Abstract:
This article introduces an experimental approach to evaluating the thermal resistance of industrial resistance temperature sensors and demonstrates their use for estimating the flow rate of the surrounding medium. A new method, the Self-Heating Effect Anemometry (SHEA) method, is proposed. Experimental studies were conducted for various flow rates (up to 6 m/s) and excitation current values (up to 5 mA) to evaluate the thermal properties of the sensors under dynamic operating conditions. The results obtained show that the proposed method can be effectively used to select an appropriate measurement current that minimises the self-heating effect and keeps the temperature measurement error within an acceptable range. At the same time, the method allows one to determine the flow rate of the surrounding medium from the measured thermal resistance of the sensor. The presented approach can be applied in both precise temperature measurements and flow monitoring systems using thermoresistive sensors. The proposed method simultaneously provides measurements of both the temperature and the flow rate of the surrounding medium. The research contributes to a better understanding of the self-heating effect in industrial measurement applications and provides practical guidance to improve measurement accuracy and sensor operating conditions.
