Hydrogen Leak Detection for sniffing
applications is being considered by most all companies involved with
the manufacture of units and parts of air conditioners,
refrigerators and automotive components. Hydrogen is the smallest
molecule (even smaller than helium) and has other properties such as
speed through the leak that benefits hydrogen use in sniffer leak
detection applications.
Why Hydrogen and the Sensistor?
First reason for the Sensistor would be Cost. The
cost of a 5% hydrogen/95% nitrogen mixture (non-combustible) is
one-third the cost of helium. When you consider that most tracer
gas is released, that is just dollars going up the stack in
helium. In most facilities, operational cost savings is an ongoing
effort. Many HVAC facilities spend over $100,000 on helium tracer
gas.

Helium Contamination of the leak
checking environment is always an obstacle to finding the leak.
Helium background slows down the leak checking process costing
production time and can send leaking units into the field.
Hydrogen atoms move with a much higher velocity and disperse much
quicker. Using a 5% hydrogen tracer gas, there is less background
than using 100% helium.
Leak Pinpointing is also enhanced
with the speed of hydrogen. The speed of the hydrogen atom through
the leak and quick dispersion once outside the leak, provide a
clean detection area to pinpoint the exact location of the leak.
No more clouds of gas hiding the actual leak.
No High Vacuum Pumps or Moving Parts found in
mass spectrometer leak detectors to worry about in the Sensistor.
The Sensistor uses a microelectronic sensor to detect hydrogen.
No more concern about Clogging
the sniffer probe. Why? The Sensistor measures the leak at the tip
and does not ingest the tracer gas and other contaminants such as
soap, dirt and other substances in the leak test area.
The Sensistor Hydrogen Leak Detector uses forming gas(5% hydrogen 95% nitrogen), Forming
gas in most parts of the country is one-third the cost of helium.
Given that most HVAC and Refrigeration applications require 100%
helium to be effective to find small leaks, the cost savings are
significant. Add to the cost savings the simplicity of the Sensistor,
and the high costs of finding small leaks is significantly reduced.
The Sensistor Hydrogen Leak Detector can find a leak as small as 5 x 10-7 atm
cc leak (with 5% hydrogen/95% nitrogen mixture). Keep in mind that
5% hydrogen is a non-combustible gas and is labeled green. There is
no explosion concerns with 5% mixtures of hydrogen and 95% nitrogen.
