Abstract
A control device is proposed for the burnoff procedure of a hot wire in a constant-temperature anemometer. The control device ascertains temperature increases elapsing in an uncontrolled manner at the hot wire, for instance occurring as a result of a spontaneous ignition of gasoline fumes, and terminates a burnoff procedure, once begun, upon the occurrence of these uncontrolled temperature increases. These events are ascertained via the signal behavior of the hot wire current and are related to a computer-controlled realization and to an analog circuit layout.
