A new system for PV-plant monitoring is presented. The system allows the fault detection in each module of a PV plant. For that, electronic circuits are connected in parallel with each PV module sensing voltages around all the components. An extra current generator can modify slightly the current in one string introducing current in parallel to a selected module. A simple and efficient module model,...
A new hardware-software interface for autonomous sensors has been designed with the objective of providing a low power consumption and high performance interface for the measuring of transduction elements commonly used in industrial applications: temperature, resistive bridges, accelerometers, capacitive and pressure sensors. It integrates a Generic Transducer Interface, which is an analog front-end...
We present some strategies to reduce transmission losses and increase the operating range of a position sensor based in the magnetostrictive delay line principle. They include the saturation of the sample to reduce the magnetoelastic coupling far from the emission and detection points. The experimental set-up for a prototype of such device is described and some results presented. The inhomogeneties...
