  • Device and method for the status monitoring of a pressure measuring unit
    Patent number: 7284437
    Abstract: 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.
