Method and apparatus for detecting and monitoring states

A condition detection and monitoring system for the at least intermittent, possibly periodic, preferably even ongoing, value-, signal-or data-based detection and monitoring of condition parameters of at least one assembly or component, for example of a bearing or a slewing ring in or on a wind turbine, comprising:

• at least one, preferably more than two, contact sensors which are attached to or incorporated into said assembly or component,
• and which can preferably be directly or indirectly attached or incorporated at or in an incorporation site located, for example, on a planar or rounded surface or a contour of said assembly,
• and which can usefully be attached or incorporated by screwing/insertion/welding/brazing/adhesive bonding or clamping, possibly to a nose ring or a support ring or retaining ring of a large rolling bearing,
• and, alternatively, which can be attached or incorporated at or on at least one radial or axial inner or outer surface of a blade bearing, main bearing or tower bearing of a wind turbine,
• wherein the at least one contact sensor is directly or indirectly connected or connectable to at least one evaluation unit or evaluation module, particularly to an electronic evaluation unit, by value-, signal-or data-based technology for the purpose of relaying signals/data/values,
• wherein optionally at least one secondary sensor, which is not a contact sensor, also is directly or indirectly connected or connectable to said evaluation unit by value-, signal-or data-based technology for the purpose of relaying signals/data/values.
