AB  - The paper proposes a method and device for on-line temperature measurement with Pt-100 sensor operating in a nonlinear mode. The sensor measures the temperature in range of 00C to 2000C, whereas the measured data are processed by applying a two-bit stochastic digital measurement method. The proposal is theoretically analyzed and tested experimentally. It is shown that the accuracy of the method depends on the accuracy of the sensor. At a sampling frequency of 1 MHz, the maximum accuracy is reached in 17.5 sec. and is equal to 0.015% of full scale (FS). On the other hand, when the measurement time interval is 0.1 sec. (the shortest measurement interval), the accuracy is equal to 0.1% of FS. Therefore, the proposed device can be used for both calibration and measurement purposes.

AB  - In this paper we present the model of digital stochastic DFT processor. Compared to the classical DFT/FFT processors, the proposed model has two advantages: first, it is much simpler and cheaper to implement, and second, it allows us to compute individual DFT components either in isolation or in parallel. In order to prove the validity of our model, we have simulated the measurement of reactive power and energy. In addition, we have conducted several experiments under field and laboratory conditions. The obtained results have shown that reactive power and energy can be measured with an accuracy of several ppm. © 2018 Elsevier Ltd

AB  - This paper considers the process of analog signal reconstruction measured by using a two-bit stochastic digital measurement method. The proposed process is tested by digital simulations on the example of a triangular signal. It is shown that for sampling frequency of 10.58 MHz and measurement interval of 1.28 s the precision (effective resolution) of the reconstructed signal is 12.18 bits. If one wants to achieve a more precise reconstruction, it is necessary to increase the measurement time interval and/or sampling frequency.
