Model IR5500 provides continuous monitoring of combustible gas concentrations. The system consists of an infrared source and receiver that continuously monitor for methane in both the 0 to 5,000 ppm-meter and 0 to 5 LEL-meter ranges. Two other scales (0 to 2,000 ppm-meter and 0 to 1 LEL-meter) are available for monitoring propane. The open path gas detector provides two 4 to 20 mA analog signals proportional to the standard ranges in addition to a digital display and relay contacts. It utilizes a single-beam-detection design to improve accuracy and reduce drift.
