Abstract
A pressure sensor module for measuring a differential pressure has a sensor chip for measuring a differential pressures and a module housing with at least two lead lines that are disconnected from one another by the sensor chip and in which lines differential pressures are at least intermittently present, wherein in at least one lead line a valve is disposed that closes the lead line when the sensor chip no longer disconnects the lead lines from one another.
Claims12
A pressure sensor module for measuring a differential pressure, comprising at least
- a sensor chip for measuring a differential pressure, and a module housing, which has at least two lead lines that are disconnected from one another by the sensor chip, and in which lines different pressures are at least intermittently present,
- characterized in that
- in at least one lead line (10, 12), a valve (15) is disposed that closes this lead line (10, 12) when the sensor chip (3) no longer disconnects the lead lines (10, 12) from one another.
