A sample chamber is arranged within the measurement head. An opening, which is free of any restrictions and which is in communication with the sample chamber, is formed in the end face of the second end of the measurement head. The sample chamber includes a first thermocouple having a first thermocouple junction enclosed within a wall which has a uniform internal geometry. A ratio D/H of an internal diameter D of the sample chamber to a length H extending between the opening and the first thermocouple junction is between 0.1 and 1.2.

摘要： A method and apparatus for timely and accurate measurement of material parameters are disclosed. A test sensor measures the temperature of a sample of material as it is heated up and/or cooled down. A reference sensor is used to obtain differential temperature measurements as the temperature of the test sample is varied. A differential temperature trace is generated and analyzed in order to determine various characteristics of the material being tested. In one embodiment, the sodium fluoride to aluminum fluoride ratio (NaF:AlF3) and alumina concentration in a Hall bath aluminum smelting operation are determined in order to efficiently control smelting of aluminum metal. In this embodiment, bath temperature and liquidus temperature may be measured and compared in order to determine the amount of superheat of the bath and to prevent the operation of smelters at higher temperatures than necessary.
