The NGA 2000 HFID Heated Hydrocarbon Analyzer Module uses flame ionization detection (FID) technology to continuously measure total hydrocarbon concentration in sample gas at any user selectable temperature between 200°F and 400°F. The heated module eliminates typical measurement errors associated with the loss of hydrocarbon compounds due to condensation. The HFID is an extremely versatile instrument due to its ability to accept hot gas sample. Applications such as internal combustion engine emissions (ICEE), ambient air safety monitoring, carbon bed absorber monitoring, etc. can all benefit from increased accuracy and simplified sample handling requirements associated with the HFID analyzer module. The NGA 2000 HFID analyzer module is a self-contained unit, complete with heated detector assembly and associated electronics. The modular design allows for easy system integration, expandability, and enough flexibility to reach well into the next century. The HFID module may be a "stand alone" instrument with the addition of our Input/Output (I/O) module and platform or it can be integrated into a sophisticated multicomponent analyzer network. What makes the NGA 2000 Series Analyzer Modules unique is their built-in intelligence and their ability to share that intelligence. Embedded in the NGA 2000 architecture is an advanced digital communication network (LON) which allows interaction between other analyzer outputs and diagnostic variables to a centralized display panel on the plarform or to a remote PC. Because of this distinctive feature, the HFID Analyzer Module may either be incorporated into a panel/rack or it can be placed near the sample source up to a mile away, thereby further reducing sample handling requirements. FEATURES In our continuing effort to improve technology, Emerson has integrated our superior flame ionization detection design into a heated analyzer module. In addition, the NGA 2000 HFID Analyzer Module contains a software-independent safety design which creates a fully reliable shutdown system for plant and personnel safety. As required by Nationally Recognized Testing Laboratories (NRTL), the HFID is designed to meet NFPA 496 regulations via continuous dilution purge. This entails purging the analyzer with four times its volume prior to flame ignition and includes automatic fuel shutoff due to loss of flame or purge air. The HFID Analyzer Module is therefore truly designed to meet all of your safety requirements. The NGA 2000 HFID Analyzer Module houses all components in contact with sample gas in an internal oven compartment. Oven temperature is maintained at any user selectable set point between 200°F and 400°F. Therefore, the HFID provides increased measurement accuracy over conventional FID analyzers because the elevated operating temperature prevents hydrocarbon compounds from condensing before they reach the detector. The HFID Analyzer Module contains performance features as well as diagnostics that put it ahead of the competition via response time, accuracy, ease of service and maintenance. The microprocessor based operation of the NGA 2000 Series provides on-line diagnostics and network communication capabilities which reduce cost through centralized data processing and analyzer maintenance. Diagnostics can be monitored while the analyzer is in service allowing service requirements to be anticipated and downtime minimized. The analyzer is equipped with four user-selectable ranges and auto ranging capability. The analyzer can also be equipped with auto calibration cycle. The digital communication network (LON) allows communication of numerous physical parameters and diagnostic information like oven temperature, flame status, burner air and fuel pressure, safety purge status, etc. between the analyzer and a remote platform or PC. In addition to network operation, digital I/O's are available to monitor and control analyzer functions.
