Crankcase protection system CPS

About the product

The Crankhouse Protection System (CPS) is designed to monitor the bearings of 4-stroke diesel engines. A thermoelectric measurement between the rotating shaft (e.g. via brushes) and the engine block is converted into a signal (CPS signal) as an indication of the engine condition.

The Crank-Case Protection System (CPS) is designed for monitoring bearings of 4-stroke Diesel engines. A thermoelectric measurement between the rotating shaft (eg via brushes) and the engine block is transformed into a signal (CPS signal) designated for engine condition monitoring.
The basic principle of the system is to measure the thermos voltage produced by a steel crankshaft when it slides on the metal surface of its bearing shells.
The CPS signal provides information, at an early stage, about upcoming damages caused by friction, especially of bearings. Operators get informed through the display about the condition. Thus, it helps to diagnose failures in those moving parts at early stages, preventing the engine from serious damages.
The system is, in parallel, connected to the AMS system - by pre-alarm and main-alarm relay outputs.
