IR1 Single Gas Series Datasheet
Infrared Single Gas Sensor for Hazardous Environments
(Portable and Fixed Systems)
The SGX infrared sensors use the proven Non-Dispersive
Infrared (NDIR) principle to detect and monitor the presence
of gases. With an infrared source and specific filtering on the
pyroelectric detectors mounted inside the optical/gas cavity,
individual gases or types of gas can be identified and their
concentrations determined.
These sensors are suitable for reliable monitoring of gas
levels in general safety applications where the sensor size is
restricted and require a flameproof enclosure for hazardous
environments.
APPLICATIONS
Oil & Gas
Petrochemical
Biogas
Wastewater
Utilities
Steelworks
Confined Space Entry
Indoor Air Quality
OPERATION
To operate, the sensors must be interfaced to a suitable
circuit for power supply, output amplification and signal
processing. Sensor outputs require linearisation and
compensation for ambient temperature variation using
algorithms in the system firmware. This is necessary for
sensors to meet their full performance specification. An
embedded temperature sensor facilitates this compensation
on certain types. Further compensation for pressure changes
can also be made in an algorithm, provided there is a
suitable input from a pressure sensor.
A set of Application Notes is available from the SGX
Sensortech Ltd website, to explain more about NDIR gas
sensing and provide advice for the end-user on interfacing
the sensors and processing signals.
