Role of Mercury in CMZ-700

1. Supporting the Gyrosphere

   • Mercury acts as the low-friction fluid in which the gyrosphere floats.

   • Its density and fluid properties allow the gyrosphere to maintain stable rotation and precise orientation, minimizing mechanical friction.

2. Damping Vibrations

   • Mercury provides vibration damping, which improves heading stability.

   • Combined with high-viscosity oils and anti-vibration mechanisms, it ensures the compass maintains accuracy even in rough sea conditions.

3. Temperature & Stability

   • Mercury remains stable over a wide temperature range, ensuring consistent gyro performance.

   • It prevents changes in support characteristics that could occur with other fluids.

4. Maintenance Considerations

   • Only the correct type (V8109PN) and exact quantity must be used.

   • During servicing, the gyrosphere and mercury are checked or replaced according to maintenance schedules to maintain accuracy.

   • Handling must follow safety guidelines due to mercury’s toxicity.
