Bearing Condition Monitor Model XTS-W XTS-W Typical User Interface signal processing unit Combined measurement and display for each cylinder of: crosshead bearing crank-pin bearing main bearing Application l Monitors condition of crank train bearings in large 2-stroke diesel engines l Monitors Bearing Wear (BWM) l Monitors Water in Oil (WIO) l Monitors Shaft Earth Device (SEDM) Key benefits l Open-up inspections can be omitted if an XTS-W system is fitted l Ultimate protection of engine from catastrophic damage l  Reporting and storage of long term trends - can be used as a tool for class surveying l Simple low cost installation - no drilling of highly stressed engine components l Provides signal for engine slow down in case of extreme bearing wear

Bearing Condition Monitor - XTS-W Display and Monitor Unit Screen under alarm conditions • Trend lines using data from selected sensors The Display and Monitor Unit comprises application-specific software, running on a - Wear trend and prediction capability - Alarm/warning indication - Continuous bearing wear status display - Water in oil activity display - Shaft earth device monitoring (SEDM) The use of proximity sensing and the availability of signal post-processing enables real-time wear trend analysis. Through analysis of the rate of change of the bearing condition it provides much...

Bearing Condition Monitor - XTS-W Water in Oil Monitoring (WIO) Engine condition Normal running First alarm level Second alarm level The new generation XTS-W has fully integrated water-in-oil (WIO) and shaft earth device monitoring (SEDM). Separate screens show trends, real-time measurement of Water Activity (aw). Alarm levels are as defined by engine manufacturers. Humidity measurement in oil Similar to the humidity in the air, the water content in oil can be indicated by the relative value aw: - aw (actual water content as a fraction of the water content in saturated oil) - aw = 0...

Bearing Condition Monitor - XTS-W Overview of System Components Proximity Sensors The proximity sensors are robust, proven electronic sensors, which use a low intensity electromagnetic field to detect the position of the guide shoes at bottom dead centre (BDC). The sensors are fixed to custom designed brackets for different engine types. Optional Water in Oil Sensor The water in oil sensor monitors moisture content in the engine’s lubricating oil. Optional Shaft Earth Device Monitor The shaft earth device monitor measures the electrical potential between the propellor shaft and the hull....
