General
 3-axis tower oscillation monitor in compact design
 Redundant system with two independent CPUs and two
oscillation monitors arranged at 45° to each other
 Two integrated safety relays with mechanically interlocked contacts as per EN 50205 class. A switch on
reaching the adjustable limits
 Maintenance and wear-free operation due to MEMS acceleration sensors
 Measuring system is not subject to ageing, is insensitive
to temperature fluctuations, dirt or condensation
 Trigger criterion either evaluation of the geometric sum of
the limits or axis-related evaluation
 Unambiguous hole pattern in the base plate identifies the
mounting position
 Full function in case of condensation: dew-point resistant!
