A monitoring system for monitoring parameters representative of operating conditions of an oil film bearing, wherein an oil film is present between a static component and at least one rotating component both defining an axis X, said at least one rotating component being arranged inside said static component and adapted to rotate about said axis X, the monitoring system comprising
- at least one pressure sensor to detect an oil pressure of said oil film;
- at least one distance sensor to detect a distance between said static component and said at least one rotating component and thereby a thickness of said oil film;
- at least one temperature sensor to detect a temperature of said oil film;
- characterized in that the at least one pressure sensor, the at least one distance sensor and the at least one temperature sensor are housed in said at least one rotating component.
