OMT364 Oxygen Transmitter for
Hazardous Areas
The Vaisala SPECTRACAP
®
Oxygen
Transmitter OMT364 is designed
for oxygen monitoring in moist and
aggressive process gases.
Laser based measurement
The OMT364 incorporates a
compact tunable diode laser (TDL)
gas spectrometer built in the
measurement probe. This optical
measurement technology is well
known for unmatched stability
and robustness. The patented
SPECTRACAP
®
sensor offers uniquely
TDL technology in a compact probe
suitable for eld use.
FM Approved OMT364 for
Hazardous Areas
The non-incendive OMT364
transmitter is permitted for use in
Class I, Division 2 of the NEC

®
Oxygen Transmitter OMT364 for hazardous areas.
instrument can be installed in areas
that are classi ed as Class I, Division
1 or 2.
Direct installation
In many applications, the OMT364
can be ange-mounted directly into
a process. No sampling or sample
conditioning equipment is needed.
This feature provides real time
measurement data without sampling
or sample switching delays.
Sampling cell installation
An optional sampling cell is
available for processes with high
temperatures, elevated pressures
or extremely dif cult mechanical
conditions. Due to the robustness of
the SPECTRACAP
®
sensor and its low
sensitivity to gas ow and pressure
variations, the sampling system is
simple and it can be installed near
the sampling point.
