Abstract: | In this paper we propose a feedback system, with thermoresistive sensor, based on sigma–delta modulation. This system uses an one-bit sigma–delta modulator in which considerable part of conversion functions is performed by a thermoresistive sensor. The sensor is modelled using the power balance principle and the applied measure method is constant temperature. This transducer architecture is able to perform digital measurement of physical quantities that interacts with the sensor: temperature, thermal radiation and fluid velocity. This paper presents simulation results of this system applied to thermal radiation measurement. |
