Mathematical models and hardware & software for highly accurate electronic temperature meters

Optimal mathematical models accurately describing the dependence of thermometric parameters of sensors within the range of operational temperatures were suggested. Circuit and design concepts, and also algorithms and hardware & software implementing the developed mathematical models in electronic temperature-measuring instruments were developed.

Electron Thermostating Elements for Controlling Consumption of Heat Transfer Agent in the Heating Systems

Electron thermostating elements (ETE) mounted on the regulating radiator valves are developed. ETE are designed for the automatic controlling of the consumption of heat transfer agent in the heating systems by a special program. So, ETE are intended for the controlling of the temperature in the heated placements. ETE have autonomous power supply. Optimization of the working algorithm of ETE in conjunction with the high efficiency of the servomotor, and low level of power consumption of the electronic circuit allowed authors to increase the time of autonomous work of ETE. Proposed design solutions of ETE can be used also in different fields of science and technology for the automatic controlling of the consumption of liquid and gaseous agents.

Investigation and Calibration Methods of Precise Temperature Sensors for Controlling Heat Consumption
