Abstract
In order to improve an expansion installation for obtaining electrical energy from heat by means of a thermodynamic circulation procedure, comprising an expansion device, which is operated by an expanding working medium of the thermodynamic circulation procedure, and a generator driven by the expansion device, it is proposed that the expansion installation should be provided with a rotational speed sensor, which is coupled to a shaft of the expansion installation that rotates proportionally to a rotor of the generator, and which takes the form of an electrical sensor generator that generates an electrical sensor signal.
