MSA has unveiled the Ultima OPIR-5 Detector, an open-path IR gas detector that provides continuous monitoring of combustible gas concentrations at a path length of up to 150 meters (nearly 500 feet).
The Ultima OPIR-5 features a dual detection range (ppm*meter and LEL*meter), enabling sensitivity to both small and large gas leaks, and is performance approved for use in harsh environments, according to MSA.
The system consists of an IR source and receiver that continuously monitor 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. A single detection beam improves accuracy and reduces drift, the company says.
Applications and Features
Applications include compressor stations, drilling and product platforms, LNG/LPG processing & storage facilities, petrochemical tanks and tank farms, wastewater treatment, train stations and tunnels, nuclear facilities, and oil and gas refineries and production platforms.
The OPIR-5 Detector is easily aligned using the digital display and adjustable mounting arms; it does not require any bulky setup equipment such as digital volt meters and handheld alignment aids, according to MSA. The OPIR-5 Detector’s sensitivity can be checked by placing a test gas film in front of the receiver.
The OPIR-5 Detector 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 OPIR-5 Detector can be transmitted up to 9,000 feet to any industrial analog to digital (A/D) converter for use in multipoint computer-based monitoring.
