MODEL IR5500 Open Path Gas Detector Features • Dual detection ranges • Sensitive to both small (ppm•meter) and large (LEL•meter) gas leaks • Performance approved • Ideal for use in harsh environments • Single detection beam • Improves accuracy and reduces drift • Continuous self-check • Fail to safe operation • Multiple communication outputs (HART, Modbus, AMS Support) • Provides complete status and control capability in the control room • Unitized display • Ease of operation, reduced cost • Automatic gain control • Compensates for dirty optics, rain, and fog The Model IR5500 is an open path IR gas detector that provides continuous monitoring of methane and propane gas concentrations. The system consists of an IR source and receiver which continuously monitors for methane in both the 0 to 5000 ppm• meter and 0 to 5 LEL• meter range. A 0 to 2000 ppm• meter and 0 to 1 LEL• meter range is also available for monitoring propane. The IR5500 provides two 4 to 20 mA analog signals proportional to each of the above ranges, in addition to a digital display and relay contacts. • Compressor Stations The IR5500 is easily aligned using the digital display and adjustable mounting arms, therefore it does not require any bulky setup equipment (e.g. digital volt meters, handheld alignment aids). The IR5500ʼs 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. It also requires little maintenance save for a periodic visual inspection, test gas film check, and cleaning of the windows to assure dependable performance. Sensor data and status information from the IR5500 can be transmitted up to 9,000 feet to any industrial analog to digital (A/D) converter for use in multipoint computer-based monitoring. • Drilling and Production Platforms • Fence Line Monitoring • Fuel Loading Facilities • Gas Turbines • LNG/LPG Processing and Storage Facilities • Petrochemical Tanks • Tank Farms • Wastewater Treatment
