Digital Start-up Channel
The DAK 250 digital start-up range channel forms
part of the proTK™ product line. It has been designed
for neutron fl ux monitoring in the pulse and inter-
mediate range in combination with pulse detectors,
e.g. BF3-counters and neutron ionization chambers.
Hardware and software of the DAK 250 are designed
and qualifi ed for applications at the level of the reac-
tor protection system.
APPLICATIONS
• Operational process monitoring
○ Safety related signal processing for neutron fl ux
monitoring in the pulse range (DAK 250-i) and
intermediate range (DAK 250-g)
RELATED PRODUCTS
• Neutron detectors: e.g. BF3-counters and
ionization chambers KNK/KNU 50
• Digital signal processing channels: e.g. for wide
range or power range monitoring
FEATURES
● Signal fi ltering with adaptive time constant

● Calculation of the fl ux change rate (reciprocal of the
reactor period)
●
Generation of analog and binary signals for the reactor
protection system
●
Linear and/or logarithmic analog outputs
● Remote test signal generators
●
Optional: calculation of the reactor reactivity
