A big-end bearing seizure can have expensive consequences for an engine and for your business. The Wärtsilä Wireless big-end bearing temperature monitoring system provides real-time temperature monitoring of the connecting rod big-end bearings. If the temperature exceeds acceptable limits, it enables preventive actions to be taken to avoid expensive repairs and lost revenue.
In the worst-case scenario a big-end bearing seizure can lead to complete engine failure. For example, the crankshaft can be damaged to the extent that it needs to be replaced altogether. The Wärtsilä Wireless big-end bearing temperature monitoring system provides crew with real-time data on the big-end bearing temperature and enables automatic load reduction and shutdown in case of big-end bearing temperature deviation.

The system consists of a wireless temperature sensor with one stationary antenna per cylinder and one or more signal processing units. The temperature sensor is installed in the connecting rod, while the stationary antenna is installed in a suitable place inside the engine crankcase. A coaxial cable connects to the signal processing unit. The unit can be connected to a standalone alarm and monitoring system or to the engine automation system.
