Ioniq - Plastic part high speed leak tester
What's new in leak detection for high speed production testing
In order to respond to the needs of manufacturers with a high output rate, ATEQ, a world leader in the field of air/air leak testing on the production line, has developed a new leak detection instrument for plastic parts : the IONIQ.
This new process allows leak testing on plastic parts by measuring discharge current. The IONIQ detects faults in the order of about 10 µm and can test up to ten parts per second. This is the ideal instrument for systematic high speed testing of bottle tops for faults at the point of injection, and of plastic or sealing membranes for thickness defects.
Technical brief:
- 2 possible configurations (1 measurement channel or 1 to 6 measurement channels)
- Measurement of discharge current
- 30 kV high voltage generator
- Inputs and outputs (control and results)
- Reject levels expressed as a percentage of a reference voltage
- Monitoring and protection of the voltage generator
- Limitation of output current
- Maximum size: H x L x D = 420 mm x 300 mm x 160 mm
- Weight: 6.5 kg
- 1 year guarantee

High pressure leak tester
BREAKTHROUGH IN HIGH PRESSURE LEAK TESTING
A unique high pressure instrument, with an astounding pressure drop measurement accuracy of 1Pa at test pressures up to 50 bar, has been developed by Ateq
Date: 16 October 2000 News from: Ateq Product: FHP leak tester
There is good news for production and project engineers who have previously tried unsuccessfully to source accurate pressure decay leak testers for pressures above 15 bar! A unique high pressure instrument, with an astounding pressure drop measurement accuracy of 1Pa at test pressures up to 50 bar, has been developed by Ateq, worldwide leaders in pressure decay leak testing technology. Catheters, refrigeration parts, oil coolers, high pressure tubes and valves, and many other products can now be leak tested accurately and cost-effectively at high pressure with the Ateq FHP. Ateq has devoted considerable development effort to the production of special valves and pressure transducers for the FHP instrument which, for the first time, enables highly accurate and reliable dry testing for components and assemblies designed to operate at, or be capable of withstanding, high pressure. The Ateq FHP can be used in manual, stand-alone test stations or is readily incorporated into special purpose machinery and automated production processes, with PLC interfacing. With 32 programmes as standard, the instrument is capable of multiple sequential tests or multiple product testing, and produces a clear pass/fail test result. A comprehensive range of options and sealing connectors, developed through Ateq's extensive application experience and expertise, is available to meet individual needs precisely.

CDF - First multirange leak / flow calibrator
New calibrator introduced by Ateq
A newly developed leak/flow/pressure test calibration instrument, designed to provide a versatile and convenient method of maintaining accuracy on all types of leak and flow testing equipment is introduced by ATEQ alongside the company's comprehensive range of pressure decay test instruments.
The new ATEQ calibrator simplifies and improves the accuracy of test instrument calibration procedures, further increasing the convenience and efficiency of pressure decay, leak and flow testing thus helping to ensure quality of production.The instrument complements the use of calibrated leaks and removes the need to have all calibrated leaks recalibrated - they can now checked regularly in-house using the new ATEQ calibrator. Multi-range leak, pressure, atmospheric pressure and temperature measurements are undertaken. Four measurement ranges cover leak rates from zero to 2000 cc per minute (an exceptionally large range) and pressure is measured from -1 to 10 bar. Numerous functions are available in the standard instrument versions including RS232 and infrared interfaces, conversion of measurement units, results storage, time/date function, multiple languages and a facility for automatic measurement to standard conditions to eliminate the effect of variations in environmental conditions.
Technical brief:
- Adjustment of the leak thanks to a needle valve
- Measurement between 0 cm3 and 2000 cm3/min, accuracy < 3% of the value measured
- Pressure measurement between -1 bar and 10 bar, accuracy < 1% of the value measured
- Ambient temperature measurement between + 5 °C and + 45 ° C, accuracy 1% of the measured value
- Measurement according to normal or operator defined conditions
- Infrared and serial RS 232 ports
- 4 line alphanumeric display
- Simultaneous or separate display of the pressure, the flow and the temperature
- Carrying out of a pre-programmed verification sequence (10 tests maximum)
- Time stamp
- Unit converter
- 2 built in languages, English as standard with a second as chosen (German, Spanish, Italian, French or Portuguese)
- Maximum size : H x L x D = 345 mm x 192 mm x 85 mm
- Weight : 3 kg
- 1 year warranty

Autodiagnostic valve - Self calibration device for ATEQ F3
Users of pressure decay leak test machines generally carry out regular checks, mostly every shift, sometimes more often, in order to make sure that the whole system is working correctly. The most widespread method is to use a so-called Master part, which is a dedicated part that is known to be absolutely leak free. This part needs to be put on the fixture, then, a first test is launched to check the "zero" of the machine. Next, a calibrated leak needs to be plugged into the test circuit. This is a specially manufactured capsule containing sintered metal powder, that has been compressed in such a way that when submitted to a given test pressure, it passes a controlled amount of air, which simulates a leak in the part tested. This leak rate is a known value, measured by the manufacturer and stated on the Calibration Certificate supplied with the calibrated leak, e.g. 4 atm.cm³/min at 20 psi. Another test cycle is started, and the person performing the verification checks that the value the instrument displays at the end of this test has not changed from its usual value for this test. Although this calibration check remains mandatory, it is labour-intensive, disturbs the normal production process, and is a tedious task, as most of the time it just confirms that there is no anomaly. Also, the calibrated leaks need to be re-measured regularly, as any contamination or even shocks (drops) will affect their leak rate, which adds to the inconvenience of this method.
ATEQ has now developed a feature, which can be easily automated, and which reduces the frequency of these checks, without calibrated leaks and on any production part that passes the normal production leak test successfully. The "Auto-Diagnostics valve" feature consists of a special valve, including a small chamber of adjustable volume. When the Auto-diagnostics input is activated, the instrument will carry out a normal test cycle, but after the leak rate measurement it will open this AD valve, which will produce a known increase in the volume of the test circuit. This volume increase will generate a certain pressure drop, called the AD pressure drop. This pressure drop will be measured and automatically compared to the previously stored AD value. If the new value is within the tolerance, the instrument gives out the normal Pass signal and the production process carries on as normal. If the value is outside the tolerance, an alarm light comes on to alert the operator (or the PLC). A further investigation can then be undertaken.
The benefits of this feature are huge:
- Qualified staff's time is no longer wasted on routine checks, as they are only called out when there is a real problem.
- The check can be easily automated, e.g. to be carried out every X cycles, without the need for human intervention (on automatic stations). For manual stations the operator just needs to press a button to launch this check, and as it is easy, and does not take up valuable production time, it will actually be done.
- No need to re-test large quantities of parts anymore when a problem does occur, if for instance the procedure is to do an AD test for every new bin of parts, only one bin will be dubious.
This feature is available on the ATEQ F differential pressure decay tester range, and can be retro-fitted to existing instruments. For more information, contact ATEQ UK, tel. 01908-261060 or fax 01908-261960.
