Features

  • 10 to 12 decades of measurement range with one detector only
  • Calibration into neutron flux units (nv, P/Pn)
  • Filtering of the signal with an adaptive time constant
  • Calculation of the relative flux change rate (reciprocal of the reactor period) for the whole wide range
  • Generation of analogue and binary signals for the reactor protection system
  • Remote test signal generators, even in the preamplifier
  • The correct function of all signal paths can be tested before start-up
