DWK 260™

Digital Wide Range Channel

Neutron flux monitoring over the full range with one wide range fission chamber.

Tag Features

  • Modular design, highly customizable
  • 10+ decades of neutron flux range coverage with one fission chamber
  • Calibration of signal into units of neutron flux (nv) or reactor power (%FP, W,...)
  • Seamless calculation of the relative flux change rate (reciprocal of the reactor period) over the full neutron flux range
  • Signal filtering with adaptive filter parameters
  • Generation of analog output signals with linear or logarithmic scaling
  • Generation of binary alarm, trip and status indication signals
  • Integrated test-signal generators and simulation capabilities
  • Secured serial interface
  • Qualified for Category A functions (Class 1 system) acc. IEC 61226


The DWK 260 digital wide range channel forms part of the proTK™ product line. It has been designed for continuous neutron flux monitoring during all reactor operation modes.

The DWK 260 channel provides information on the neutron flux, the reactor power and the rate of change of the neutron flux. In addition, it provides binary alarm and reactor trip signals based on the measured neutron flux and user adjustable thresholds. Analog and binary output signals of the highest safety class are available and can be used at the level of the reactor protection system.
