Description
The DGK 260 digital power range channel forms part of the proTK™ product line.
It measures the neutron flux and reactor power in the power range, in combination with neutron ionization chambers. In addition, a fast current output signal, directly from the input amplifier is provided for external systems that monitor for characteristic fluctuations (noise) on the current signal.
Hardware and software of the DGK 260 channel is designed and qualified for applications at the level of the reactor protection system.
