ULTIMA® OPIR-5 Open Path Gas Detector EVERY LIFE HAS A PURPOSE…
Contents • Product Overview • False Alarm Immunity • Detector Placement • Installation • Split Concentration Range • Maintenance • Fault Conditions • HART • AMS Device Manager • Applications • Summary
ULTIMA OPIR-5 Detector • Description • Open path infrared hydrocarbon gas monitoring system • Expected Customer Benefits • Low power consumption • Dual analog outputs, ppm•M and LEL•M • Light and compact design • Resilient to solar radiation and fog • Long detection range • Available with HART and Modbus • Stainless steel construction • Integral display
Solar Radiation Rejection • The ULTIMA OPIR-5 has superior immunity to solar radiation and other external IR radiation sources.
Performance Certifications • The ULTIMA OPIR-5 is the world’s first and only open path detector to meet agency performance requirements on both LEL•m and ppm•m scales
Detector Placement • Open path detectors should be installed based on several considerations: • Hazard conditions within the installation area covered • Ventilation rates, direction, and presence of recirculation and dead zones • Sensitivity to low (geometric) sunlight, fog, and reflections • Powerful sources of electromagnetic emissions like high powered electrical towers • Structures that may interfere with line of sight * Health and Safety Executive, Offshore Division,” Fire and Explosion Strategy, Issue 1,” 2004.
Installation • When installing an ULTIMA OPIR-5 detector, it is useful to consider the following: • Vibration can create issues • Solid foundation improves alignment integrity • The longer the line of sight path, the more solid the foundation required • Maintain a 6” to 12” radius around the line of site beam to avoid reflective interference from piping and supports • For outdoor installations, consider maximum snow levels • Good immunity to fog, steam, and rain but immunity degrades over longer distances • Avoid pedestrian traffic or overhead cranes • Keep beam low and down wind for heavy gases like propane and high for light gases like methane

5 LEL•m 5,000 ppm-m (0.1 LEL•m) Methane Gas Concentration (LEL•m) Methane Gas Concentration (ppm-m) 0 4 12 20 AO (mA) Split Concentration Range • With the split range function, users can monitor the entire span of gas concentration with a single analog signal • Reduces wiring and commissioning costs
Alignment • Simple alignment process • Arm or base mounts available • Display • Menus activated by magnet • Enables easy alignment, setup & diagnostics
Maintenance • As with other combustible sensors, the ULTIMA OPIR-5 should be included in the plant maintenance schedule* • Gas check frequency depends on operating conditions (ex. dusty, corrosive, or damp environment) • Before repair or maintenance, the gas detector should be removed to a safe place outside the area being protected • If the hazard is still potentially present, it will be necessary to use a replacement gas detector in the area until the original detector is reinstated * BS EN 50073:1999 “Guide for the selection, installation, use and maintenance of apparatus for the detection and measurement of combustible gases or oxygen.”
Diagnostics • The ULTIMA OPIR-5 has self-diagnostics that inform users when certain types of device failures have occurred
HART • The ULTIMA OPIR-5 is available with HART for better efficiency with remote communication • Only the primary scale, LEL•m or split range, connects through HART • Benefits of the HART-equipped ULTIMA OPIR-5: • Better diagnostics • Improved management of maintenance history and event logging • Flexible and accurate digital transmission • Effective cost control of devices in the field • Installation savings due to fewer wires
HART –Analog Signal for Faults Because HART requires a minimum current for operation, the ULTIMA OPIR-5’s fault conditions use 3.5 mA as minimum analog output On HART-equipped unit, user must select the HART-modified AO in order use AO values below 3.5 mA
AMS Device Manager • Asset management and process improvement • Check compliance to calibration schedule • Coordinate calibrations so as to reduce labor cost • Aggregate calibration to a control room • Track gas level remotely • Read fault conditions from control room; before sending technician to the field
Ultima OPIR-5 Summary • Ultima OPIR-5 Open Path IR Detector • Detects ppm•Meter & LEL•Meter • Path Length up to 150 M • Wide Temperature range • Global Approvals • Integral Display - Easy alignment, diagnostics and maintenance
