Release S4000C Series
Combustible Gas Detectors with SIL 3 Suitable Rating
Highly
Intelligent Combustible Gas Detectors are
SIL 3 Suitable for Hazardous Environment Processes
in Demanding Industries
Ideal for Oil / Gas Production, Storage, Pipeline,
or Distribution and PetroChemical Refining Applications
With
their highly intelligent microprocessor-based designs,
the advanced
S4000C and S4100C Combustible
Gas Detectors from General Monitors are now suitable
for use in Safety Integrity Level (SIL) 3 applications
commonly found in a wide range of demanding industries
where the potential presence of dangerous hydrocarbon-based
combustible gas is a threat to people, equipment
and facilities.
The global importance of the SIL standard
has grown substantially in the oil/gas, petrochemical
and other process industries over the last 10 years
in response to the development of safety equipment
designed with next-generation electronics. SIL is
a measure of process safety system performance, in
terms of probability of failure on demand (PFD).
This convention was chosen because it is easier to
express the probability of failure rather than that
of proper performance.
There are four discrete integrity
levels associated with SIL: SIL 1, SIL 2, SIL 3,
and SIL 4. The higher the SIL level, the higher the
associated safety level, and the lower probability
that a system will fail to perform properly. As the
SIL level increases, typically the installation and
maintenance costs and complexity of the system also
increase.
S4000C Combustible Gas Detector
The S4000C Detector is a hydrocarbon gas detector
that is suitable for SIL Level 3 applications and
is FM, CSA, ATEX, CE Marking and GOST approved.
It features a three-digit display and an explosion-proof
housing, which allows all data to be processed
locally at the sensor site. The S4000C is also
available with an optional relay configuration
that is appropriate for SIL Level 2 processes.
With
its highly reliable catalytic bead sensor, the S4000C
Detector monitors combustible gas and vapors within
the lower explosive limit (LEL) and provides status
indication and alarm outputs. When the sensor detects
gas, it initiates a 4-20mA alarm signal that is proportionate
to the 0 to 100% LEL gas concentration present and
communicates the alarm notification to the safety system.
S4100C
Combustible Gas Detector
Designed for the European community, the S4100C Detector
is a hydrocarbon gas detector that is suitable
for SIL Level 3 applications and is ATEX, CE Marking,
GOST and Kazakhstan approved. It features a three
digit display and an explosion-proof housing, which
allows all data to be processed locally at the
sensor site.
The S4100C also features a highly reliable
catalytic bead sensor. It is designed to measure and
display concentrations of combustible gases in the
0-100% LEL range, but will continue to display concentrations
up to 120% LEL. The sensing element may be incorporated
in the transmitter housing or remotely mounted at
distances of 600 meters.
GM SIL Resource Center
As part of its commitment to plant safety, SIL and
the industries that it serves, General Monitors
has developed a highly informative Safety Integrity
Level (SIL) Online Resource Center that is located
at: http://www.gmigasandflame.com/sil_lead.html.
The in-depth online SIL Resource Center continues
General Monitors’ 45-year history of focusing
on customer problems by offering a diverse set
of industry leading safety solutions.
