1. PRESENTATION
The STTC probe is intended for the measurements of the ambient equivalent dose rate for gamma
radiations. It can be connected to any CSP survey meter via the appropriate connection cable. It allows
to widen the measure dynamics of the device and to run remote measurements up to 20 meters. It
comes under the shape of a compact and sturdy metal case which contains the Geiger-Müller detector,
the high voltage supply and the pulses shapers.
Due to its wide range of measure, it can be used in nuclear power plant to control very variable gamma
streams, but also in medicine or in emergency situation (measure after accident, fire brigades). It is also
possible to use this probe in measure of environment, combined with a remote communication device
CSP-COM, if the measure of the background is not exactly required.
STTC-W is the waterproof version of STTC. It includes a 20 meters cable on a reel and ballast. STTC-
W cable is mounted on probe body via a cable gland to ensure good waterproofness down to 40
meters.
The STTC probe can be connected to CSP survey meters and radiameters such as :
-Avior 4000 with a firmware version 1.08 or superior,
-Radiagem 4000 with a firmware version 4.22 or superior,
It can also be connected to a PC :
-equipped with CSPS Software version 2.0 or superior,
-equipped with a software using CSP-PL ™.
Note: the new versions of the firmware can be downloaded for free on the Canberra website:
www.canberra.com. See the user manual of the survey meter for the complete update procedure.
For connecting the probe to the CSP-COM, an aluminium adapter ring is provided.
