With an advanced feature set, the new IR5500 Open Path Gas Detector from General Monitors redefines the industry standard as the ‘first and only open path detector to meet agency performance requirements’ on both the LEL meter and ppm meter scales.
The device is the industry’s first detector with split range scale for ppm meter and LEL meter monitoring, according to the company, and is the first to be certified for operation at -55ºC.
It is also among the first major open path detectors certified to FM approvals, EN, and IECEx performance standards.
Outdoor combustible gas leaks pose a significant danger at petrochemical facilities, as well as in electric utility, wastewater treatment, and other hazardous operation plants. Leak sources typically include pipelines, valves, tanks, burners, compressors, separators, flare systems, aeration ponds, and other equipment.
The IR5500 Open Path Gas Detector provides continuous monitoring of combustible gas concentrations. The system consists of an IR source and receiver, which continuously monitors for methane in both the 0 to 5,000 ppm meter and 0 to 5 LEL meter range.
The IR5500’s advanced infrared sensor technology features a single beam detection design, which improves accuracy and reduces drift. The design of the sensor includes continuous self-check monitoring for fail to safe operation. Automatic gain control compensates for dirty optics, rain, and fog – the result is precision accuracy with exceptional reliability in harsh environments and improved false alarm rejection.
Unlike most open path detectors, the IR5500 features a built-in display, which simplifies installation and maintenance while reducing the total cost of ownership. The IR5500 requires no tools for alignment at any range and can be aligned without a scope at 100 meters or more.
The IR5500’s sensitivity can be checked by placing a test gas film in front of the receiver. The IR5500 is calibrated at the factory and needs no further calibration, while it also requires little maintenance other than a periodic visual inspection, test gas film check, and cleaning of the windows to ensure dependable performance.
