Monitoring tower vibration and shock

Less sensors
SIL2/PLd certified acceleration sensor GAM900S precisely acquires and monitors tower vibration and shocks. Redundant relay outputs are triggered as soon as the defined limit is exceeded. This 2-in-1-functionality replaces at the same time dedicated acceleration sensors for vibration measurement and mechanical limit switches. The result: Minimizing cost by fewer components and less effort in cabling and logistics.

More safety
According to the EC type-examination of the TÜV Rheinland (German Technical Inspection Agency), the monitoring functionality of the GAM900S is fully compliant to safety integrity level SIL2 and PLd, respectively. This will simplify implementation of the safety function “protection against excessive vibration and shocks” while speeding up safety certification of the installation.
