Abstract
A hydrodynamic machine with a turbo coupling comprising primary and secondary wheels together forming a torus shaped workspace, which can be filled with a working medium. A temperature-sensing device installed in a component, which rotates when the machine is operating, and sending a temperature —dependant signal. A stationary monitoring device connected to the temperature sensor in a remote query connection, and having means for creating a temperature measurement correction depending on the heating rate progression of the sensed temperature.

A hydrodynamic machine with a turbo coupling, comprising:
- a primary wheel;
- a secondary wheel;
- the primary wheel and the secondary wheel together forming a torus-shaped workspace which can be filled with a working medium;
- a temperature sensing device installed in a component that rotates when the machine is in operation and sends a temperature-dependent signal to a monitoring device that is connected with the temperature sensing device in a remote query connection and which is assigned to the hydrodynamic machine;
- the signal comprising information for determining the absolute temperature of the working medium and/or a predetermined reference point in the rotating component;
- the monitoring device having a means for creating a temperature measurement correction depending on the heating rate progression of the sensed temperature.
