Bearing Distance and Temperature Monitoring System
Bearing Distance and Temperature Monitoring System why
Why ?BDMS provide an early warning in case of starting warning in case of starting bearing failuresBDMS will reduce operational costs by avoiding scheduled opening of bearingsBDMS is a step from time based to condition based maintenanceBDMS is a step to safe human resources

Bearing Distance and Temperature Monitoring System
Bearing Wear Monitoring principle
At the bottom dead centre (BDC) the journals of all 3 bearings (main, crank pin and crosshead) are loaded.The inertia forces are downwards looking, no gas force is affecting the system.An instant detection of slowly or emerging bearing wear is carried out, indicated and recorded in the indication panel. A prediction of the remaining lifetime of the bearings is possible at any time.It is also possible to indicate with utmost plausibility which one of the bearing (main, crank pin or crosshead) is affected.

Bearing Distance and Temperature Monitoring System
Bearing Wear Monitoring principle
Bearing Distance Monitoring System
The system measures continuously the distance between the crosshead location in the bottom dead centre (BDC) in relation to the engine
1
relation to the engine frame at 2-stroke Diesel engines by means of 2 sensors per compartment (sensor A and sensor B). The measured values are calculated into real distance values in mm by the sensors and stored in an internal memory inside the sensors.
