Patent number: 7284437Abstract: The invention relates to a device and a method for the status monitoring of a pressure measuring unit in an absolute or differential or relative pressure transducer, a pressure-sensitive element installed in the pressure measuring unit being impinged with at least one pressure generated by at least one membrane. During a defined diagnosis time interval, a testing element integrated in the pressure measuring unit is induced to undergo a change in volume, preferably by electrical activation. The pressure difference caused as a result in the pressure measuring unit is registered by a pressure-sensitive element. The curve registered during a diagnosis time interval is compared with a reference curve recorded with the pressure measuring unit intact. A fault indication is given if the deviations between the registered curve and the reference curve exceed predetermined tolerance values.Type: GrantFiled: April 12, 2005Date of Patent: October 23, 2007Assignee: ABB Research LtdInventors: Peter Krippner, Wolfgang Scholz, Peter Riegler, Emrullah Altiok, Jürgen Biskup, Wilhelm Daake, Raiko Milanovic, Rolf Merte, Armin Gasch, Fabrizio Lorito, Andrea Moroni, Franco Vecchiato, Corrado Bianchi, Eugenio Volonterio
