Leak detectors are used to pinpoint the source of a
leak. Gas and vapor leaks are common in virtually any industry. In fact,
it is a simple truth that anything that uses gas will leak. The concerning
factor, however, is how fast the leak occurs, whether it be a small amount
by the second or every thousand years. When the amount that is leaking
becomes a potential danger for the equipment or the health of the employees,
leak detectors are used to determine the amount and the composition of
the gas being leaked. When this is done, a corresponding action is taken
to deal with the leak accordingly.
Leaks can be found via electronic, chemical and sound-sensitive technologies.
Most leak detectors are hand-held devices that are programmed to monitor
specific conditions. The mobility of the leak detectors is important because
of the tight and complex networks of piping that are sometimes used to
house a gas or a liquid. Most methods of leak detection are operator dependant.
Some systems, however, such as those used to detect water leaks, are able
to monitor changes in atmospheric conditions without the use of an operator.
Different types of leak detectors are used for specific duties, such as the
actual gas detection at the spot of the leak, the amount that is coming
out and the type of gas. Sometimes a tracer gas like helium is used to
help aid in the detection of other gasses.
Leak detection and prevention is a crucial part of the industrial sector.
Many different industries have problems with leaks, and thus need reliable
and accurate leak detectors to fix their problems. In the medical industry,
leaks can be found in pumps, containers, fluid transfer devices and other
instruments that may play a crucial role in the lives of patients. Other
industries, such as the scientific and automotive, use leak detectors
on measuring equipment, waterpumps, cylinder heads, calibrated volume
vessels and hydraulic components. Having problems with leaks can not only
cause a system to malfunction, but could also be hazardous to health,
depending on what chemical or gas is being dealt with. Because of this,
leak detectors play an important role in many fields today.
Unfixed leaks are a major source of economic loss in both the residential
and industrial spheres of society. Leaking liquids and gases can damage
surrounding equipment. Unchecked and unrepaired leaks are a major health
concern for people who inhabit a factory, work or home environment. Certain
gasses and other chemicals can have serious consequences to individual
health from even short term exposure. Water leaks left unchecked create
mold and therefore manifest many allergic responses in employees or customers
exposed. The refrigeration industry is very concerned with the efficient
and quality detection of leaks, as many of the chemicals, such as the
now outlawed CFC (chlorofluorocarbon), can be found in many older refrigeration
units still in use. Those using leak detectors sometimes use 3M respirators.
Alarm only leak detectors give
off an alarm when they detect gas, but do not give any information
about the type or
amount.
Colorimetric leak detectors react chemically with minute leaks and
cause a visible color change in the developer.
Electronic leak detectors can be programmed to detect certain or
multiple refrigerants. After the general area of the leak is detected,
a soap
solution is applied to the area to reveal the precise leak point.
Gas analyzers detect the composition of a specific gas. When a gas
leak is suspected, the analyzer can confirm the existence of a gas
compound in an environment, but cannot pinpoint the exact location
of the leak.
Gas detectors use tracer gasses like hydrogen and helium to find
a leak. After filling the chamber with helium or a hydrogen/nitrogen
mix, the gas loss is measured with a mass spectrometer that detects
the helium or hydrogen.
Leak detection measures the discharge of gases and liquids to find leaks.
Refrigerant leak detectors can detect only chlorinated refrigerants.
A halide torch uses a flame, and if halogenated refrigerant vapors
are present, the flame changes from blue to a blue-green color.
Ultrasonic detectors are
used to detect a wide range of gas leaks. Because gas leaks are noisy,
this technology converts the high frequency leak sound
to a lower range where the hissing of the leak can be heard through
a
set of headphones and traced to the source.
Water leak detectors range
from sensors that monitor moisture levels to sensors that monitor flow
rates and have warning alarms
and auto shut-off devices.
Leak Detectors Terms
Adsorption – The
condensation of gas or vapor on a surface.
Aerosol – The suspension of minute particles in the air.
Analyzer – An
instrument that can determine qualitatively and quantitatively the components
in a mixture.
Blocking – The conditions that cause leak detectors
to malfunction, most commonly a lack of oxygen.
Calibration
– The procedure used to adjust an instrument for proper response.
Combustion – The rapid oxidation of a material that is evolving
heat and light.
Explosive/Flammable Range – The
range of flammable vapor or gas-air mixture between the upper and lower
flammable limits.
Gas – A type
of matter which expands indefinitely to fill a contained space. Gas is
characterized by its low density.
Interference – A gas other than
the one being detected that will cause a false reading on a leak detector.
Leak
Tight – Leakage that is at an acceptable rate for a system
or component.
Non-destructive Testing
(NDT) – The examination
of an object or material with technology that does not affect the object's
future.
Permeation Leak – A leak through a barrier that does not have a
hole or a discrete passage.
Quantitative – The total amount of leakage for any particular system
or component.
Sensor – A device that converts the presence
of a gas or vapor into an electrically measurable signal. The sensor
is
the
heart of a
gas monitor and can also be used to detect other substances, such as
moisture levels.
Toxic Gas or Vapor – Any
substance that causes sickness or death when inhaled or absorbed by the
body.
Tracer Gas – A
gas that, when passing through a leak, is used by a specific leak detector
to help detect the presence of other gasses.
Vapor – The gaseous
state of a material below its boiling point.
Zero Gas – Clean air, and a way of ensuring that a small release
of gas is not near the sensor when honing the sensing signal during calibration.
