# Notification sensor arrangement for a differential pressure sensor and a method for outputting a sensed warning signal

## 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.
