Abstract
In a device for measuring the temperature in a dust carrying gas stream having a temperature probe and a deflecting rod enclosing the probe at least partially and structure mounting the temperature probe and the deflecting rod within the gas stream substantially transversely to the flow direction an arrangement is provided to increase the operational safety. This is achieved on the one hand in that the deflecting rod is provided on its side facing away from the flow direction with a recess open towards the surface of the deflecting rod and that the temperature probe is arranged in the recess without contact with the wall of the recess and/or in that on the other hand within the deflecting rod substantially in parallel to the temperature probe and in spaced relation thereto at least one longitudinally extending channel filled with a fluid under pressure is provided, which is arranged seen at least in the flow direction of the gas stream a predetermined distance in front of the temperature probe and that the channel is connected to a pressure sensor.
