CIS AMREIN ⇒ DDx type dual Coil based Pendulum Transducers
The DD2,DD3,DD6 and DD8 pendulum transducers perform the measurement of the differential expansion on turbogenerators and similar rotating machines. The DD5 pendulum transducer performs the measurement of the shaft axial position. The
The basic principle of operation is a suspended magnet which follows a shaft collar displacement. The sensor element is a pair of accurate coils, measuring the displacement of a target plate. The slim and vertical design of a DD2 transducer allows its mounting on the machine at relatively narrow locations.The rugged design and the continuous further development of the transducers assures a reliable and accurate measurement over the life time of a machine.
Compared with other measurement systems, the pendulum transducer principle allows the translation of the measuring point to a more protected (steam leaks) and cooler area, which minimise also the temperature effect on the measurement.
Furthermore, the actual measurement is performed onto a target made of reference steel, avoiding measurement discrepancies due to various steel qualities, as may occur with direct measurements onto the shaft. Dedicated DD-transducer interfaces are standard in all CIS AMREIN monitoring systems.

CIS AMREIN ⇒ CAVAS Vibration Monitoring, Analyse and Diagnostic System
CAVAS provides a complete solution for vibration monitoring of rotating machines.
Individual, multi-channel, distributed acquisition and processing subsystems (RMDAS P4700 units) are connected using standard networks to one or more database processors (Linux based) providing access to both real-time and historic data.
Typically turbine-generators and other main plant units have their own devoted RMDAS subsystems providing each unit with its own individual continuous on load, run-up and run-down monitoring independent of any other unit.
Other less critical auxiliary rotating machines may be grouped together to be monitored by a single RMDAS subsystem.
The RMDAS units receive the syubsystemsem
Each RMDAS unit maintains its own database on its internal disk so that it is independent of any other subsystem, network or similar.
Data is available on Windows PCs over LANs, WANs and modems for display in a variety of graphical and numerical forms.
Access by modem or VPN, is available by means of dial up networking and also directly through a CAVAS Admin PC.
CAVAS provides comprehensive alarm checking, mimics, trends, vector plots, orbits, FFT’s, waterfalls and so on for real time and historic data.
As well as acquiring vibration data (dynamic signals) from the protection systems (VMDS II, RKK) or sensors, each RMDAS unit may also directly capture plant process data (statics) to allow correlation between vibration levels and plant condition.
Because it is networked CAVAS often receives plant process data from other computers via network. |

CAVAS Benefits:
• Improved safety by decreasing the risk of machine failure.
• Continuous machine health information allows predictive maintenance,
avoiding and limiting machine damage.
• Reduced capital costs by extending machine service life.
• Decreased machine servicing costs by only repairing or replacing those
parts which are damaged or worn out.
• Decreased machine repair costs by recognising problems before they cause
serious damage.

service.
• Reduced risk of unplanned shutdowns by allowing scheduled maintenance
to coincide with production requirements.
The benefits of monitoring rotating equipment with vibration sensors and process parameters are well known

CAVAS Data Presentation:
CAVAS user may view data collected by CAVAS on any PC or workstation on the network with the CAVAS User software installed. There are numerous displays available. The CAVAS User interface is powerful yet easy to use for casual users. It is a graphical user interface where selection of display type and channels is by mouse selection from pull-down or pop-up menus. |
| The CAVAS User interface was designed in conjunction with power plant control room engineers. CAVAS provides a number of graphical interface modules for specific functions. |
Operator module provides mainly real-time data displays such as Mimics, Trends, Waterfalls, Orbits.
Historic displays data from the historical database.
Prodem is for diagnostics and displays full frequency spectra and
time histories
Config is a configuration editor |
| CAVAS supports a number of different levels of access on a per user basis, typically Expert, Engineer and Operator. This allows the system manager to control who can access configuration settings, create new layouts, change screen setups and the like. |
| |
CAVAS Data Storage:
Data is continuously acquired and displayed by CAVAS. Data is also saved to disk for long-term storage and historical presentation. For time-based states such as Onload or Barring then the user defines the logging rate to disk. For variable speed states such as runups or rundowns then all data is saved to disk. Data is stored in binary, fast-access, formatted files which maintain a “first-in first-out” cyclic storage scheme. A database is also maintained to provide pointers to significant events within this file structure such as start of events, alarms, startups and shutdowns so that data may be easily retrieved later.
Each RMDAS system contains a sufficiently large hard disk to allow several years worth on data to be stored online. The archive system also contains exchangeable media for backup or archive, typically a magneto optical disk. Data is written to this media on a daily basis as a backup. The amount of space available on this media is reported to the users and they are warned when it becomes full. This distributed database system allows a user to access data regardless of where it is stored.
Data may be extracted from the CAVAS database and file system.

CIS AMREIN ⇒ CAVAS Lite Portable Analyse and Diagnostic System
Non_Current Electronic Systems
CAVAS Lite is small enough to fit into a standard flight bag and rugged enough to withstand typical Power Station environment.
Data can be acquired synchronous to a once per revolution tachometer signal to provide high accuracy harmonic and subharmonic measurements. Alternatively, it can be time-based for slow speed conditions or where a tachometer signal is not available.
A standard signal conditioning module allows inputs to be taken from accelerometers, velocity or displacement probes.
CAVAS Lite supports up to 24 inputs, which may typically be configured as 16 vibration inputs together with 8 plant analogue signals. The system detects plant operating conditions such as Onload, Overspeed, Runup, Rundown, Barring and Slow Roll and adapts its acquisition technique accordingly.
Typically access will be via a Notebook computer running Windows and using an ethernet connection. Using this connection CAVAS Lite may be configured and set to work, thereafter the Notebook may be taken away and the system may be left unattended to collect and store data to its internal disk.
The CAVAS Lite ethernet connection is available on the back panel. CAVAS Lite may be connected directly to a Desktop or Notebook PC. |
