Types of leak detections

Helium Leak Detector

 A helium leak detector makes use of helium as a residual fuel line while checking out in a closed machine. It has a low atomic mass and chemical stability, giving it exceptional sensitivity while detecting leaks. Since it's miles inert and non-toxic, it's miles a secure and reliable technique for checking out for leaks because it does now no longer have interaction with materials withinside the machine.


A helium leak detector, additionally referred to as a mass spectrometer leak detector (MSLD), locates and measures leaks the usage of helium as a tracer fuel line. The helium fuel line is added into the machine beneath neath stress, that's measured to decide if there are leaks.
The use of helium leak detectors is associated with vacuum and stress checking out. In the vacuum technique, a pumping machine, roughing or fore fine, evacuates the machine to be examined, and helium is added to find a leak. With the stress machine, the piece to be examined is pressurized the usage of helium. The viability of helium as a leak detector is its capacity to come across leaks that aren't seen to the human eye.

High Voltage (HVLD)

High voltage leak detection is a excessive pace pinhole or dielectric illness detection technique for additives made in excessive pace production. The product to be examined is located among electrodes. One electrode is the floor at the same time as the opposite electrode is extended in voltage. If the fabric being examined is solid, the voltage from the raised electrode will now no longer by skip thru to the grounded electrode, and the product is with out defects.


The excessive voltage technique is able to detecting leaks as small as to 5 microns in diameter. When a illness is detected, a seen arc or spark is produced. For merchandise to be examined the use of this technique, they have to be electric non-conductors and feature enough electricity to face up to puncture via way of means of the voltage discharge. Also, merchandise to be examined can't have complicated or complex geometries.

Hydrogen Leak Detector

Hydrogen leak detection makes use of a extraordinarily touchy microelectronic probe mixed with a non-flammable take a look at fuel line containing hydrogen and nitrogen, that's injected into the take a look at item. The strategies for detecting leaks may be executed in numerous ways. The take a look at item may be located in an accumulation chamber that detects the presence of hydrogen, or a hydrogen probe can experiment the indoors of a take a look at item.


The residences of hydrogen offer numerous blessings for leak trying out. It is a totally mild weight detail with a excessive molecular pace and occasional viscosity, making it clean to unfold at some stage in the examined item and penetrates leaks rapidly. Since it does now no longer stick with surfaces, it's miles a great tracer fuel line for trying out numerous components of an item. Hydrogen is a non-poisonous herbal fuel line that doesn't have any poor results at the environment.

Infrared Open Path Gas Leak Detector

Gas leak detection structures are vital because of the character of gasses and their unstable potential. The important motive of fuel line leak detectors is to test for herbal fuel line or different gaseous substances which have damaged containment from a garage unit or pipeline. Gas leak detectors are an vital a part of protection measures in view that small minute fuel line leaks can cause explosive and threatening conditions.
A fuel line leak detector procedure consists of the usage of sensors that produce an audible alarm while the presence of fuel line is detected. The forms of sensors encompass flammable fuel online sensors, photoionization detectors, infrared factor sensors, electrochemical sensors, and semiconductor sensors.
