14.0 Portal Controller
14.1 Technical data
The STS Portal simulator is a simulated radiation survey meter designed to aid the
tuition of workers in the nuclear industry in safe practices and in understanding the
nature and mechanics of ionising radiation.
The instrument operates using an STS radio frequency detection head which detects
the presence of a simulated radiation field, generated by the Safe-PocketSource,
with the resultant reading activating a LED beacon and sounder.
Supplied by 12V power pack from
mains 240V supply via input jack.
LED Amber alarm beacon directly
wired into controller
Direct wiring from controller to portal
detector.
Operating & Storage Temperature
The STS Portal Controller is not designed to be intrinsically safe and therefore should
not be used in hazardous environments. The units are not waterproof and contain
delicate and sensitive electronics which may be caused to fail if exposed to moisture.
Units should be stored in a clean and dry environment, batteries should be removed
if storing for more than 4 weeks.
Instrument response will be affected by environmental conditions such as the
presence of large reflective surfaces, substantial metal structures and variable wall
thicknesses.
