As well as our turbine supervisory equipment,we supplyseismic sensors for
power plants.For many,particularly
nuclear stations,monitoring earth movement is as
important for safety reasons as monitoring the turbinesthemselves.Sensonics are the leading supplier of Seismic Monitoringand Protection systems to the UK Nuclear Industry.We
offer a range of equipment,which can be scaled to meet
the most complex requirements.Integrity and robustness
is key to our system concept,offering protected power
supply configurations and custom indication panels as well
as alarm voting racks suitable for safety critical
applications.The systems provide a secure and extremely
dependable seismic alarm to the site operational staff,
allowing rapid shutdown of plant processes in a
controlled manner. Annunciator – For local alarm indication and resetfacilities.Key operated interlocks and alarm defeat Recorder
The key system components are as follows:- – Robust PC with embedded operatingsystem,contains on board non-volatile memory for
program operation and event data storage. Qualifications - Seismic qualification to IEEE Std 344-1987,EMC approval to Def Stan 59-41. Calibrator UPS – Typically configured in a dual redundant PSUconfiguration and available with various hold up times
dependant on system load. – Activates individual
transducer self testfacility for complete system integrity check. Voting Rack - Offering multi-channel ‘two out of three’alarm voting.Utilising either robust electromechanical
devices or triplicated programmable logic with self-fault
diagnosis.
