Get More Info Data Sheet


Up to four detectors per DSK 250™ channel (LPRM):

  • Individual detector supply
  • Signal filtering and calibration
  • Remote test signal generators
  • RS232/485 data interface for test and calibration

Up to 64 LPRM-signals (16 DSK) per DMK 250™ channel:

  • Calculation of average value and flow related flux signal (APRM)
  • Neutron flux oscillation monitoring
  • Generation of analog and binary signals for the reactor protection system


The DSK 250 and DMK 250 digital power range channels form part of the proTK™ product line. They have been designed for local and average power range monitoring (LPRM and APRM) in the boiling water reactor (BWR). Four in-core fission chambers may be connected to one DSK 250 channel. Hardware and software of the DSK & DMK 250 channels are designed and qualified for applications at the level of the reactor protection system.
