Technology: Differential pressure drop leakage measurement

The differential pressure drop measurement method is by far the most widely used. The essence of differential measurement is that it uses a reference volume to test the component. This helps compensate for changes in ambient pressure or temperature as they occur simultaneously on both components. Only the leakage on the tested component will be detected.

Another advantage of this method is that accuracy is not reduced as the test pressure is increased, as the sensor measures the pressure difference between two volumes at the same pressure, unlike conventional pressure drop technology, which measures the pressure drop relative to atmospheric pressure.

The conceptual pneumatic design of the F620:

1. ATEQ F620 instrument
2. Internal volume/ piezzo pressure sensor
3. Reference volume
4. Differential pressure sensor
5. Piece of space foam to be checked

The test component (3) and the reference component (5) are loaded to the same pressure, and the differential sensor (4) measures the pressure variation between the test component (5) and the reference component (3) during the measurement cycle. In some applications, the reference component may be replaced by a sealing cap, in which case the reference volume is provided by the internal volume of the ATEQ (1,5 cm3).
