Abstract: A sensor system including a sensor probe configured to house one or more coils of resistive electrical wire, an electrical circuit configured to energize each coil so as generate heat within the sensor probe and receive output signals from each coil, the sensor probe comprising a heat transfer material designed to facilitate heat transfer between the sensor probe and a surrounding medium surrounding the sensor probe, and a processing unit configured to measure the output signals from each coil to determine changes in level, temperature, and/or flow rate of the surrounding medium based on changes in the output signals.

Abstract: An online monitoring system for industrial processes, such as nuclear power processes, including a data acquisition unit configured to sample output signals simultaneously from a plurality of process sensors, and a computing unit configured to record sampled output signals from the data acquisition unit and to cross-correlate the output signals from two or more of the process sensors to diagnose operation of the industrial process, identify loose parts and/or degradation of industrial plant equipment, enable virtual sensing, calculate sensor response time using the noise analysis technique, and to verify sensor calibration using the cross calibration method and/or empirical and/or physical modeling.
