Once the count is completed, the
conveyor again advances until the sample drops into a discard container. The
counting electronics incorporates two channels to distinguish between low and
high energy gamma isotopes. All parameters, such as alarm point and count
time are user-adjustable from the front panel LCD touch screen via a simple menu
selection.
Measurement results for each sample are displayed on the backlit LCD. An
Ethernet port reports all results and system status in real time for remote data
logging and alarm annunciation. Visual and audible alarms are annunciated via
the system’s LCD and rear panel mounted buzzer respectively. A built-in relay
provides a method for driving an external horn/strobe (available as an option).
Ludlum also offers an optional Ethernet-based Model 272E remote display for
conveniently displaying of one or more sample counters.
One rear panel mounted USB port enables connection to either a keyboard or
barcode reader device for the purpose of entering sample ID’s.
