Temperature Measurement System

The article describes the problem of measuring the temperature in a pulse combustion chamber. The object of the study is a valveless pulsejet. The problem is analysed on the example of exhaust gases temperature measurement. The measurement in these conditions requires the use of a sensor resistant to large changes in gas velocity and temperature and at the same time with adequatly low inertia. This excludes the use of fast and precise yet thin, resistant wire sensors or ultrafast thin film thermocouples. Finally, a temperature measurement system based on sheated thermocouples was chosen. During each test the thermocouple has its own temperature which is different from the medium temperature. In order to properly determine the measured temperature of flowing media it is necessary to take the sensor time characteristics into account. In this article the iteration method is proposed to solve this problem.

Thin film thermocouples (TFTCs) have vast vistas owing to their advantages, such as thin junction, small volume, fast response rate, high sensitivity and so on. In this investigation, a transient temperature sensor of TFTCs was fabricated to measure the surface transient temperature by vacuum coating technology. Silicon dioxide was selected as insulating substrate, the overall dimension of which was 8 mm long, 8 mm wide, and 0.1 mm thick. Two different metal layers were sandwiched between silicon dioxide 2 insulating substrate and silicon dioxide protective layer: cuprum and nickel films, which were 0.08 μm thick. TFTCs consist of 13 Cu-Ni junctions, which are connected in series. The whole TFTCs area is 4.6mm × 4.6 mm. The aggregate thickness of the transient temperature sensor is 0.17 μm. To protect Cu and Ni films, a silicon dioxide layer thickness of 0.01 μm was evaporated on metal layers excluding terminal points. This research carried out static and dynamic calibration to TFTCs. The Seebeck coefficient of the thin film thermocouple is 0.83843 μV/°C. The dynamic performance of TFTCs exhibited dynamic behavior corresponding to the heat flux change on the surface of thin film thermocouple.
