The development of optical fibre temperature indicator using epoxy glue as a detection membrane is presented. This study, investigates the effects of epoxy glue from the reaction of epoxy resin, bisphenol A (BPA) (80-05-7) and adhesive epichlorohydrine (ECH) (106-89-8) as a temperature indicator membrane. In this work the response of epoxy glue to excitation source 395 nm is tested and analyzed under cryogenic conditions. A fiber optic temperature sensor for detecting ambient temperature ranging from 15 °C to 80 °C has been examined. The epoxy glue fluoresce when excited with UV-blue light source. The intensity of the fluorescence of the material decreases when the epoxy glue is exposed to an environment of higher temperature. These decrease level of fluorescence signal has been used to indicate temperature. In this paper, the basic principle of operation, development process and emission response characteristics of this sensor are discussed.

ABSTRACTThis paper reports the response characteristics of rf-sputtered SnO2 thin films (of varying thickness) for LPG detection. To monitor and precisely measure leakages, the development of a reliable LPG sensor with improved sensitivity is crucial in preventing fatal accidents. In the present study, thin film of SnO2 is used as the sensing element for LPG sensor. The thickness of a thin film is a very important parameter and determines their main operating characteristics, such as sensor response, rate of response, and working temperature. In the present study, thickness of SnO2 film is varied between 30 nm to 180 nm. The structure, composition and optical properties of SnO2 thin films have been examined by XRD, SEM, AFM and UV-Vis. The crystallite size for 90 nm thin film (for (110) plane) is found to be the smallest ~4-5 nm. Sensor response $(S = \left( {{{R_a - R_g } \over {R_a }}} \right) \times 100\% )$ increases with thickness of the sensing film, with a highest sensor response (~67%) observed for 90 nm thin film and thereafter it decreases. The structural and optical properties clearly support the observed enhanced sensor response for 90 nm thin film.

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.

Measuring Devices

The response of temperature measuring devices to pulsating flow fields has been a source of concern to compressor designers. A conventional temperature sensing device is known to respond to the highly energetic wake flow leaving a rotor and due to the long thermal time constant of the probe a temperature lying between the hot wake temperature and the relatively cooler main stream temperature tends to be indicated. This indicated temperature can be in serious error if included in a calculation to define the energy flux. This work is concerned with a theoretical and experimental examination of temperature sensor response to an unsteady pulsating flow typical of that occuring in a compressor.
