Products used in this application:
Leak testing is an important step in many industrial and product manufacturing processes. A part under test may need to meet a certain leak threshold to qualify as a good product, perhaps the leak rate of the product is known and any flow higher would disqualify it.
This example requires precision pressure control and monitors the leak in a part under test with a flow transducer. The QPV is a good choice for this under constant flow (dynamic conditions) application. Pressure in the part under test is held to extremely tight tolerances by the high resolution proportional QPV. The leakage at that pressure is then actively measured by the flow transducer. The smooth, steady control of the proportional solenoid results in an error free flow transducer output.
