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.
