IR Sensors for hazardous areas

The IR600 Series gas sensors are designed to detect and monitor the presence of CO2, hydrocarbons and acetylene using the same non-dispersive infrared (NDIR) principle as used in the SGX Sensortech range of miniature infrared gas sensors. Dual detector channels are used with a reference for background compensation. A temperature sensor is mounted for temperature compensation.

IR600 sensors are designed to be integrated with fixed gas detection systems. Their construction is a stainless steel flameproof enclosure with an integral stainless steel sinter for the safe entry of the gases being tested.

Three types of mounting thread are available to allow easy fixing to the junction box of the fixed system. On the front face there is an external M46 thread for attaching optional accessories for use in different applications. The IR600 Series incorporates an inbuilt and sealed preamplifier/buffer and require connection to suitable transmitter systems for their power supply, operation and signal processing. The IR600 lead in/out terminates in an 8-pin connector.

For detection of the following gases:

• Carbon Dioxide (IR601)
• Hydrocarbons (IR602, IR603)
• Acetylene (IR604)

Gas concentration ranges:

• 0 – 5% Carbon Dioxide
• 0 – 100% LEL and 0 – 100% vol. Hydrocarbons (same sensor is suitable for both ranges)
• 0 – 100% LEL and 0 – 100% vol. Acetylene (same sensor is suitable for both ranges)
