A new method about the air temperature reconstruction based on the block correction interpolation was put forward. Its theoretical basis is the principles of thermodynamics relations and ultrasonic temperature measurement. The frequency of ultrasonic generator is 40 KHz. Because of the one-to-one relationship between gas temperature and gas velocity, the gas temperature field can be reconstructed through the rebuilding of velocity field. As the distance between the generator and receiver is known, so the average speed on the path can be obtained by detecting the ultrasonic transit-time. After obtaining the average speed of many paths in the field, the correction of the measured data can be done by using the block correction interpolation technology. And through the mathematical analysis software, the reconstruction of the measured field was given.

Key Parameter

Temperature is one of the most important key parameter to consider in measurement and mechanical engineering, because every measurement has to be conducted with reference to standard temperature conditions (20 °C, ISO 1). Strictly speaking, almost every measurement depends on the accuracy of the temperature measurement, which requires proper calibration. Therefore, standards list detailed criteria to fulfil temperature calibration with high precision. In fact, any calibration is only valid, if the whole measurement chain is taken into account. This would make recalibration necessary with each variation of the components in the measuring set-up (varying cable length, different measurement channel etc.), which is time-consuming or even impossible in practice. For that reason, this paper presents a practicable calibration strategy, which specifies each component individually and later combines the calibration results according to the composition of the measurement chain. This provides a fast and useful way to achieve the required accuracy of temperature measurement. The examined, exemplary measurement chain consists of an industrial platinum resistance thermometer (IPRT), cables with different lengths, an electrical amplifier and a reference temperature calibrator.

The analysis of the nonlinearity of the transfer function of primary temperature transducers based on transistor structures has been performed. It’s shown that the quadratic component of the transfer function creates a significant nonlinearity error up to 0,2-0,6°C. We have developed methods of linearization based on both the formation of compensatory measuring current and change of the conversion factor of the output scaling amplifier at certain ranges of temperature measurement, which ensure their use in precision temperature measuring devices. The measurement error does not exceed 0.01°C in the range of 30-100°C.

Fiber Optic Temperature

Fiber optic temperature sensors offer unique advantages when used to measure cutting temperature in machining processes. This paper presents novel miniature fiber optic temperature sensors and their application in cutting temperature measurement in Rotary Ultrasonic Machining (RUM) of titanium. The sensors were based on a Fabry-Pérot (FP) interferometeric principle. The endface of the fiber was wet etched. A piece of borosilicate glass was thermally deposited into the cavity on the etched endface to form an FP cavity. Temperature calibration experiments were performed. During RUM, the sensor was embedded in the titanium workpiece to monitor the temperature change using different ultrasonic power. The results demonstrate the advantages of fiber optic sensors including high accuracy and resolution, superior stability and repeatability, and good durability against harsh environment.
