MSA Ultima® OPIR-5 Infrared Open Path Gas Detector

The OPIR-5 Detector 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 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. The OPIR-5 Detector provides two 4 to 20 mA analog signals proportional to each of the above ranges, in addition to a digital display and relay contacts.

The OPIR-5 Detector 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 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 multi point computer-based monitoring.

Features and Benefits

• Dual detection range enables sensitivity to both small (ppm•meter) and large (LEL•meter) gas leaks
• Performance approved for use in harsh environments
• Single detection beam improves accuracy and reduces drift.
• Up to 150 meter path length
• Multiple communication outputs (HART, ModBus, AMS Support) provide complete status and control capability in the control room.
• Unitized display for ease of operation and reduced cost.
• Automatic gain control compensates for dirty optics, rain and fog.
