TECHNOLOGY

By far the most popular technology, differential pressure decay uses a reference volume to test your part. This helps compensate for any ambient pressure or temperature variations as they occur on both parts simultaneously.

Only a leak on the test part will result in a movement of our transducer’s membrane.

The second advantage of this method is that the accuracy does not drop with the test pressure as the transducer is measuring pressure differences between the two circuits, as opposed to the traditional pressure decay technology that measures pressure drops against the atmosphere.

DIRECT MEASUREMENT PRINCIPLE

The part under test 3 and the reference part 5 are filled to an identical pressure. A differential sensor 4 measures the pressure variation between the part under test 3 and the reference part 5. In some applications, the reference part can be replaced by a cap.

DECENSITIZED TEST

This mode is used for the measurement of large leaks, when the reject level required is above the full scale of the differential sensor. The test pressure is applied to the input of the part under test 3. The measurement is performed by the pressure sensor 2.
