Application of microwaves for high temperature process monitoring

TL;DR: In this paper, a high gain corrugated conical horn antenna centered at 22 GHz with 4 GHz bandwidth is presented for material process monitoring in furnaces, which is tested in a metal melting furnace.
Abstract: Design and demonstration of a high gain corrugated conical horn antenna centered at 22 GHz with 4 GHz bandwidth is presented for material process monitoring in furnaces. The fabricated antenna is tested in a metal melting furnace. The high temperature RADAR signals demonstrate non-contact level sensing of the molten mass and material property variations with temperature.

TL;DR: In this paper, the class of circularly symmetrical corrugated horns and the parameters in designing are considered. And some basic information for the inexperienced horn designer to get started in designing their CORRUGATED horn is provided.
Abstract: Typical example of horn is shown where the inside wall is manufactured in a succession of slots and "teeth". The purpose of the corrugated surface is to provide the means to support the propagation of hybrid modes within the horn. Hybrid modes are basically a combination of TE and TM modes. Some basic information for the inexperienced horn designer to get started in designing their corrugated horn is provided. The class of circularly symmetrical corrugated horns and the parameters in designing are considered. As an example a standard Ku-band operation from a typical Earth station is also considered.

TL;DR: In this article, a level sensor based on radar interferometry technique is proposed, it is designed to provide high accuracy measurements, high reliability and a very low maintenance, and it is used for the measurement of molten glass level in glass furnaces.
Abstract: Measurement of molten glass level in glass furnaces is a key issue for the control of the production process. Nowadays several different technologies shall be used for this purpose, with their advantages and drawbacks. In this paper a novel level sensor is proposed, it is based on radar interferometry technique, and it is designed to provide high accuracy measurements, high reliability and a very low maintenance.

TL;DR: In this article, an ultrasonic level measurement system which provides a continuous digital readout over a range of 3 to 180 inches, was tested in 500°F liquid sodium and proved to be accurate and reliable, required no initial warm-up period and experienced no long term drift.
Abstract: An ultrasonic level measurement system which provides a continuous digital readout over a range of 3 to 180 inches, was tested in 500°F liquid sodium. The system proved to be accurate and reliable, required no initial warm-up period and experienced no long term drift. Modifications can extend the present operating temperatures to greater than 1200°F.
