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. OPERATING PRINCIPLE Three types of mounting thread are available to allow easy fixing to the junction box of the fixed system. On the front face SGX Sensortech manufactures a range of Infrared (IR) Gas there is an external M46 thread for attaching optional Sensors for a variety of gases and vapours in different accessories for use in different applications. The IR600 Series applications. These are compact and robust gas diffusion type incorporates an inbuilt and sealed preamplifier/buffer and sensors based on an SGX Sensortech patented optical require connection to suitable transmitter systems for their design. They run on low power and use well proven Non- power supply, operation and signal processing. The IR600 Dispersive Infrared (NDIR) detection methods. lead in/out terminates in an 8-pin connector. The sensor operates using the natural ability of the target gases to absorb radiation in the infrared portion of the FEATURES electromagnetic spectrum. Using an infrared source, detector and selective optical filters the SGX infrared sensors can be For detection of the following gases: used to detect a range of target gases.

HANDLING PRECAUTIONS 1. Do not allow sensors to fall on the floor. This could cause lamp filament breakage, damage to the pins and the gas entrance aperture. 2. Do not apply mechanical force against the gas entrance aperture. 3. Do not immerse sensors in water or other fluids. 4. Protect the gas entrance aperture against dust ingress and sprayed materials. 5. Anti-static handling precautions must be taken.
