Intelligent Sensor Measurement of GTE Gas Temperature with Thermistors

Based on the analysis of the existing schemes and measuring instruments of high temperatures GTE, the article proposes an intelligent system using the developed design of a thermistor made of tungsten-rhenium wire, allowing its installation on the jacks of previously used thermocouples. The calculations of the thermistor, taking into account the dependence of the resistivity change and temperature coefficient of resistance on temperature. Using the conversion functions, the optimal value of the output frequency of the measurement system for transmission over a two-wire communication line with high noise immunity is calculated.
