Abstract
Temperature converters based thermal resistance are widely used for measuring temperature. It has a high accuracy of measurement. The typical pattern of the thermal converter is shown in the books. For measuring using metal dependency of resistance on temperature. Basic dimension schema consists of a voltage reference source listed sequentially, thermo resistance, exposed to the action of the measured temperature, and key resistance whose value is known in advance. In this paper the temperature measurement transformer with a simpler scheme without key resistance, and measurement results processing algorithm are presents.
Keywords
thermal converter, thermo resistance, thermal converter without key resistance
