| dc.description.abstractother | The technique to restore temperature impulse shape from thermocouple measurements is proposed. In most cases to measure temperature the contact techniques are used. Thermocouples are one of the most widely used temperature measurement devices due to their robustness, ease of manufacturing and low cost. However, thermocouple using in harsh environment requires the increasing of wire diameters and consequently the measurement bandwidth is reduced. In many applications signal restoration techniques are needed to recover the true temperature from the attenuated measurements. Also, many applications require the availability of fast response temperature sensors. To remove the thermocouple effect on the measurement results the compensation method is proposed. Compensation involves two stages: thermocouple identification is followed by the temperature reconstruction. Reconstruction is a process of restoring the unknown temperature from thermocouple outputs using deconvolution technique. Deconvolution is made in time domain. This paper describes compensation technique based on deconvolution to address loss of high-frequency signal components using the measurements from thermocouple. In particular, filtration of thermocouple output signal and restored signal is proposed. The result clearly shows that the inclusion of signal filtration increases signal to noise ratio. This technique does require a priori knowledge of the thermocouple impulse response function. The quality estimation of the thermocouple input signal reconstruction is obtained. The effectiveness of deconvolution method in time domain for solving the inverse problem of determining the temperature impulse shape is demonstrated. | uk |
