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. FEATURES • • • • • • • • • • • • • • • • • For detection of the following gases: o Carbon Dioxide (IR601), o Hydrocarbons (IR602, IR603) o Acetylene (IR604) Diffused gas sampling via sinter Low power Reference channel for self-compensation Special gold plated optical/gas cavity for stable signal levels Operational in varying temperature, pressure and humidity Fast response Rugged stainless steel construction No moving parts Resistance to corrosion Immunity from ‘poisoning’ Reliable fail-safe operation Low maintenance Sealed preamplifier/buffer electronics Accessories available for field applications ATEX certified CSA certified (Canada and US) OPERATING PRINCIPLE SGX Sensortech manufactures a range of Infrared (IR) Gas Sensors for a variety of gases and vapours in different applications. These are compact and robust gas diffusion type sensors based on an SGX Sensortech patented optical design. They run on low power and use well proven NonDispersive Infrared (NDIR) detection methods. The sensor operates using the natural ability of the target gases to absorb radiation in the infrared portion of the electromagnetic spectrum. Using an infrared source, detector and selective optical filters the SGX infrared sensors can be used to detect a range of target gases. More information on the NDIR sensors can be found in the SGX Sensortech Application Notes.
