CIP Testing

It is perhaps a good idea to sometimes remind what is CIP Testing.

"CIP" stands for "Commission Internationale Permanente". It was created in 1914 by the Director of the Liege Proofhouse. More: read here.

Reliability record reached

Yesterday we got an e-mail at 15:25 from a customer in France. Their system, including computer, acquisition boards and instruments that we installed in 1999 was down for the very first time in nearly 10 years of good operation. A complete reinstall was needed.

We started to assist the maintenance people over Internet yesterday 10 minutes later, immediately uploading all the necessary software right into the exact version that was delivered 10 years ago. On the way we recompiled it with very minor changes with our updated development tools.

The system was up and running today at 14:25 pm precisely. That is less than 11 workhours downtime.

Such maintenance work would not have been possible just a few years ago. For the occasion we used all possible tools available over Internet.

Again, we thank all our customers for their trust throughout the years.

Pressure transducers calibration - an innovative dynamic procedure

The picture above illustrate a custom program used to calibrate pressure transducers, more precisely to dynamically compare the behavior of a working transducer (daily used in production) against a reference transducer. Both are mounted on the assembly, measures take place just as usual but with both acquisition chains in parallel. Then the program computes the linear regression making it possible to apply correctors on the working transducer so that the highest accuracy is always achieved over the time. Calibrations can be compared from week to week (the frequency depends on the case). By doing this, we see when a transducer falls below limits and needs to be ditched.

Kistler instruments


We can provide our customers with all Kistler instruments available in the catalog.
If you have question or looking for a solution, please ask us.
We can assist you choosing the right equipment and incorporated it into a customized quality control system.

Our software includes a module to remotely control the Kistler amplifiers (especially the 5015A) through an RS232/USB connection.

Acquisition electronics:

The electronics is based on state-of-the-art National Instruments acquisition boards and peripherals. Upgrade from older electronics is possible as long as the output signals are standard (please ask us for checking)

Signals conditioning :

National Instruments signal conditioner with built in electronics for :
  • Triggering on firing pin, pressure rise, muzzle flash or velocity1 start.
  • Velocities signals crop to TTL level.
  • Pressure channels connection and shielding.
  • Forwarding of "chain ready" signal for proper timeout operations.
  • Interfacing to acquisition board via USB to computer.
National Instruments acquisition board :

This board is mounted in the dedicated acquisition enclosure:
  • Pressure sampling up to 1.25 MSamples/sec. Can be set into one of the following configuration :
    • One channel 1.25 MSamples/sec for ultra high accuracy R&D measurements.
    • Two channel 500 KSamples/sec for normal compliance testing.
    • Two channels 500 KSamples/sec for analysis on secondary manometer (only for CIP laboratories).
    • Four channels 250 KSamples/sec for various studies with multiple transducers.
    • 8 to 12 channels - 250 KSamples/sec for various studies with multiple transducers ("flute mounting" 2 or 3 boards may be required required).
  • One timer for action time - resolution 80MHz - Quartz accuracy 50ppm.
  • Up to 3 velocity timers - resolution 80MHz - Quartz accuracy 50ppm. (up to 3 boards - 12 velocity channels for specific trajectories-velocities analysis).
