Small Part Testing
The ATEQ® “Mini-Valve” is made for small part testing.
In the pressure decay world, volume is the big enemy. The more volume is filled, the longer it takes to get into the test pressure, to stabilize and to test the part.
For small parts (up to 5cc) the absurd situation is that most of the volume tested is in the pipes and internal pneumatics of the instrument.
A standard ATEQ® valve is already twice as small as the nearest competitor. But ATEQ® has gone further with its mini-valve that has allowed it to achieve total cycle time (fill, stabilize, test, dump) down to 0.2 sec for leak rates as low as 0.5 cc/min.
This is the crown jewel technology of ATEQ®. Not only does it compensate for temperature variations, but it learns from the results it gets and adapts itself to those results in a smart way.
Ballistic Full Feature & Electronic Regulator
Again, this feature is an ATEQ® exclusivity. In some applications, filling the part takes more than 1/3 of the total cycle time. ATEQ® has this innovative feature that will let the electronic pressure regulator open fully for a small amount of time, so the part fills up faster. The “Ballistic fill” does not only fill faster. It also helps stabilizing the part’s volume faster.
ATEQ® Primus can leak test components up to 80 bars (1250 PSI) in differential pressure mode. That remains unmatched in the industry.
Sealing Part Testing
Is your component sealed?
The Primus’ “Sealed component” can test it.
What is so special about sealed components?
With pressure decay leak testers, the problem isn’t so much to find a small leak in a sealed part, but rather to detect a gross one. If the component has a big leak, then the internals will get filled at the fill stage, leaving no pressure to drop once the instruments gets into the test stage. ATEQ® has invented and patented the sealed component technic by performing a volume test prior to leak testing your part. So if there is a gross leak, the volume will be higher than expected and the test will fail.
The range of ATEQ® Leak Testers can be fit with as many as 6 different technologies. Most Leak Testing companies around the world claim that this or that technology is better than the others … and they are all right. Each technology is best suited for specific applications but ATEQ® is the only company that masters them all.
Furthermore, ATEQ® has improved each of these technologies thanks to its 50+ development engineers team who work all year long with end users to solve real life application issues.
The most popular
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.
Leak ranges (in Pascal/second):
From 1 to 5000 Pa/sec pressure drops (Values in cm3.atm/min depend on the test volume)
