Precise acceleration information for maximum control
Precise acceleration measurement provided to master control via CANopen or analog interface
Prevent the system from exceeding a defined level of vibration
Reduce excessive vibration before reaching critical amplitudes
MEMS sensors with ultimate precision at minor deflections and minimum axis cross-talk
Ideal for precise vibration monitoring, for example at wind turbine towers
User-configurable filters eliminate interference for more precision
Support to eliminate vibration interference caused by acceleration sensor installation at solid, load-bearing machine parts
Integrated deep or band pass filters up to 8th order

Concept supports consequent implementation of the European Machinery Directive 2006/42/EG
Ideal sensor to fulfil safety function "protection against excessive shocks and tower vibration" required at wind turbines
Sensor integrated signal processing and limit monitoring function to eliminate control-implemented safety-rated embedded software (SRESW) or application software
Limited number of components and easy integration
SIL2/PLd certified sensor GAM900S merges vibration measurement and funtionally safe limit detection function in one device
Replace common standard shock and vibration sensors and cut down wiring effort
Analog or CANopen interface for communication to standard master control
Easy integration into safety chain via redundant relay output contacts
Applications
Precise detection of acceleration and safe vibration monitoring at all kinds of machines and installations, for example tower vibration and shock impact at wind turbines.
Technology
Detection reliability by diversified redundant sensors
GAM900S utilizes two precise MEMS sensors which reliably detect shocks and vibration, for example at wind turbines:
The diversified redundant sensors provide the required system capabilities to identify common cause errors
The components are sourced at different manufacturers, come in different designs and in addition utilize different methods of signal processing
Safe software certified according to IEC 61508-3
From specification to validation, the safety-rated embedded software (SRESW) implemented in the GAM900S fulfills all requirements of the safety standard IEC 61508-3:
Extensive tests and documentation of the safety-related software
Guaranteed non-interaction of safety-related software with standard software, for example for CANopen communication
Confirmed by TÜV Rheinland: the high requirements for the safety integrity according to SIL2 / PLd are fully met
