Purpose:
continuous gamma dose rate measurement

Main features and functions:

  • measurement of gamma dose rate, and data display (depending on version) or data output via RS485
  • automatic self-testing, alarm signal generation, alarm signal display and alarm output via RS485
  • two alarm threshold levels programming (warning and emergency levels)
  • alarm of measured value "minor change"
  • "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
  • detecting unit can be installed at a distance up to 60 m from processing unit
  • unified and replaceable components for all "RADSYS" system devices.
