AbstractAbstract
[en] A simple and convenient system used to measure the workpiece temperature fast and exactly for plasma source ion implantation (PSII) is developed. The method of dynamic workpiece temperature measurement using double thermocouples is introduced. The experimental results indicate that the method can measure exactly the workpiece temperature. This low cost system possesses excellent stability and gives precise measurements

AbstractAbstract
[en] In process instrumentation systems of such as nuclear plants, response time information is very important in most temperature transient measurements. Generally the response time of thermocouples is measured at a laboratory by using a plunge method. However, it is not easy to use the plunge testing method when a response time measurement of an installed thermocouple is required. A measurement system was developed to measure the response time of a thermocouple installed in a process by using the Loop Current Step Response(LCSR) testing method. This device heats a thermocouple by providing an electrical current, and then it measures the thermocouple output as the temperature of the thermocouple measurement junction returns to ambient temperature. The time constant of the thermocouple is determined from the transient curve of the thermocouple output indicating the temperature difference between the reference junction and measurement junction of the thermocouple. The device is designed to heat a middle point to reduce the temperature error caused by residual heat of thermocouple wire

AbstractAbstract
[en] The purpose of this study is to prevent the stick, scuffing, scratch between piston and cylinder in advance, to obtain data for duration test in actual engine operation. The temperature gradient in cylinder bore according to coolant temperature were measured in use of 1.5 liter class gasoline engine 20 thermocouples were installed at points of 2mm inside from cylinder wall near top ring of piston in cylinder block, which points have suffered major thermal loads and suggested as proper measurement points for engine design by industrial engineers. Under full load and 70 .deg. C, 80 .deg. C and 90 .deg. C coolant temperature conditions, temperature of cylinder block, engine oil, exhaust gas in exhaust manifold, fuel consumption and engine performances were measured. The results obtained are summarized as follows : 1) The temperature in cylinder block and engine oil increased gradually in according to the increase of coolant temperature. 2) The siamese side temperature of top dead center is 142 .deg. C in peripheral distribution, it is about 20 .deg. C higher than thrust, anti-thrust, rear side temperature, 3) The fuel consumption in 70 .deg. C coolant temperature is lower than 80 .deg. C, 90 .deg. C coolant temperature. 4) The engine torque in 80 .deg. C, 90 .deg. C coolant temperature condition is about 0.5kg.m higher than 70 .deg. C coolant temperature

AbstractAbstract
[en] Medium-surface temperature of black, gray, and white plug sheets was measured with thermocouples and an infrared camera. During the night, there were no medium-surface temperature differences between the plug flats; however, medium-surface temperature was 2 to 3 °C below air temperature. Medium-surface temperature increased as solar radiation (280 to 3000 nm) increased. About 80 W of solar radiation/m2 was incident on the plug-flat surface before medium-surface temperature equaled air temperature. Medium-surface temperature in the black, gray, and white flats was 6.3, 6.1, and 5.3 °C above air temperature, respectively, when 300 W of solar radiation/m2 (30% of the maximum solar radiation during the summer) was incident on the medium surface. Thus, incident solar radiation has a greater effect on medium surface temperature than plug-flat color. (author)

AbstractAbstract
[en] We present a high temperature heat oven with merits of conventional heat pipe oven and study ots thermal characteristics. The oven consists of stainless steel body and heating part of three layers of ceramic tubes. We obtained the maximum temperature of about 1350. deg. C at the center which was measured by thermocouple and infrared thermometer. And we compared the heating characteristics in the cases of external heating and no extent heating. It was applied to self diffraction experiment in the samarium gas which was one of the high melting point material.

AbstractAbstract
[en] Testing was started on February 24, 1998 and completed on February 25, 1998. The completed procedure consists of 4 acceptance test sections, 6.1 through 6.4. Three test exceptions were identified during the procedure. The first test exception was determined to be unrelated to the ATP and unfortunate that the instrument failed during the ATP. The next two test exceptions were disposition as acceptable because the alarming functions worked correctly in identifying a problem when software communications were interrupted. The test was completed satisfactorily over 2 days. The remainder of the acceptance test report is the completed test procedure

AbstractAbstract
[en] The glass industry, with support from the U.S. Department of Energy (DOE), undertook a project to significantly improve temperature measurement in glass melters, thereby reducing energy usage through improved process control. AccuTru International determined that a new kind of protective sheath would improve the life and range of applications of the temperature measuring thermocouples. In cooperation with Corning, Inc., the University of Missouri-Rolla ceramics department conducted tests on a proprietary alumina sheath technology, which shows significant promise. In addition, AccuTru obtained DOE funding to develop a self-verifying sensor. The new sensor, with alumina sheath, was tested at a Corning facility, and the results exceeded expectations. Areas for additional development efforts were identified
