Abstract
A device for testing a pressure sensor having a pressure-sensitive region includes a fixture for a pressure sensor designed to receive the pressure sensor, a nozzle designed to generate a gas flow interacting with the pressure-sensitive region of the pressure sensor and positioned so close to the fixture such that the nozzle does not contact the pressure-sensitive region of the pressure sensor and a predefined portion of the pressure-sensitive region experiences an increased or decreased pressure relative to ambient pressure which is constant within a deviation of 10% relative to a pressure mean value, and a measurer designed to measure an electrical signal received by the pressure sensor.
