IMPORTANT
Be sure to read and understand the entire
instruction manual before installing or operating
the gas detection system. This product is intended
to provide early warning of the presence of a
flammable or explosive gas mixture. Proper
device installation, operation, and maintenance is
required to ensure safe and effective operation.
APPLICATION
The Open Path Eclipse
™
Model OPECL is an open path
infrared gas detection system that provides continuous
monitoring of combustible hydrocarbon gas
concentrations in the range of 0 to 5 LFL-meters.
Standard system outputs include an electrically
isolated/non-isolated 4-20 mA dc current output, with
HART communication and RS-485 MODBUS
communication. Alarm and fault relays are available as
an option.
The system consists of two stainless steel modules — a
transmitter and a receiver, along with mounting fixture
hardware. Both modules are powered from an external
24 volt DC supply. The receiver provides the
measurement signal outputs, and is furnished with an
onboard "status indication" LED and an internal
magnetic calibration switch. The transmitter houses
redundant xenon flashlamps. Both modules are
installed at approximately the same elevation and must
be aligned to point directly at one another. No direct
electrical interconnection between the two modules is
required.
The Open Path Eclipse is ideal for use in harsh outdoor
environments and is certified explosion-proof for use in
Class I, Division 1 and Division 2 hazardous areas. It
can be used as a stand-alone detector, or as part of a
larger facility protection system using other Det-Tronics
equipment such as the Eagle Quantum Premier Fire and
Gas Detection/Releasing System or the R8471 Series
Controller.
