DIGITAL SIGNAL PROCESSING CHANNELS TK 250
Mirion Technologies (MGPI H&B) GmbH offers type tested
neutron fl ux monitoring channels system TK 250 for signal
processing of the output signals of KNK/KNU 50 neutron
ionization chambers, and for all other types of neutron
detectors:
●
DAK 250-g: digital start-up channel
for the pulse range and for the intermediate range
●
DGK 250: digital power range channel
These signal processing channels are characterized by
effi cient functions, useful procedures for periodic testing,
a comfortable operator’s interface structure, and a stable
operational behaviour. They are designed and qualifi ed
for applications within the reactor protection system.
