Concept and safety
IRmax concept
IRmax
is an ultra-compact infrared (IR) gas detector, which delivers rapid, fail-safe detection
of hydrocarbon gases and vapours.
Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package,
IRmax
is designed to operate in the harshest conditions. Unlike conventional IR gas detectors,
IRmax
does not incorporate heaters to prevent condensation on windows and mirrors. The
S
tay
cl
IR coating on optical components prevents condensation forming while the detector is
operating.
IRmax
is compatible with any 4-20mA control system, and can also be installed in an RS485
Modbus addressable network (see Section 7).
IRmax
requires only 1 Watt of power, typically 75-90% lower than conventional IR gas detectors.
IRmax
features a compact diffusion gas chamber, which in combination with an effective
weatherproof cap provides excellent speed of response. The weatherproof cap has been
designed using flow modelling software to enable remote gassing and calibration of the
IRmax
without requiring a special calibration cap.
The
IR Display
makes it possible to monitor readings from the
IRmax
both locally and
remotely. An
IR Display
can be fitted directly to
IRmax
. Alternatively,
IRmax
may be
supplied with an Intrinsically Safe (IS) Barrier module attached. An
IR Display
can then
be connected to the IS Barrier Module via temporary or permanent cabling. The available
options are illustrated on Diagram 3, page 5.

IRmax
