High Temperature HXW Sensor
This article introduces a new type hightemperature HXW sensor, which bases on the theory of black body radiation. The sensor consists two parts:detective cannulation and detective apparatus. It takes the advantage of both contact and contactless temperaturemeasuring method. This method is using artificial black body to keep contact with the measuring object, which is made of a type of high temperature resistance and corrosion resistant material. The photoelectric detector can receive the radiance signal of black body when black body has been warmed up to the same temperature as the measuring object. By this method we can measure the practicaltemperature of all kinds of high temperature oven or liquid, and things like that.
