What is gas warning system?
The gas warning system is a
lifesaving system that monitors the atmosphere within any enclosed space. As
the gas that is being monitored gets increased above a preset threshold level,
an acoustic alarm is triggered, so that the caretaker of this monitor can look
into the matter.
The chambers
used to test the devices of gas warning are built and operated differently. The
basic work of gas warning devices is to alarm you is to give you an alarm if there is any gas leakage in the
system. They can be used for domestic usages too. In that case, usage of gas is
also reduced. The works that the device will be doing for you are all
specifying the risks that are affiliated with. So, the testing part is even
more critical. A vacuum high-pressure
test chamber is usually designed for the purpose.
The style of
operation
Before moving to
any other thing, it is important to understand the parameters that the testing
device will be checking. In the case of
the devices providing a gas warning,
there are three issues to be checked.
·
Temperature
·
Pressure, and
·
Humidity
The parameters
are changed in all the tests. It is to be noted that only one parameter is to
be changed in a single test, where other two will remain constant. This is to
ensure that the device is reading the values for all the alterations
separately. The test is to be carried out in a synthetic atmosphere. After it
is tested in the synthetic air, the same test has to be pursued in an
atmosphere of fuel gas. The quantity or
the density of the gas in the cold heat climate vacuum must be as per
the norms. Both the tests will be showing the signal that the gas device will
show at the end.
The signals
received, according to the change of parameters are recorded and expressed in
the form of a graph. The output is
usually stored in the form of data in carriers. The components that are used in
the test are made of stainless steel. It has to be noticed that silicon never
comes in contact with any of the test elements. It will totally destroy the
specimen.
Controlling
the test
The test is
controlled through a PC. The software is
installed to run the setup. It has to be mounted on a controller named as
STRANGE. The door of the cold heat climate vacuum test chamber will be
opening and closing in a pneumatic frequency. While the door will be opened,
the external illuminations will turn on. For the support of the test, the
chamber is fixed to the bottom. However, to move the chamber at the middle,
there are castor wheels attached.
