Digital Wide Range Channel
The DWK 250 digital wide range channel forms part
of the proTK™ product line. It has been designed for
neutron fl ux monitoring combining pulse and inter-
mediate range in combination with only one detector,
e.g. in-core or ex-core wide range fi ssion chamber.
Hardware and software of the DWK 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 combining pulse range and intermediate
range
RELATED PRODUCTS
• Neutron detectors: e.g. wide range fi ssion
chambers
• Digital signal processing channels: e.g. for pulse
range or power range monitoring
FEATURES
● 10 to 12 decades of measurement range with one
detector only
● Calibration into neutron fl ux units (nv, P/Pn)
●
Filtering of the signal with an adaptive time constant
●
Calculation of the relative fl ux change rate (reciprocal of
the reactor period) for the whole wide range
●
Generation of analog and binary signals for the reactor
protection system
●
Remote test signal generators, even in the preamplifi er
● The correct function of all signal pathes can be tested
before start-up
