Helium leak testing is generally more sensitive than using pressure decay techniques. Pressure decay also does not allow you to pinpoint the specific location of the leak using a tracer gas. Pressure decay also does not allow you to pinpoint the specific location of the leak using a tracer gas.
View products detecting Helium gas Gascheck G leak detector GasCheck G is a handheld gas leak detector for the rapid, effective detection of gas leaks providing reliable and stable readings of almost any gas or gas mixture.
For leak testing applications that have a reject leak rate too small to accurately detect with air leak testing instruments, your best choice for measurable and repeatable leak testing results is with Helium leak testing. Helium leak test instruments can detect leak rates down to 1×10-10 sccs and beyond.
This chapter examines the various current and future uses of helium. The current applications are divided into the main categories used by BLM to track domestic helium usage in 1996 (): cryogenics, pressurizing and purging, welding, atmospheric control, leak detection, breathing mixtures, lifting, and other uses.Each section will discuss the application for which helium is used, the reason for ...
Put the test piece, which has been filled with helium gas, in a bell jar or a chamber. Vacuum the chamber or the bell jar with roughing vacuum pump and connect to a helium leak detector. Any leaks will allow helium to escape and be detected. Application: fire extinguishers, air bag inflators etc.
HVS Leak Detection has a full line of helium leak detectors available for rental that can meet any industry and application need. We have new, used and rebuilt helium and hydrogen leak detectors for rent. We can provide portable leak detectors, compact leak detectors, and full consule and bench top model leak detectors for rent.
background helium, difficulty with iso lation of the leak-ing tube, and sometimes leak indications were appearing where no helium had been sprayed. This led to an initial determination that tracer gas leak detection in condensers might prove to be ineffective. However, perseverance triumphed. Successful Application of Helium Technology
The INFICON UL1000 Mobile Helium Leak Detector is designed to meet the most demanding industrial leak detection applications. Providing fast, accurate and repeatable test results, testing flexibility, and high sensitivity in a low maintenance design, the UL1000 is ready to tackle the toughest leak detection jobs industry can offer.
HVS Leak Detection provides leak testing services in shop or on-site for a wide range of customer needs. We can quickly locate even the smallest leaks in any pressure system, vacuum system or hermetic system across a wide range of industries and applications.
Helium Connectivity Solutions are simple to deploy and scale but we understand that sometimes you may have questions specific IoT application that need a little extra attention. For those situations, Helium offers a variety of support packages to meet your needs.
Micro-Flow Technology introduces a new dimension in leak testing. Unlike pressure decay, it offers a breakthrough in leak testing with short cycle time, temperature stability, and low measurement ranges that could only be achieved with helium mass spectrometry in the past.
Each of the mentioned examples gives a legitimate description of leak rate but the generally accepted unit is the last one because of very simple and understandable helium leak detection. Its efficiency is the result of a fierce and highly competitive developments within the last 15-20 years.
A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. ... It still requires the part to be tested to be connected to a helium leak detector. The outer surface of the part to be tested is sprayed with a localized stream of helium tracer gas.
One industrial application for helium is leak detection. Because helium diffuses through solids three times faster than air, it is used as a tracer gas to detect leaks in high-vacuum equipment (such as cryogenic tanks) and high-pressure containers.
low background noise and makes helium a very attractive gas for leak detection applications. In addition, helium is: • readily available on a worldwide basis. • not toxic or flammable • an inert gas. Helium can be easily obtained in cylinders of various sizes and only needs to be of welding-grade purity. The application…
The leak detection testing stations fullfil wide range of requirements from line production testing to prototype and newly developed pruduct testing. State-of-the-art technology and field-tested vacuum pumps and detectors are implemented in the testing stations.
Helium Leak Detection System . Application. In helium leak testing, a test part is pressurized with a helium/air mixture in a test chamber. The test chamber is then evacuated so that helium is allowed to pass through any leakage points in the surrounding vacuum.
Phoenix Magno Helium Leak Detector-the leak detector for production applications requiring a larger dry scroll roughing pump or rotary vane pumps. Phoenix Vario Helium Leak Detector-the leak detector for production applications where an external pump is chosen to match the application.
In terms of cost of ownership, real application performance, ease-of-use, and more—the Agilent Helium Leak Detector is setting new . standards for confidence. Because leaks are inevitable. The Agilent Helium Leak Detector. 4. The Agilent HLD: innovation and confidence.
ORS manufactures the HSHLD ® Model 310 High Sensitivity Helium Leak Detection System, a Quadrupole Mass Spectrometer system for High Sensitivity Helium Leak Rate measurement to qualify your product to the latest, tighter leak rate requirements of Mil-Std-883, Method 1014.
In this sample application, the helium gas usage is 393.7 CFH. If we assume 2 shifts per day the helium consumption is 6300 cubic feet. If the cost of bulk helium at $10/100 cubic feet, the daily cost of helium is $630. At these levels the purchase price is recovered in less than two years. We also feature a very attractive leasing arrangement.
