PLUG & PLAY INTERFACE:
“What You See Is What You Get” WYSIWYG .
ATEQ F6 new interface would almost make the leak testing set up “fun”.
The ATEQ F6 interface is friendly for everyone involved in leak testing:
– A production engineer will find it very easy to set up and remember.
– A user will find it clear to read.
– A quality control engineer will get the datas he’s expecting in no time
– Any training around an F6 will show how easy it is to teach leak detection to new comers … and that’s all thanks to the interface.
FULLY BACKWARDS COMPATIBLE
15 000 ATEQ customers will not throw there older leak tester and replace it with a new one just because it looks good.
One of the most important feature is the ability of the leak tester to plug into existing PLCs and test benchs without having to reprogram everything.
ATEQ’s F6 keeps all its I/O from ATEQ’s previous generations Leak testers.
In addition, the F6 also features more modern interfacing like Ethernet and USB, so customers can be sure that it is also fully “Forwards compatible”.
ATEQ has also released a 3U 19″” version of the F620 called the F670. The leak tester in an industrial standard format which can be mounted in all machines.
Furthermore, we have also designed the F610 particularly suitable for polluted workplaces (dust, oil
etc.) The IP54 waterproof leak tester.
LAB TESTING IN MIND TOO
Again, part of ATEQ’s leak testers’ production goes into quality labs or simply instruments are being set up in labs prior to being installed on production line.
These test conditions require a small unit with a fast and clear interface and gigantic memory to store all the trial parameters and tests.
ATEQ’s F6 has all it taked to feel up those needs.
PACKED WITH FEATURES
SMALL PART TESTING
The ATEQ F6 “MiniValve” is made for small part testing.
In the pressure decay world, volume is the big ennemy. The more volume is filled, the longer it takes to get into the test pressure, to stabilise 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 minivalve that has allowed it to acheive total cycle time (fill, stabilise, 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.
BALISTIC FILL 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 “Balistic fill” does not only fill faster. It also helps stabilising the part’s volume faster.
ATEQ F6 can leak test components up to 80 bars (1250 PSI) in differential pressure mode. That remains unmatched in the industry.
SEALED PART TESTING
Your component is sealed ?
The F6 “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+ develoment engineers team who work all year long with end users to solve real life application issues.
Differential pressure Decay:
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)
Maximum resolution: 0.1 Pascal
Standard pressure decay
The one that started it all
As a stripped down version of the previous technology, standard pressure decay compares the pressure on the part with the atmospheric pressure.
This technology is used when the application does not require a very high accuracy or a very fast cycle time.
Leak Ranges (in Pascal/second): From 10 Pa/sec
Maximum resolution: 10 Pascals
Maximum test pressure: 40 atmospheres
Pressure measurement: 1 % of the pressure + 2 digits and 0.1% of full scale resolution
The most convenient
Often considered as a competitor to the Mass Flow technology, continuous flow relies on a differential pressure transducer and a very precise laminar flow tube to measure leak rates.
Its internal volume ensures that the flow generated by the leak remains very stable over time.
This technology is perfectly suited to the gas industry which sees it as a real time leak reader for gas appliances on production lines.
While the instrument generates a leak and shows its value on the screen, the
operator can tighten the connections of the gas product until it reaches an acceptable leak rate.
Leak Ranges (in cm3.atm/h): 0 to 100 or 0 to 1000 cm3.atm/h
Maximum resolution: 0.1 cm3.atm/h
Maximum test pressure: 50 kPa
Pressure measurement: ± 1% of Pressure + 2 digits and 0.1% of full scale resolution
The one for large leaks
Sometimes a leak can be considered as a “small flow”, or a flow as a “big leak”. When your reject level is too high for other technologies, it may be necessary to use a laminar flow tester.
A flow takes place between the pressure line and the leak hole of the part.
Our instrument features a laminar flow element across which our differential pressure transducer is connected.
Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer.
Leak Ranges (in L/H): 5, 30, 150, 500, 1500, 4000 or 10 000 L/H
Maximum resolution: >1% of full scale
Maximum test pressure: 350 kPa
Pressure measurement: 1% of the pressure + 2 digits and 0.1% of full scale resolution
For those used to Mass Flow meters
The Mass Flow technology converts a mass of air going through a laminar flow element into a leak value. Should the test part leak, a flow will take place between a reference part and this leak, forcing the air to go through the Mass Flow measuring device that will convert it into a leak value such as cm3.atm/h.
However, unlike traditional Mass Flows, our technology can handle “large leaking” parts on the line without having to reset the unit.
And unlike our competitors again, we do not use heating elements to measure the mass of air, thus reducing the sensitivity to contamination.
We’ve also put our expertise in high pressure testing into the pneumatics of this unit, allowing it to measure with a high level of accuracy at test pressures of up to 20 Bar (300 PSI).
Finally, our Mass-Flow technology comes with the latest temperature compensation feature making sure you get the best results in the industry in the toughest conditions.
Leak Ranges (in cm3.atm/min): 2 or 20 or 200 cm3.atm/min
Maximum test pressure: 20 Bar
Pressure measurement: 1% of the pressure + 2 digits and 0.1% of full scale resolution
So far, all the technologies we have described use air to measure the leak rate.
In this case we use electricity.
A high voltage loaded sharp end is applied next to an earth connected base and in between lays the plastic part we test. Should a hole exist in the part, ions will start moving from the earth to the sharp end.
This will result in a loss of power and be translated into a leak.
While this method does not quantify the leak rate in terms of cc/min for example, it is the fastest ever invented to detect a leak in a go / no go process.
We have achieved cycle times of less than 7/10 of a second.
Leak Ranges: Depends on the size of the hole and the material of the part
Accuracy: Depends on the size of the hole and the material of the part
Standard features of our instruments can be completed with optional accessories that will enhance your test station and in most cases make you save time and money.
4 remote controls available:
– The 2 functions TLC.
– The 5 TLC: 2 Functions, 2 Indicators, Increase/Decrease of the programs and displays.
– The onboard TLC.
– The remote display RC5.
Y Valve and Mini Y Valve
The Y valves and mini Y valves are 3/2 spring recoil valves with pneumatic or electric control.
They offer a high level of protection against leaks.
CDF: Leak / Flow calibrator
The leak / flow calibrator allows the checking of the calibration of leak and flow measurement instruments, as well as calibrated leaks and jets.
This portable, compact and user friendly instrument is essential for checking the accuracy and repeatability of all leak and flow testers.
2 pneumatic outputs
The optional pneumatic outputs (internal or external) are Two pneumatic pulses that are being activated at anytime during the cycle and under pre-set conditions such as: Start of cycle; end of cycle; Good part; Bad part; …Etc. They allow the user to operate simple jigs without having to rely on a PLC.
Thanks to electronic regulators, an instrument can be programmed with a different pressure on each test cycle.
It can also be used as a pre-fill pressure to speed up the cycle time.
The dual pressure option of ATEQ’s differential pressure decay instruments allows the reduction of cycle time through faster fill time.Used in conjunction with the pre-fill software option, the dual pressure raises the test pressure faster than conventional fill times.It also helps reduce cycle on flexible parts.
Calibrated Leak / Jet
The calibrated leak or jet allows the checking of the calibration of leak or flow measuring instruments. Available in standard and customised versions, they simulate an exact leak or flow rate inside the test circuit to check that the instrument detects the right value.
Quick sealing connectors
The quick sealing connectors pneumatically compress a soft rubber cylinder around an internal or external diameter.
Together with the optional pneumatic outputs of ATEQ’ instruments, these devices offer a perfect solution to build fixtures quickly and inexpensively.
ATEQ instrument require a clean and dry operation to remain reliable.
The Ethafilter ensures that the ATEQ operates under the ISO 8573-1 standard.
Winateq is an integrated software which is compatible with our custom windows based applications.
It is easy to install and includes a system configuration back up.
It can also be used as a base to develop customised applications. (Import and export function to spread sheet application).
Connected to the RS 232 port of ATEQ’s instruments, this thermal printer can print results in ASCII format, including the details of cycle times and results.
Very handy in laboratory operation to automatically print dozens or hundreds of results.
