EQUIPMENT FOR PROTECTIVE MONITORING AKV-03/1




Purpose:

Monitoring and emergency protection of industrial machinery (turbogenerators, pumps, compressors etc.). Information about machinery vibration state is to be given to the operating and maintenance personnel. The modular approach to the equipment structure permits the system to be created in accordance with the object special feature.

Application:

The -equipment measures, displays and registers vibration characteristics and mechanical parameters regulated by normative documents touching on the equipment protection, gives the operating personnel the information, required for analysis and state estimate of the equipment.
