A measuring device is provided which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured. The surface supports the measuring device. The measuring device comprises at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle. The projecting contact surfaces, when the measuring device is placed on the surface of an object being measured, lie against the surface and are supported by the surface. A first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.

Method for monitoring of a wind power plant operated in variable operating states. Start sensor data is obtained in at least one basic operating state of the machine; based on the start sensor data, a starting model with a rule set for conducting the monitoring is set up, the rule set determining which parameters are to be monitored, in which manner and with which weighting and which sensor data are to be obtained and used for this purpose; a reference SOM is prepared using the rule set with sensor data selected using the rule set and obtained in a reference operating phase of the machine; during a monitoring operating phase, time characteristics of a quantization error of the sensor data selected using the rule set being tracked with respect to the reference SOM, troubleshooting being started if the quantization error meets a criterion which is dictated by the rule set.
