Leak Testing of Charge Air Cooler

InterTech's Mass Flow Leak Detectors are Superior
There is actually a wide range in the capability of mass flow leak detectors one finds in the marketplace. The sensors used in mass flow leak testers vary in quality. Some manufacturers merely take standardized sensors and fit them into one or more instrument models. However, if the sensors are customized components in instruments, and selected for functioning in the ranges that are most important to the specific leak testing application, they can improve speed and accuracy. This is the proven and superior InterTech approach to mass flow leak testing.

A second consideration is how the instruments are calibrated and how their standardization is validated. If an instrument relies on mechanical devices for calibration they are subject to much greater variation in testing results when compared to InterTech's calibration and validation using solid state technology. Solid state technology also minimizes equipment breakdown or need for repairs.

Thirdly, mass flow sensors also vary in terms of how they compensate for temperature variations. This is particularly important when leak testing newly cast prototypes that may still be warm from a casting process. In these instances, either time must be added to allow the parts to cool to room temperature, or the mass flow has to be calculated taking the temperature variation into consideration. InterTech's mass flow leak test instruments automate temperature compensation and some do not.

InterTech�s ISO 17025-compliant automated systems, instrumentation, and applications engineering for leak testing and functional testing and assembly and test --

Decrease leak test and functional test cycle times between 25% - 70%

Save up to 10% in product development costs

Cut time-to-market by up to 15%

Guarantee gauge R&R of ENTIRE assembly and test systems, not just instruments

In this leak testing application, high pressure and low pressure charge air coolers are sequentially mass flow leak tested and marekd a t a rate of 20 pph per station.

Charge Air Cooler Leak Testing Highlights

FEATURES

An InterTech M-1075 Mass Flow Leak Detector, controls the leak test cycle.

High pressure and low pressure charged air coolers are (a href="http://www.intertechdevelopment.com/capabilities_detail.cgi?id_num=2">leak tested. (Coolant side is leak tested to a 3.0 sccm limit at 269 kPa. Air side is leak tested to a 20 sccm. limit at 379 kPa.)

Transducer in the mass flow leak detector operates in a self-check, fail-safe mode.

BENEFITS

Automation: Leak test station is designed to be robot loaded and unloaded.

Speed: Mass flow leak detection technology permits the fast and accurate leak testing of large volume parts. Quick pass testing accelerates accept/reject decisions.

Traceability: Programmable marking allows part traceability.
