Function parametrization applied to capacitive pressure sensor response time

The response time associated to monitoring pressure sensors, can be estimated from a set of measurements based on power spectral density of pressure fluctuations (PSD). Surveillance and predictive analysis methods are important for achieving a monitoring of pressure sensors. The function parametrization method is an information treatment technique, that allows setting a relationship between a set of measurements, or input (in this case the frequencies associated to the real and complex poles appearing in the PSD), and the physical parameters, or outputs (response time) of a system (the pressure sensors). These measurements and response time proceed from a database, subjected to a statistical analysis which yields a new response time calculation. Consequently, sensor response time can be estimated from the database, without performing any further noise analysis. (author)
