measurement of gamma-emitting radionuclide volumetric activity in liquid

Spectrum Analysis Monitor UDZG-211 (.pdf)

Main features and functions:

  • measurement of radionuclide volumetric activity in liquid, and data display (depending on version) or data output via RS485
  • work in spectrometer mode
  • automatic spectrum stabilization against temperature changes
  • adjustment according to required radionuclide composition
  • automatic self-testing, alarm signal generation, alarm signal display and alarm output via RS485
  • three alarm thresholds programming (warning and two emergency thresholds), signal alarm in case of considerable measured value variation
  • "dry-contact" signal of threshold value is exceeded
  • standard (0...20mA / 4...20mA) analog output for measured data transfer to external systems
  • standard (0...20mA / 4...20mA) analog input for external device connection and its measured data consideration in algorithms
  • pumped medium monitoring and consumption measurement
  • unified and replaceable components for all "RADSYS" system devices
