ABSTRACT

A notification sensor arrangement includes a drift pressure sensor measuring a
drift signal indicative of a drift of a differential pressure sensor. The
drift pressure sensor has a drift sensing unit formed on or in a symmetrical
diaphragm, which has an upper side in fluid communication with a first fluid
having a first pressure and a lower side in fluid communication with the first
fluid having the first pressure. The notification sensor arrangement includes
a comparing unit comparing the drift signal with a predefined threshold value
to determine if the drift of the differential pressure sensor is a critical
drift, a notification unit outputting a warning signal in response to a
determination of the critical drift, and a base supporting the drift pressure
sensor and the differential pressure sensor.
