Need to leak test high-voltage automotive batteries a topic for discussion
CHICAGO – INFICON is showcasing the auto industry’s most advanced refrigerant and fuel leak-detection systems at this year’s Assembly Show (Oct. 25-27) in the Chicago suburb of Rosemont.
The company also will be polling visitors to its exhibit (Booth #245) on the need for leak-detection systems to test high-voltage automotive batteries.
“Currently there are no standards for leak testing batteries used on electric and plug-in hybrid electric vehicles,” said Thomas Parker, INFICON’s North American automotive market sales manager. “The industry needs to learn more about the leak-detection challenges that will be facing battery manufacturers, auto suppliers and their customers.”
Technology on display at the company’s exhibit will include INFICON’s Protec P3000 (XL) Helium Sniffer Leak Detector, the Sensistor Sentrac Hydrogen Leak Detector and the HLD6000 Refrigerant Leak Detector. The three-day show for manufacturing suppliers, buyers and users of assembly equipment takes place at the Donald E. Stephens Convention Center.
“Year after year we discuss projects targeted to improve leak detection processes with more and more companies,” Parker noted. “The automotive, medical and aerospace industries are all under pressure to manufacture and guarantee leak-free products.”
INFICON’s Protec P3000 (XL)® Helium Sniffer Leak Detector is designed for demanding production environments for testing components in refrigerators, freezers, air conditioners, automotive air conditioners, engines, RAC components and similar products.
The device provides quick results to make the best use of available cycle times and is both easy and comfortable to use. Protec P3000 (XL) also can detect leaks from a considerable distance and is able to measure the lowest detectable leak rates possible.
A small display in the detector’s ergonomically-designed probe handle shows leak rates so that a technician can concentrate on the sniffing process while monitoring leak rates at the same time. A built-in illumination source on the probe helps insure precise positioning of the sniffer tip and multiple alarm functions ensure that alarms cannot be overlooked.
The Protec P3000 (XL) leak detector’s maintenance-free sensor uses innovative INFICON Wise TechnologyTM. Combined with a unique design and the ruggedness of the detector, the sensor provides low cost of ownership and high up-time.
Manufacturers can cover a wide variety of test requirements with INFICON’s Sensistor Sentrac® Hydrogen Leak Detector. The sniffing device can handle manual and robot-assisted leak detection in environments with high levels of tracer gas, providing both selectivity and sensitivity.
Looking for leaks with diluted hydrogen tracer gas is an ideal solution for a variety of industrial applications. INFICON’s Sensistor Sentrac was developed for improved operator-friendly use. A pressure-sensitive color touch screen provides a user interface with clear logical functions. It also makes settings simpler for various measuring situations and minimizes the risk of time-consuming errors. In addition, settings for a variety of measuring situations can be saved as configuration files and stored on an SD card for safe backup.
Sensistor Sentrac delivers leak-detection results immediately on both desktop and battery-operated models. The ergonomically designed probe handle delivers fast access to frequently used functions through a multi-function button. Probes can be used in rough environments that are wet or dusty. During leak testing, LED lights in the probe illuminate and precisely pinpoint leaks.
The INFICON HLD6000 Refrigerant Leak Detector builds on the success of its predecessor, the HLD5000, with an updated hand probe that is more ergonomic, lighter, more flexible and more maneuverable. A new touch-screen display also uses a more intuitive interface and provides easy-to-understand icons with fewer menu levels. Probes are available to detect leaks of R-1234yf, R-134a and CO2, as well as many other refrigerants.
As under-hood and interior space becomes increasingly tight, the HLD6000’s slim probe with twin LED illuminators makes it easy for operators to correctly place a probe in poorly lit areas to precisely locate leaks. Optional flexible probe tips also are available. Colored LED status lights alert the operator to device status, excess leakage detection and possible errors or warnings.
The HLD6000 has a proven long-life highly-sensitive infrared sensor and responds quickly to refrigerant leaks. Its dual inlet system compares background refrigerant to measured refrigerant at the sniffer tip to minimize false alarms and more efficiently pinpoint leaks.
The HLD6000 connects into local networks with a variety of analog or digital interfaces through an optional I/O module. The USB interface provides data transmission to a connected flash drive, and its gas reservoir for a COOL-Check reference leak is stored in a “garage” beneath the main unit for quick replacement.
A unique Bubbleizer display also featured at the INFICON booth provides a side-by-side comparison of leaks of 0.01, 0.1, 1.0 and 10 sccm (standard cubic centimeters per minute) in water-filled glass cylinders. Parker noted that a crack 15 microns wide by 1.5 mm long leaks at a rate of 0.003 sccm and is undetectable with a water-bubble test. The same leak can be easily found with a helium leak detector.
For those interested in learning more about leak detection, Thomas pointed out that INFICON recently published a 51-page e-book entitled “Leak Testing in the Automotive Industry: A Comprehensive Guide to Leak Detection”. It is available free-of-charge from the company’s website.
