Patented Leak Detection Testing

Since 1992 InterTech patented leak detection testing has paced developments increasing accuracy, speed, Gauge R&R, reliability, and convenience in production-line leak, flow, and functional testing.

1992 US Patent 5,161,40  Advanced Mass Flow Sensor

Enhances the technology of dry air leak testing in factory environments by maintaining high measurement accuracy across a wider range of air pressures and temperatures, ambient temperatures, and random, short-duration disturbances in measured airflow.

1994 US Patent 5,363,689 Simple, Convenient Electronics Calibration

InterTech's CalMaster obsolete fragile, cumbersome soap film flowmeters and rotameters offering a rugged, advanced user adjustable, portable hand-held, electronic alternate that displays leak or flow rate continuously in digital read-out format with no user judgement or calculations needed.

1996 US Patent 5,546,789 Bias Flow Leak Testing

InterTech's accuracy-sharpening technique couples "downstream (belljar) testing with a known preliminary airflow that confirms a leak-tight belljar seal or sets a known leak reference. This allows true test part leakage to be measured more precisely in less time and is especially helpful in testing to low leak limits.

2001 US Patent 6,279,383 Hydraulic Fluid / Dry Air Testing 

InterTech's technique for using air pressure rise to measure hydraulic fluid leakage significantly improves accuracy and repeatability by eliminating the variable effects of bulk modulus (fluid compressibility) that distorts conventional test methods relying on fluid pressure measurement.

2002 US Patent 6,442,550 Hydraulic / Pneumatic / Extending Clamp

InterTech's design combines a compact body with a 2" reach and 1000 pounds of clamping force. These features shorten part-to-part cycles by allowing ample clearance of loading parts into fixtures, and extending to apply the clamping force needed for effectively sealing the part.

2003 US Patent 6,626,027 Nuclear Magnetic Resonance Testing

InterTech's technology for measuring leak rates down to 10 to the minus 11 sccs uses hyperpolarized helium-3 as a tracer gas detected by applying a magnetic field and radio frequency excitation, then measuring resonant electromagnetic frequency emitted by the He-3 nuclei. A promising alternative to helium mass spectrometry, NMR testing offers shorter test cycle times, insensitivity to temperature variation or false detection of other environmental gases and impurities plus elimination of costly vacuum equipment and time-consuming
maintenance associated with mass spectrometry.
