Temperature Measurement by Modified Na D Line Reversal Method
Search this article
Description
An automatic recording pyrometer fitted for the pyrometry of working gases in the rocket engine has been constructed. Two methods of pyrometry are established in the present pyrometer : the first is of Na D line reversal type (self-balancing method) and the second is of its modified type (non-balancing method). The both methods are performed by using the photo-electric devices and the bichromator. In the self-balancing method, the accuracy of measurement is 30°K at 2000°K and the response time is about 6 sec. On the other hand, the non-balancing method has the accuracy of 10°K at 2000°K and the response time of 0.1 sec, and besides makes it possible to observe the temperature of the gas having a low emissivity. Certain requirements for the spectrum line reversal method are mentioned, and the results obtained by the present pyrometer are given.
