About the sensor. 

The Siri Marine Trim Optimization tool uses a MEMS-based accurate and reliable inertial measurement sensor. High data quality is ensured through temperature calibration from -20 to +50°C for bias, gain, cross-axis, and linearity. Its solid state design, combined with its rugged stainless steel enclosure, ensures reliable operation in most environments.


  • High accuracy acceleration measurements - Ingress Protection IP67 
  • Easy plug and play setup - connection cable up to 250m
  • Elegant aluminium - no separate power supply or robust stainless steel enclosure required
  • Optional ATEX certified or subsea enclosures
