Title: Pvt testing machine
Inventor: KAINO NORIYUKI
IPC: G01F17/00
Filed: 1991-12-03
Abstract: PURPOSE:To make accurate measurement irrespective of the shape of samples by providing a measured temperature value correcting means and reducing the occurrence of errors in measured temperature value resulting from delays in thermal conduction in the samples caused in abnormal temperature states during the heating or cooling process of the samples. CONSTITUTION:When temperature measurement is started after inputting material characteristics and shape characteristics, such as the dimensions, coefficient of thermal conductivity, heat capacity, etc., of a sample in a heat conduction calculating section 7, temperature values obtained from thermocouples are inputted to the section 7 and the temperature distribution in the sample is calculated from an axially symmetric (cylindrical coordinates system) non-steady heat conduction equation by using the measured temperature values as boundary conditions. A temperature averaging section 8 averages the temperature distribution in the sample and outputs the averaged result as a corrected temperature-measured result and the result is stored in a corrected temperature data base 9. Therefore, even when a temperature difference exists between the surface and inside of the sample due to a delay in heat conduction in the sample, PVT data indicating the relations between the pressure and specific volume and between the pressure and temperature can be accurately found by correcting measured values obtained from the thermocouples.
