 The
Beran 768 Condition Monitoring System is an optimised
solution for smaller turbines such as those used in
Hydroelectric and Gas Pumping Installations. In addition,
an alternative configuration utilising a multiplexed
input option is ideal for auxiliary plant applications.
Designed around the Beran 766, the 768 System compliments
the modular design of the Beran range. The system utilises
the same Beran MS Windows Client Software, which provides
full PC control of the Condition Monitoring System.
|
The system can monitor up to 4 tacho signals, 8 AC signals
(32 Multiplexed), 16 local DC channels (up to 256 remote),
8 digital channels and has 8 alarm relay outputs. The
multiplexed variant allows up to 4 plant items to be monitored. |
