A New Application Standard in Infrared Gas Sensing

If you are using a flammable gas detector, then it is almost certainly fitted with either a catalytic bead (pellistor) or infra-red sensor. The sensor converts the combustible gas concentration into an electrical signal that the instrument can process and react accordingly. Both technologies have advantages; pellistors are relatively inexpensive and are sensitive to a wide range of flammable gases, infra-red sensors are extremely robust to environmental contamination and mechanically strong. However in some difficult applications where there are repeatable poisons and wet conditions, catalytic sensors are not compatible and infrared sensors can develop condensation inside the optical cavity when powered down, then when re-powered the condensation can put the infrared sensor into a latched false alarm state. The choice of technology utilised has often depended on a compromise between cost and reliability and infrared sensors should be designed to offer excellent reliability even within wet condensation applications like mining or tunnelling.

The INIR infrared sensor range from SGX Sensortech provides instrument manufacturers and instrument users with not only a full linearized, temperature compensated output but also with additional condensation compensation. The hardware and firmware within the sensor detect the occurrence of condensation and reduce power up false alarms within wet applications and at the same time allowing trouble free gas detection within the wet application. Why would you compromise and accept a lower performing infrared gas sensor, choose SGX INIR infrared gas sensors.

The SGX Sensortech - INIR infrared gas sensors offer key benefits:

• Superior resistance to humidity and condensation - the sensor is fitted with novel hardware and firmware to detect and compensate for optical occlusion from condensation.
• Mechanical robustness - the INIR range uses a unique shock mounted infrared source which means that it is very resistant to mechanical shocks and vibration.
• Simple usage - the SGX Sensortech INIR infrared sensors are supplied with calibrated auto ranging digital and analogue temperature compensated outputs.
• Bus connectivity - Each sensor has a unique addressable code, when connected up to a multisensory bus enabling the user to communicate and interrogate individual sensors to allow individual gas zone monitoring.
• Gas versions - Methane, Carbon dioxide, Propane and Butane
• Low operating power - the INIR series when operated constantly offers an average power consumption < 120mW
