температура

Standards of physical quantities are used for reproduction and storage of physical units as well as for transfer its size by appropriate measuring instrument. The temperature is an intense value and is determined only indirectly depending on certain physical quantities of temperature, for example, resistance, thermoelectric power and so on. This situation has led to the fact that there are several temperature scales, each of which has its unit of temperature measure.

The improved method of compensation the influence of the lead wire resistance for two-wire resistance temperature detectors (RTDs) on the basis of commutation inverting of the reference measuring currents is proposed. For the averaging of signals generated as a result of commutation inverting of reference measuring currents, predominantly low-pass filters are used. Their usage limits the speed of temperature measurement.

Are ways electrical frictional cutting billets by friction circular saws. The features of thermal phenomena in the processing and developed a mathematical model for calculating the contact temperature in the cutting zone, which takes into account complex thermo-physical conditions and modes of processing, thereby allowing control of processes of heat generation and the quality of the machined surface.
