ATEQ Premier Pressure Decay Leak Testing Equipment
In this video, Jim from ATEQ USA demonstrates the use of the Premier MF. He also explains why a differential leak tester is a superior choice in leak testing equipment.
In the first section, Jim gives an overview of the program parameters. These are only accessible to a physical key holder. Once locked, this ensures the credibility of your testing efforts as no one can change the program parameters. The program parameters he reviewed are:
- Fill time measures the pressurization time of the part.
- Stabilization time measures the time to stabilize the pressure in the part before completing the test. This is done to make sure results are repeatable.
- Test Time – how long the unit monitors the pressure drop.
- Dump (or venting) time measures the length of time required for the part to go back to atmosphere
- Pressure unit of measurement
- Max and Min fill pressure – this is important in case someone mis-adjusts a regulator or the shop air supply is lost. In either of these circumstances, you could not continue with the test.
Differential Leak Testing
Jim also reviews the quick connector for calibrated leak for calibration testing. The Premier MF provides a very precise flow at a given pressure. Therefore, you can use the calibrated leak as a quick calibration check of your leak testing equipment. Also, you can correlate a pressure decay to a flow measurement.
Why use a differential leak tester, and why is it a good feature? Instead of having just one port connected to your product, we’ve added a second for reference. This could be connected to sealed tube or master part. By having a reference port, we can balance the system out, shorten stabilization time and use a very sensitive transducer to measure pressure decay. The Premier MF has a sensitivity pressure decay of 1/10th of a pascal. Consequently, this allows us to find very small leaks, very quickly.
