Apparatus for the rapid measurement of temperatures in a hot gas flow

摘要

The apparatus has a sensor (20) with two two-dimensional, electrically conductive heating units which are attached to a surface of a common, electrically insulating sensor body (19). The body is cylindrical and extends along an axis, where the units are disposed on opposite sides of the surface of the body relative to the axis. The sensor is surrounded by a radiation shield, which forms an annular channel together with the sensor.
